14 CONTAMATION MANAGEMENT HYDRAULIC FLUIDS The fl uid is the vector that transmits power, energy within an oleodynamic circuit. In addition to transmitting energy through the circuit, it also performs additional functions such as lubrication, protection and cooling of the surfaces. The classifi cation of fl uids used in hydraulic systems is coded in many regulatory references, different Standards. The most popular classifi cation criterion divides them into the following families: - MERAL OILS Commonly used oil deriving fl uids. - FIRE RESISTANT FLUIDS Fluids with intrinsic characteristics of incombustibility or high fl ash point. - SYNTHETIC FLUIDS Modifi ed chemical products to obtain specifi c optimized features. - ECOLOGICAL FLUIDS Synthetic or vegetable origin fl uids with high biodegradability characteristics. The choice of fl uid for an hydraulic system must take into account several parameters. These parameters can adversely affect the performance of an hydraulic system, causing delay in the controls, pump cavitation, excessive absorption, excessive temperature rise, effi ciency reduction, increased drainage, wear, jam/block or air intake in the plant. The main properties that characterize hydraulic fl uids and affect their choice are: - DYNAMIC VISCOSITY It identifi es the fl uid s resistance to sliding due to the impact of the particles forming it. - CEMATIC VISCOSITY It is a widespread formal dimension in the hydraulic fi eld. It is calculated with the ratio between the dynamic viscosity and the fluid density. Cinematic viscosity varies with temperature and pressure variations. - VISCOSITY DEX This value expresses the ability of a fluid to maintain viscosity when the temperature changes. A high viscosity index indicates the fluid s ability to limit viscosity variations by varying the temperature. - FILTERABILITY DEX It is the value that indicates the ability of a fluid to cross the filter materials. A low fi lterability index could cause premature clogging of the fi lter material. - WORKG TEMPERATURE Working temperature affects the fundamental characteristics of the fluid. As already seen, some fl uid characteristics, such as cinematic viscosity, vary with the temperature variation. When choosing a hydraulic oil, must therefore be taken into account of the environmental conditions in which the machine will operate. - COMPRESSIBILITY MODULE Every fl uid subjected to a pressure contracts, increasing its density. The compressibility module identifies the increase in pressure required to cause a corresponding increase in density. - HYDROLYTIC STABILITY It is the characteristic that prevents galvanic pairs that can cause wear in the plant/system. - ANTIOXIDANT STABILITY AND WEAR PROTECTION These features translate into the capacity of a hydraulic oil to avoid corrosion of metal elements inside the system. - HEAT TRANSFER CAPACITY It is the characteristic that indicates the capacity of hydraulic oil to exchange heat with the surfaces and then cool them. FLUID CONTAMATION Whatever the nature and properties of fluids, they are inevitably subject to contamination. Fluid contamination can have two origins: - ITIAL CONTAMATION Caused by the introduction of contaminated fl uid into the circuit, or by incorrect storage, transport or transfer operations. - PROGRESSIVE CONTAMATION Caused by factors related to the operation of the system, such as metal surface wear, sealing wear, oxidation or degradation of the fluid, the introduction of contaminants during maintenance, corrosion due to chemical or electrochemical action between fluid and components, cavitation. The contamination of hydraulic systems can be of different nature: - SOLID CONTAMATION For example rust, slag, metal particles, fi bers, rubber particles, paint particles - or additives - LIQUID CONTAMATION For example, the presence of water due to condensation or external infi ltration or acids - GASEOUS CONTAMATION For example, the presence of air due to inadequate oil level in the tank, drainage in suction ducts, incorrect sizing of tubes or tanks. EFFECTS OF CONTAMATION ON HYDRAULIC COMPONENTS Solid contamination is recognized as the main cause of malfunction, failure and early degradation in hydraulic systems. It is impossible to delete it completely, but it can be effectively controlled by appropriate devices. CONTAMATION PRESENCE OF LARGE TOLERANCES CONTAMATION PRESENCE OF NARROW TOLERANCES Solid contamination mainly causes surface damage and component wear. - ABRASION OF SURFACES Cause of leakage through mechanical seals, reduction of system performance, failures. Introduction

15 CONTAMATION MANAGEMENT - SURFACE EROSION Cause of leakage through mechanical seals, reduction of system performance, variation in adjustment of control components, failures. - ADHESION OF MOVG PARTS Cause of failure due to lack of lubrication. - DAMAGES DUE TO FATIGUE Cause of breakdowns and components breakdown.stem performance, failures. - MODIFICATION OF FLUID PROPERTIES (COMPRESSIBILITY MODULE, DENSITY, VISCOSITY) Cause of system s reduction of effi ciency and of control. It is easy to understand how a system without proper contamination management is subject to higher costs than a system that is provided. - MATENANCE Maintenance activities, spare parts, machine stop costs - ENERGY AND EFFICIENCY Efficiency and performance reduction due to friction, drainage, cavitation. ABRASION EROSION MEASURG THE SOLID CONTAMATION LEVEL ADHESION FATIGUE The level of contamination of a system identifi es the amount of contaminant contained in a fl uid. This parameter refers to a unit volume of fl uid. The level of contamination may be different at different points in the system. From the information in the previous paragraphs it is also apparent that the level of contamination is heavily infl uenced by the working conditions of the system, by its working years and by the environmental conditions. What is the size of the contaminating particles that we must handle in our hydraulic circuit? Liquid contamination mainly results in decay of lubrication performance and protection of fl uid surfaces. DISSOLVED WATER - CREASG FLUID ACIDITY Cause of surface corrosion and premature fl uid oxidation - GALVANIC COUPLE AT HIGH TEMPERATURES Cause of corrosion FREE WATER - ADDITIONAL EFFECTS - DECAY OF LUBRICANT PERFORMANCE Cause of rust and sludge formation, metal corrosion and increased solid contamination - BATTERY COLONY CREATION Cause of worsening in the fi lterability feature - ICE CREATION AT LOW TEMPERATURES Cause damage to the surface - ADDITIVE DEPLETION Free water retains polar additives HUMAN HAIR (7 µm) Contamination level analysis is signifi cant only if performed with a uniform and repeatable method, conducted with standard test methods and suitably calibrated equipment. To this end, ISO has issued a set of standards that allow tests to be conducted and express the measured values in the following ways. - GRAVIMETRIC LEVEL - ISO 0 MIMUM DIMENSION VISIBLE HUMAN EYES (0 µm) TYPICAL CONTAMANT DIMENSION A HYDRAULIC CIRCUIT ( µm) The level of contamination is defi ned by checking the weight of particles collected by a laboratory membrane. The membrane must be cleaned, dried and desiccated, with fl uid and conditions defi ned by the Standard. The volume of fl uid is fi ltered through the membrane by using a suitable suction system. The weight of the contaminant is determined by checking the weight of the membrane before and after the fl uid fi ltration. Gaseous contamination mainly results in decay of system performance. - CUSHION SUSPENSION Cause of increased noise and cavitation. - FLUID OXIDATION Cause of corrosion acceleration of metal parts. Introduction

16 CONTAMATION MANAGEMENT - CUMULATIVE DISTRIBUTION OF THE PARTICLES SIZE - ISO 06 The level of contamination is defined by counting the number of particles of certain dimensions per unit of volume of fluid. Measurement is performed by Automatic Particle Counters (APC). Following the count, the contamination classes are determined, corresponding to the number of particles detected in the unit of fluid. The most common classification methods follow ISO 06 and SAE AS 09 (Aerospace Sector) regulations. NAS 68 is still used although obsolete. Classification example according to ISO 06 The code refers to the number of particles of the same size or greater than, 6 or μm in a ml fluid. Class > µm (c) = 0 particles > 6 µm (c) = 00 particles > µm (c) = particles 6 / / Number of particles per ml Over Up to ISO 06:07 Cleanliness Code System Microscope counting examines the particles differently to APCs and the code is given with two scale numbers only. These are at µm and µm equivalent to the 6 µm (c) and µm (c) of APCs.

17 CONTAMATION MANAGEMENT - CUMULATIVE DISTRIBUTION OF THE PARTICLES SIZE - SAE AS 09- and SAE AS 09- Classification example according to SAE AS 09- and SAE AS 09- The code, prepared for the aerospace industry, is based on the size, quantity, and particle spacing in a 00 ml fluid sample. The contamination classes are defined by numeric codes, the size of the contaminant is identified by letters (A-F). It can be made a differential measurement (Table ) or a cumulative measurement (Table ) Class Class µm (c) µm (c) 8 µm (c) 8 70 µm (c) >70 µm (c) µm (c) = 000 particles µm (c) = 00 particles 8 µm (c) = 00 particles 8 70 µm (c) = particles > 70 µm (c) = particles Class 6 > µm (c) A >6 µm (c) B > µm (c) = 000 particles > 6 µm (c) = 000 particles > µm (c) = 00 particles > µm (c) = 0 particles > 8 µm (c) = particles > 70 µm (c) = particle Class from F to E Table - Class for differential measurement Dimension of contaminant Table - Class for cumulative measurement Dimension of contaminant > µm (c) C > µm (c) D >8 µm (c) E >70 µm (c) F CLASSES OF CONTAMATION ACCORDG TO NAS 68 (January 96) The NAS system was originally developed in 96 to define contamination classes for the contamination contained within aircraft components. The application of this standard was extended to industrial hydraulic systems simply because nothing else existed at the time. The coding system defines the maximum numbers permitted of 00ml volume at various size intervals (differential counts) rather than using cumulative counts as in ISO 06:999. Although there is no guidance given in the standard on how to quote the levels, most industrial users quote a single code which is the highest recorded in all sizes and this convention is used on MP Filtri APC s. The contamination classes are defined by a number (from 00 to ) which indicates the maximum number of particles per 00 ml, counted on a differential basis, in a given size bracket. Class Size Range Classes (in microns) Maximum Contamination Limits per 00 ml > µm (c) = 000 particles µm (c) = 00 particles 0 µm (c) = 0 particles 0 00 µm (c) = 8 particles > 00 µm (c) = particles Class NAS CUMULATIVE DISTRIBUTION OF THE PARTICLES SIZE - ISO The level of contamination is defined by counting the number of particles collected by a laboratory membrane per unit of fluid volume. The measurement is done by a microscope. The membrane must be cleaned, dried and desiccated, with fluid and conditions defined by the Standard. The fluid volume is filtered through the membrane, using a suitable suction system. The level of contamination is identified by dividing the membrane into a predefined number of areas and by counting the contaminant particles using a suitable laboratory microscope.

The efficiency of microfibre and paper filtration (ßx(c)) is defined through a lab test called Multipass Test. The efficiency value (ßx(c)) is defined as the ratio between the number of particles of certain dimensions detected upstream and downstream of the filter. Upstream particles number > X µm(c) = ßx(c) Downstream particles number > X µm(c) FILTRATION TECHNOLOGIES Various mechanisms such as mechanical stoppage, magnetism, gravimetric deposit, or centrifugal separation can be used to reduce the level of contamination. The mechanical stoppage method is most effective and can take place in two ways: - SURFACE FILTRATION It is by direct interception. The filter prevents particles larger than the pores from continuing in the plant / system. Surface filters are generally manufactured with metal canvases or meshes. - DEPTH FILTERG Filters are constructed by fiber interlacing. Such wraps form pathways of different shapes and sizes in which the particles remain trapped when they find smaller apertures than their diameter. Depth filters are generally produced with papers impregnated with phenolic resins, metal fibers or inorganic fibers. In inorganic fiber filtration, commonly called microfibre, the filtering layers are often overlapped in order to increase the ability to retain the contaminant.

Poor filtration stability is the cause of the filtering quality worsening as the filter life rises. Low dirt holding capacity causes a reduction in the life of the filter.

19 CONTAMATION MANAGEMENT 6 RECOMMENDED CONTAMATION CLASSES Any are the nature and the properties of fl uids, they are inevitably subject to contamination. The level of contamination can be managed by using special components called fi lters. Hydraulic components builders, knowing the problem of contamination, recommend the fi ltration level appropriate to the use of their products. Example of recommended contamination levels for pressures below 0 bar. Piston pumps with fi xed fl ow rate Piston pumps with variable fl ow rate Vane pumps with fi xed fl ow rate Vane pumps with variable fl ow Engines Hydraulic cylinders Actuators Test benches Check valve Directional valves Flow regulating valves Proportional valves Servo-valves Flat bearings Ball bearings ISO 06 CODE Recommended fi ltration ßx(c).000 The common classifi cation of fi lters is determined by their position in the plant. 7 0/8/ ß 0(c) >000 TYPES OF FILTERS 9/7/ ß (c) >000 8/6/ 7// ß 0(c) ß 7(c) >000 >000 Suction filters They are positioned before the pump and are responsible for protecting the pump from dirty contaminants. It also provides additional fl ow guidance to the pump suction line. Being subject to negligible working pressures are manufactured with simple and lightweight construction. They are mainly produced with gross grade surface fi ltrations, mainly 60 μm. They can be equipped with a magnetic column for retaining ferrous particles. They are generally placed under the fl uid head to take advantage of the piezometric thrust of the fl uid and reduce the risk of cavitation. There are two types of suction fi lters: - IMMERSION FILTERS Simple fi lter element screwed on the suction pipe 6// ß 7(c) >000 - FILTERS WITH CONTAER Container fi lters that are more bulky, but provide easier maintenance of the tank //0 ß (c) >000 Delivery (or Pressure) filters They are positioned between the pump and most sensitive regulating and controlling components, such as servo valves or proportional valves, and are designed to ensure the class of contamination required by the components used in the circuit. Being subjected to high working pressures are manufactured with more robust and articulated construction. In particular situations of corrosive environments or aggressive fl uids can be made of stainless steel. They are mainly produced with fi ltering depths of μm. They can be manufactured with in-line connections, with plate or fl ange connections or directly integrated into the circuit control blocks / manifolds. They can also be manufactured in duplex confi guration to allow the contaminated section to be maintained even when the plant / system is in operation without interruption of the working cycle. Return filters They are positioned on the return line to the tank and perform the task of fi ltering the fl uid from particles entering the system from the outside or generated by the wear of the components. They are generally fi xed to the reservoir (for this reason also called top tank mounted), positioned semi-immersed or completely immersed. The positioning of the return fi lters must guarantee in all operating conditions that the fl uid drainage takes place in immersed condition; this is to avoid creating foams in the tank that can cause malfunctions or cavitation in the pumps. For the sizing of the return fi lters, account must be taken of the presence of accumulators or cylinders that can make the return fl ow considerably greater than the pump suction fl ow rate. Being subject to contained working pressures are manufactured with simple and lightweight construction. Normally it is possible to extract the fi lter element without disconnecting the fi lter from the rest of the system. Combined filters They are designed to be applied to systems with two or more circuits. They are commonly used in hydrostatic transmission machines where they have a dual fi ltration function of the return line and suction line of the hydrostatic transmission pump. The fi lter is equipped with a valve that keeps the 0. bar pressure inside the fi lter. A portion of the fl uid that returns to the tank is fi ltered by the return fi lter element, generally produced with absolute fi ltration, and returns to the transmission booster pump. Only excess fl uid returns to the tank through the valve. The internal pressure of the fi lter and the absolute fi ltration help to avoid the cavitation phenomenon inside the pump. Off-line filters They are generally used in very large systems / plants, placed in a closed circuit independent from the main circuit. They remain in operation regardless of the operation of the main circuit and are crossed by a constant fl ow rate. They can also be manufactured in duplex confi guration to allow the contaminated section to be maintained even when the unit is in operation without interruption of the work cycle. Venting filters During the operation of the plants, the fl uid level present in the reservoir changes continuously. The result of this continuous fl uctuation is an exchange of air with the outside environment. The venting fi lter function, positioned on the tank, is to fi lter the air that enters the tank to compensate for fl uid level variations. 7 Introduction

20 CONTAMATION MANAGEMENT FILTER CHOICE PARAMETERS 8 9 APPLICABLE STANDARDS FOR FILTER DEVELOPMENT The choice of the fi lter system for an hydraulic system is infl uenced by several factors. It is necessary to consider the characteristics of the various components present in the plant and their sensitivity to contamination. It is also necessary to consider all the tasks that the fi lter will have to do within the plant: - FLUID PROTECTION FROM CONTAMATION - PROTECTION OF OLEODYNAMIC COMPONENTS SENSITIVE TO CONTAMATION - PROTECTION OF OLEODYNAMIC PLANTS FROM ENVIRONMENTAL WASTE - PROTECTION OF OLEODYNAMIC PLANTS FROM CONTAMATION CAUSED BY COMPONENTS FAILURES The advantages of proper positioning and sizing of the fi lters are - MORE RELIABILITY OF THE SYSTEM - LONGER LIFE OF THE FLUID COMPONENTS - REDUCTION OF STOP TIME - REDUCTION OF FAILURE CASUALITIES Each hydraulic fi lter is described by general features that identify the possibility of use in different applications. MAXIMUM WORKG PRESSURE (Pmax) The maximum working pressure of the filter must be greater than or equal to the pressure of the circuit section in which it will be installed. PRESSURE DROP ( P) The pressure drop depends on a number of factors, such as the working circuit temperature, the fl uid viscosity, the fi lter element cleaning condition. WORKG TEMPERATURE (T) The working temperature deeply affect the choice of materials. Excessively high or low temperatures may adversely affect the strength of the materials or the characteristics of the seals. FILTRATION EFFICIENCY (%) / FILTRATION RATIO (ß x(c) ) Filtration efficiency is the most important parameter to consider when selecting a fi lter. When choosing the filtration performances, the needs of the most sensitive components in the system must be considered. FLUID TYPE The type of fl uid infl uences the choice of fi lters in terms of compatibility and viscosity. It is always mandatory to check the fi lterability. PLACEMENT THE PLANT The position of the filter in the system conditions the efficiency of all filter performances. In order to obtain unique criteria for development and verification of the fi lters performance, specifi c regulations for the fi lters and fi lter elements testing have been issued by ISO. These norms describe the target, the methodology, the conditions and the presentation methods for the test results. ISO 9 Hydraulic fl uid power -- Filter elements -- Verifi cation of collapse/burst pressure rating This Standard describes the method for testing the collapse / burst resistance of the fi lter elements. The test is performed by crossing the contaminated fl uid fi lter element at a predefi ned fl ow rate. The progressive clogging of the fi lter element, determined by contamination, causes an increase in differential pressure. ISO 9 Hydraulic fl uid power -- Filter elements -- Verifi cation of fabrication integrity and determination of the fi rst bubble point This Standard describes the method to verify the integrity of the assembled fi lter elements. It can be used to verify the quality of the production process or the quality of the materials by verifying the pressure value of the fi rst bubble point. ISO 9 Hydraulic fl uid power -- Filter elements -- Verifi cation of material compatibility with fl uids This Standard describes the method to verify the compatibility of materials with certain hydraulic fl uids. The test is carried out by keeping the element (the material sample) immersed in the fl uid under high or low temperature conditions for a given period of time and verifying the retention of the characteristics. ISO 7 Hydraulic fl uid power -- Filter elements -- Method for end load test This Standard describes the method for verifying the axial load resistance of the fi lter elements. After performing the procedure described in ISO 9, the designed axial load is applied to the fi lter element. To verify the test results, then the test described in ISO 9 is performed. ISO 968 Hydraulic fl uid power -- Filters -- Evaluation of differential pressure versus fl ow characteristics This Standard describes the method for checking the pressure drop across the fi lter. The test is carried out by crossing the fi lter from a given fl uid and by detecting upstream and downstream pressures. Some of the parameters defi ned by the Standard are the fl uid, the test temperature, the size of the tubes, the position of the pressure detection points. ISO 6889 Hydraulic fl uid power -- Filters -- Multi-pass method for evaluating fi ltration performance of a fi lter element This Standard describes the method to check the fi ltration characteristics of the fi lter elements. The test is performed by constant introduction of contaminant (ISO MTD). The characteristics observed during the test are the fi ltration effi ciency and the dirty holding capacity related to the differential pressure. Introduction 8

21 CONTAMATION MANAGEMENT ISO 8 Hydraulic fl uid power -- Filter elements -- Determination of resistance to fl ow fatigue using high viscosity fl uid This Standard describes the method for testing the fatigue resistance of the fi lter elements. The test is carried out by subjecting the fi lter to continuous fl ow variations, thus differential pressure, using a high viscosity fl uid. ISO 70 Hydraulic fl uid power -- Sequence of tests for verifying performance characteristics of fi lter elements The Standard describes the method for testing the performance of fi lter elements. The protocol described by the regulations provides the sequence of all the tests described above in order to verify all the working characteristics (mechanical, hydraulic and fi ltration). Saturation Levels Since the effects of free (also emulsifi ed) water is more harmful than those of dissolved water, water levels should remain well below the saturation point. However, even water in solution can cause damage and therefore every reasonable effort should be made to keep saturation levels as low as possible. There is no such thing as too little water. As a guideline, we recommend maintaining saturation levels below 0% in all equipment. TYPICAL WATER SATURATION LEVEL FOR NEW OILS Examples: Hydraulic 0 C = 00ppm = 00% saturation Hydraulic 6 C = 00ppm = 00% saturation ISO 077- Hydraulic fl uid power -- Fatigue pressure testing of metal pressure-containing envelopes -- Test method This Standard describes the method to check the resistance of the hydraulic components with pulsing pressure. It can be applied to all metal components (excluding tubes) subject to cyclic pressure used in the hydraulic fi eld. 0 WATER HYDRAULIC AND LUBRICATG FLUIDS Water Content In mineral oils and non aqueous resistant fl uids water is undesirable. Mineral oil usually has a water content of 0-00 ppm (@0 C) which it can support without adverse consequences. Once the water content exceeds about 00ppm the oil starts to appear hazy. Above this level there is a danger of free water accumulating in the system in areas of low fl ow. This can lead to corrosion and accelerated wear. Similarly, fire resistant fluids have a natural water which may be different to mineral oil. 600 Dissolved water Free water Emulsified - 00% - 7% - 0% - % - 0% Saturation point Parts per million Temperature C Hydraulic oil Gear oil Turbine oil 9 Introduction

22 CONTAMATION MANAGEMENT Water absorber Water is present everywhere, during storage, handling and servicing. MP Filtri filter elements feature an absorbent media which protects hydraulic systems from both particulate and water contamination. MP Filtri s filter element technology is available with inorganic microfiber media with a filtration rating μm (therefore identified with media designation WA0, providing absolute filtration of solid particles to ß x(c) = 000. Absorbent media is made by water absorbent fibres which increase in size during the absorption process. Free water is thus bonded to the filter media and completely removed from the system (it cannot even be squeezed out).

24 Introduction FILTER SIZG DEX CALCULATION CORRECTIVE FACTOR Page Introduction

25 Calculation FILTER SIZG THE CORRECT FILTER SIZG HAVE TO BE BASED ON THE TOTAL PRESSURE DROP DEPENDG BY THE APPLICATION. FOR EXAMPLE, THE MAXIMUM TOTAL PRESSURE DROP ALLOWED BY A NEW AND CLEAN RETURN FILTER HAVE TO BE THE RANGE bar. The pressure drop calculation is performed by adding together the value of the housing with the value of the filter element. The pressure drop pc of the housing is proportional to the fluid density (kg/dm ); all the graphs in the catalogue are referred to mineral oil with density of 0.86 kg/dm. The filter element pressure drop pe is proportional to its viscosity (mm /s), the corrective factor Y have to be used in case of an oil viscosity different than 0 mm /s (cst). Calculation: pc = 0.0 bar (see graphic below) Δp bar MPT 0 - Length * G / Flow rate l/min Filter housings p pressure drop. The curves are plotted using mineral oil with density of 0.86 kg/dm in compliance with ISO 968. p varies proportionally with density. Sizing data for single filter element, head at top pc = Filter housing pressure drop [bar] pe = Filter element pressure drop [bar] Y = Corrective factor Y (see correspondent table), depending on the filter type, on the filter element size, on the filter element length and on the filter media Q = flow rate (l/min) V reference oil viscosity = 0 mm /s (cst) V = operating oil viscosity in mm /s (cst) Filter element pressure drop calculation with an oil viscosity different than 0 mm /s (cst) pe = Y : 000 x Q x (V:V) p Tot. = pc + pe Verification formula p Tot. p max allowed pe = (.00 : 000) x 0 x (6 : 0) = 0.7 bar Filter element Absolute filtration H Series Nominal filtration N Series M Type A0 A06 A0 A6 A P0 P M60 M90 Return filters MF MF 00 MFX 00 MF 00 MFX Maximum total pressure drop ( p max) allowed by a new and clean filter Application Range (bar) Suction filters Return filters Low & Medium Pressure filters High Pressure filters Stainless Steel filters return lines lubrication lines off-line in power systems off-line in test benches over-boost p Tot. = = 0. bar The selection is correct because the total pressure drop value is inside the admissible range for top tank return filters. In case the allowed max total pressure drop is not verified, it is necessary to repeat the calculation changing the filter length/size. Generic filter calculation example Application data: Tank top return filter Pressure Pmax = 0 bar Flow rate Q = 0 l/min Viscosity V = 6 mm /s (cst) Oil density = 0.86 kg/dm Required filtration efficiency = μm with absolute filtration With bypass valve and G / inlet connection Introduction

142 High Pressure filters Clogging indicators Differential indicators Introduction Filter elements are efficient only if their Dirt Holding Capacity is fully exploited. This is achieved by using filter housings equipped with clogging indicators. These devices trip when the clogging of the filter element causes an increase in pressure drop across the filter element. These type of devices can be provided with a visual, electrical or both signals. The electronic model (only available for differential type indicators) with warning signals (7% of clogging) and alarm (clogging). The indicator is set to alarm before the element becomes fully clogged. MP Filtri can supply indicators of the following designs: - Vacuum switches and gauges - Pressure switches and gauges - Differential pressure indicators Suitable indicator types DIFFERENTIAL DICATORS Differential indicators are used on the Pressure line to check the efficency of the filter element. They measure the pressure upstream and downstream of the filter element (differential pressure). Standard items are produced with special connection G / size.

150 Filter elements are efficient only if their Dirt Holding Capacity is fully exploited. This is achieved by using filter housings equipped with clogging indicators. These devices trip when the clogging of the filter element causes an increase in pressure drop across the filter element. The indicator is set to alarm before the element becomes fully clogged. MP Filtri can supply indicators of the following designs: - Vacuum switches and gauges - Pressure switches and gauges - Differential pressure indicators These type of devices can be provided with a visual, electrical or both signals.

152 Introduction Clogging indicators are devices that check the life time of the fi lter elements. They measure the pressure drop through the fi lter element directly connected to the fi lter housing. These devices trip when the clogging of the fi lter element causes a pressure drop increasing across the fi lter element. Filter elements are effi cient only if their Dirt Holding Capacity is fully exploited. This is achieved by using fi lter housings equipped with clogging indicators. The indicator is set to alarm before the element becomes fully clogged. MP Filtri can supply indicators of the following designs: - Vaacum switches and gauges - Pressure switches and gauges - Differential pressure indicators These type of devices can be provided with a visual, electrical or both signals. The electronic differential pressure clogging indicator is also available. It provides both analogical -0 ma ouput and digital warning (7% of clogging) and alarm (clogging) outputs.
