14 CONTAMINATION 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: - MINERAL 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. - CINEMATIC 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 INDEX 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 INDEX 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. - WORKING 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 CONTAMINATION Whatever the nature and properties of fluids, they are inevitably subject to contamination. Fluid contamination can have two origins: - INITIAL CONTAMINATION Caused by the introduction of contaminated fl uid into the circuit, or by incorrect storage, transport or transfer operations. - PROGRESSIVE CONTAMINATION 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 CONTAMINATION For example rust, slag, metal particles, fi bers, rubber particles, paint particles - or additives - LIQUID CONTAMINATION For example, the presence of water due to condensation or external infi ltration or acids - GASEOUS CONTAMINATION 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 CONTAMINATION 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. CONTAMINATION IN PRESENCE OF LARGE TOLERANCES CONTAMINATION IN 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.

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. - MODIFICATION OF FLUID PROPERTIES (COMPRESSIBILITY MODULE, DENSITY, VISCOSITY) Cause of system s reduction of efficiency and of controllability. It is easy to understand how a system without proper contamination management is subject to higher costs than a system that is provided. - MAINTENANCE Maintenance activities, spare parts, machine stop costs - ENERGY AND EFFICIENCY Efficiency and perfomance reduction due to friction, drainage, cavitation. ABRASION EROSION MEASURING THE SOLID CONTAMINATION 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. HUMAN HAIR (75 µm) DISSOLVED WATER - INCREASING FLUID ACIDITY Cause of surface corrosion and premature fl uid oxidation - GALVANIC COUPLE AT HIGH TEMPERATURES Cause of corrosion MINIMUM DIMENSION VISIBLE HUMAN EYES (0 µm) 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 TYPICAL CONTAMINANT DIMENSION IN A HYDRAULIC CIRCUIT ( 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 allowa to conduct tests and express the measured values in the following ways. Introduction

16 CONTAMINATION MANAGEMENT - GRAVIMETRIC LEVEL - ISO 05 The level of contamination is defined by checking the weight of particles collected by a laboratory membrane. The membrane must be cleaned, dried and desiccated, with fluid and conditions defined by the Standard. The volume of fluid is filtered 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 fluid filtration. ISO 06:999 Cleanliness Code System Microscope counting examines the particles differently to APCs and the code is given with two scale numbers only. These are at 5 µm and 5 µm equivalent to the 6 µm (c) and µm (c) of APCs Cleanliness Code Chart with 00 ml sample volume /9/ Example Code /9/ - CUMULATIVE DISTRIBUTION OF THE PARTICLES SIZE - ISO 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 059 (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) = 50 particles > 6 µm (c) = 00 particles > µm (c) = 5 particles 6 / / Number of particles per ml Over Up to Number of particles per 00ml larger than indicated size New ISO 06 standard µm (c) Old standard ISO Code numbers Introduction

17 CONTAMINATION MANAGEMENT - CUMULATIVE DISTRIBUTION OF THE PARTICLES SIZE - SAE AS 059- and SAE AS 059- Classification example according to SAE AS 059- and SAE AS 059- 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 Dimension of contaminant 6 µm (c) µm (c) 8 µm (c) 8 70 µm (c) >70 µm (c) µm (c) = particles µm (c) = 00 particles 8 µm (c) = 00 particles 8 70 µm (c) = 5 particles > 70 µm (c) = particles Class 6 Class > µm (c) A >6 µm (c) B > µm (c) = particles > 6 µm (c) = particles > µm (c) = 500 particles > µm (c) = 50 particles > 8 µm (c) = 5 particles > 70 µm (c) = particle Class from F to E Table - Class for differential measurement Table - Class for cumulative measurement Dimension of contaminant > µm (c) C > µm (c) D >8 µm (c) E >70 µm (c) F CLASSES OF CONTAMINATION ACCORDING 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. Size Range Classes (in microns) Class Maximum Contamination Limits per 00 ml > µm (c) = 000 particles 5 5 µm (c) = 00 particles 5 50 µm (c) = 50 particles 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.

18 CONTAMINATION MANAGEMENT - CLEANLINESS CODE COMPARISON Although ISO 06:999 standard is being used extensively within the hydraulics industry other standards are occasionally required and a comparison may be requested. The table below gives a very general comparison but often no direct comparison is possible due to the different classes and sizes involved.

The effi ciency of microfi bre and paper fi ltration (ß x(c) ) is defi ned through a lab test called Multipass Test. The effi ciency value (ß x(c) ) is defi ned as the ratio between the number of particles of certain dimensions detected upstream and downstream of the fi lter. 6 / / 6A / 5B / 5C / / 0 / / 09 5A / B / C A / B / C Upstream particles number > X µm (c) = ß x(c) Downstream particles number > X µm (c) 5 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 fi lter prevents particles larger than the pores from continuing in the plant / system. Surface filters are generally manufactured with metal canvases or meshes. Value (ß x(c) ) Efficiency 50% 0 90% % 00 99% % % - DEPTH FILTERING Filters are constructed by fiber interlacing. Such wraps form pathways of different shapes and sizes in which the particles remain trapped when they fi nd smaller apertures than their diameter. Depth fi lters are generally produced with papers impregnated with phenolic resins, metal fi bers or inorganic fi bers. In inorganic fi ber fi ltration, commonly called microfi bre, the fi ltering layers are often overlapped in order to increase the ability to retain the contaminant. Test conditions, such as type of fl uid to be used (MIL-H-5606), type of contaminant to be used (ISO MTD), fl uid viscosity, test temperature, are determined by ISO In addition to the fi ltration effi ciency value during the Multipass test, other important features, such as fi ltration stability (ß stability) and dirt holding capacity (DHC), are also tested. Poor fi ltration stability is the cause of the fi ltering quality worsening as the fi lter life rises. Low dirt holding capacity causes a reduction in the life of the fi lter.

19 CONTAMINATION MANAGEMENT 6 RECOMMENDED CONTAMINATION 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 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. Types of filters: 0/8/5 ß 0(c) >000 9/7/ ß 5(c) >000 8/6/ 7/5/ 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 5 µm. They can be equipped with a magnetic fi lter 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 CONTAINER Container fi lters that are more bulky, but provide easier maintenance of the tank 5//0 ß 5(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 5 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. They are mainly produced with fi ltration depths of 0 5 µm. 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 0.5 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 CONTAMINATION MANAGEMENT FILTER CHOICE PARAMETERS 7 8 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 CONTAMINATION - PROTECTION OF OLEODYNAMIC COMPONENTS SENSITIVE TO CONTAMINATION - PROTECTION OF OLEODINAMIC PLANTS FROM ENVIRONMENTAL WASTE - PROTECTION OF OLEODINAMIC PLANTS FROM CONTAMINATION 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 WORKING 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 (ΔP) 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. WORKING 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 IN 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 CONTAMINATION MANAGEMENT ISO 8 Hydraulic fluid power -- Filter elements -- Determination of resistance to flow fatigue using high viscosity fluid This Standard describes the method for testing the fatigue resistance of the filter elements. The test is carried out by subjecting the filter to continuous flow variations, thus differential pressure, using a high viscosity fluid. ISO 70 Hydraulic fluid power -- Sequence of tests for verifying performance characteristics of filter elements The Standard describes the method for testing the performance of filter 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 filtration). ISO 077- Hydraulic fluid 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 field. 9 Introduction

22 FILTER SIZING The correct filter sizing have to be based on the variable pressure drop depending by the application. For example, for the return filter the pressure drop have to be in 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 in 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 is proportional to its viscosity (mm /s), the corrective factor Y is related to an oil viscosity different than 0 mm /s. Sizing data for single cartridge, head at top pc = Filter housing pressure drop [bar] pe = Filter element pressure drop [bar] Y = Multiplication factor Y (see correspondent table), depending on the filter element size, on the filter element lenght and on the filter media Q = flow rate (l/min) V reference viscosity = 0 mm /s (cst) V = operating viscosity in mm /s (cst) pe = Y : 000 x Q x (V/V) p Tot. = pc + pe Calculation examples with HLP Mineral oil Variation in viscosity Application data: Top tank return filter Filter with in-line connections Pressure Pmax = 0 bar Flow rate Q = 0 l/min Viscosity V = 6 mm /s (cst) Oil viscosity = 0.86 kg/dm Required filtration efficiency = 5 μm with absolute filtration With bypass valve and / inlet connection From the working pressure and the flow rate we understand it should be possible using the following top tank return filter series: MPT, MPH and FRI. Let s proceed with MPT series. The size 0 doesn t achieve the required flow rate, therefore we have to consider the size 00. The final version of size 00 (0, 0, 0, 0 and ) will be then defined in function of the mounting characteristics. pc = 0.0 bar ( see graphic below, considering size 00 with the max available lenght * to get the lowest pressure drop) pe = (.0 : 000) x 0 x (6/0) = 0.7 bar p Tot. = = 0. bar The selection is correct because the total pressure drop value is inside the admissible range for top tank return filters. It is of course possible trying to find a different solution, according to the mounting position or to other commercial need, repeating the previous steps while using a different series or lenght.

26 LMP - low and medium pressure filters are used as process filters to protect pumps, pressure reducers and hydraulic circuits from damage due to oil contamination as per ISO 06. LMP series is available in 5 different sizes: 00, 00, 00, 900 and 950 and a wide range of versions. LMP filters are available with several working pressures suitable for all hydraulic circuits as: - return filters in external tank mounting construction for medium and high flow rates in single and duplex versions - in-line filters for low and medium pressures for off-line applications - in-line process filters for medium pressures, for example, for forced lubrication applications, in single or duplex versions - in-line filters for medium pressures for filtering hydraulic boost circuits - in-line filters as high holding capacity filters on test beds LMP filters are thus specifically designed to be suitable for a wide range of application: from steel plants to mobile equipments, from test benches to naval application, providing the right solution for filtering requirements in all sectors. LMP filters are available in single, manifold and duplex versions. FILTER SIZING For the proper corrective factor Y see chapter at page Low & Medium Pressure filters 0

142 Low & Medium 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. The indicator is set to alarm before the element becomes fully clogged. MP Filtri can supply differential pressure indicators with a visual, electrical or both signals. Suitable indicator types DIFFERENTIAL INDICATORS 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.
