Filter Housing for Individu HYDAC inline filters are designed for the toughest applications in process technology. They separate solid particles of all types very effectively. Numerous designs and filter materials enable optimal adaptation to the filtration application and the process conditions which are present. We manufacture quality-tested single and duplex filters in stainless steel and corrosion-protected steel. Special materials and special coatings can be used on request. Models with vertical filter elements or suspended contamination retainers are also available as options. Inline Filter PFL / PFM Universal filters in stainless steel for pressures up to 40 bar, temperatures up to 200 C and flow rates up to 140 l/min. Connection size: straight pipe thread G 1. Wide range of applications due to wide range of sizes Filter materials: slotted tube, wire mesh, Chemicron metal fibre, coiled meltblow candles Special feature: No tool required to change the element. Inline Filter PRFL Comprehensive inline filter range for flow rates up to 25,000 l/min. Housing material: spheroidal cast iron EN JS 1,030 or carbon steel 1.0038 or totally in stainless steel. Flange connections from DN 50 and above. The pressure range, depending on the size is PN 25 or PN 16 bar. The elements are as for the PRFLD series. Stainless Steel Pressure Filter EDFR / EDFA Change-Over Inline Filter PRFLD Highly robust pressure filter in stainless steel for handling aggressive fluids and extreme operating conditions up to 400 bar and 400 C. Filter materials: wire mesh, Chemicron metal fibre, Betamicron inorganic mesh packs. Connection options: straight pipe thread G 3 /4, 1 1 /4, 1 1 /2. Stainless Steel High Pressure Filter MPSSF / HPSSF / ACSSF Customized Solutions If no standard product is suitable for your application, we also develop filter housings and elements to customer specification. To avoid shutting down the system when changing the element, change-over filters provide the solution, whereby one housing is filtering and the other is in reserve. The change-over occurs by means of a ball valve or butterfly valve with hand-wheel. The special design of the change-over device prevents both sides being shut-off at the same time. The filter housing can be fitted with slotted tubes or filter candles in wire mesh or Betamicron inorganic mesh packs. This stainless steel high pressure filter is similar in design to the EDFR filters. There are three pressure ranges available: 450, 700 and 1,000 bar. The maximum operating temperature is 100 C. Filter materials: wire mesh, Chemicron metal fibre, Betamicron inorganic mesh packs. Types of connection possible: BSP or NPT threads 1 /4, 3 /8, 1 /2, 3 /4, 1, 1 1 /4, 1 1 /2 ; SAE-4 to SAE 24.

Inline Filter PRFLK / PRFLKD with Coiled Candles: Simple Change-Over Filter Original HYDAC Accessories for Safe, Long-Term Operation To monitor contamination in the filter elements we provide visual and visual-electrical clogging indicators for all inline filters. All indicators work on the principle of differential pressure measurement and are self-setting. By using coiled filter candles in polypropylene or polyester, a very high contamination retention capacity is achieved. For continuous processes, each size is also available as a duplex filter. Filter areas, pressure drops and service life can be optimized for the greatest economy, owing to numerous housing sizes and nominal widths from DN 50 and above. Accessories which have been specially developed for our filters, such as seal kits, cover plate lifting devices, vent valves and drain valves, simplify operation and ensure a long service life. Screen Basket Filter PRFS / PRFSD: Simple Change-Over Filter Filters for Hydraulics and Lubrication Screen basket filters are used mainly as coarse filters or preliminary filters. In contrast to the inline filters PRFL and PRFLD, flow through the filter element is from in to out. The separated contamination stays in the stainless steel basket and can be disposed of quickly and easily. Nominal sizes available from DN 50 and above. Materials: Carbon steel 1.0038 or stainless steel 1.4571 (316 Ti) HYDAC offers a comprehensive filter range, specially coordinated for hydraulics and lubrication in construction, size and pressure range and with elements to suit various operating fluids.

Filter Elemen The core of a filter is the filter element. This is where the results of many years research and development are best demonstrated. A wide range of filter materials and element designs can be used to solve the widest variety of filtration tasks. Most of the filter materials can be cleaned which eliminates the substantial costs of re-purchase and disposal. Wire Mesh Slotted Tube Re-usable, cleanable filter mesh pack. Material: 1.4401 (316) 25; 40; 60; 100; 150; 200; 250; 500 µm Chemicron Metal Fibre Slotted tubes consist of profiled wire which is welded around a support section. The filtration rating is determined by the distance between the wires. Their extremely robust construction means that slotted tubes can be cleaned as often as required. Material: 1.4435 (316 L) 50; 100; 150; 200; 300; 500; 1,000; 2,000; 3,000 Stainless Steel Screen Baskets Chemicron is a cleanable, metal fibre, deep filter medium which has high contamination retention capacity and excellent retention rates due to its three-dimensional structure. It also has excellent fluid and temperature resistance up to 400 C due to the austenitic material, 1.4404 (316 L). 1; 3; 5; 10; 20; 25; 30; 40; 60; 100 µm (absolute) Betamicron Inorganic Mesh Packs Our screen baskets are ideal for longterm operation due to their robust design. Once the contamination has been removed and the basket has been briefly high pressure cleaned, the screen basket is ready to use again. The stainless steel baskets can be purchased as slotted tube and perforated plate versions. Slotted tube 50, 100, 150, 200, 300, 500, 1,000, 2,000, 3,000 µm Perforated plate: 3, 4, 5, 10 mm This disposable filter material has an excellent contamination retention capacity at low purchase costs. 3; 5; 10; 20 µm (absolute)

nts. Elementary and Individual. Coiled Filter Candles in Polypropylene or Polyester This deep filter material consists of 100 % meltblown polyester (PBT) or polypropylene (PP) fibre in a variety of thicknesses and porosities. A special winding technique produces an asymmetric deep filter matrix where the fibre layers become finer in the direction of filtration. This makes possible an extremely high contamination retention capacity with low pressure drop. 1, 3, 5, 10, 20, 40, 50, 70, 90, 100, 120, 150 µm (absolute) Maximum operating temperature: 80 C for polypropylene elements 100 C for polyester elements Defining Filtration Efficiency In order to be able to compare the different filter materials in filtration technology, the separation rate ß x has been defined. This value indicates the ratio of quantities of particles above a certain size before and after the filter element. number of particles > x µm before the filter ß x = number of particles > x µm after the filter x = particle size in µm Absolute Filtration Rating for Betamicron inorganic mesh packs, coiled candles and Chemicron metal fibre A ß x value of 100 (ß x = 100) corresponds to a separation rate of 99 %. During this test the filter must retain at least 99 % of the particles larger than the stated micron rating and up to a given differential pressure. This denotes absolute filtration. The rates given in the brochure are determined by the multi-pass test, carried out on the HYDAC test rig, in line with ISO 4572 (Multi-pass test for the determination and proof of the filtration performance, extended to finest filtration). Nominal Filtration Rating for wire mesh and slotted tubes No ß x values have been determined for these elements. The mesh width or slot width of the filter material concerned is given as the filtration rating. Standardised test procedures for our filter elements ensure consistently high filtration efficiency. The separation rate and contamination retention capacity is tested on our multi-pass test rig. Final testing on the bubble-point test rig. Only perfectly manufactured filter elements leave our factory. High Quality as Standard Quality takes priority at HYDAC, and is guaranteed by permanent monitoring during the manufacturing process and systematic laboratory tests. Rigorous goods-in inspection ensures that only perfect materials are used in production. In addition to numerous international approvals and registrations, HYDAC quality management is certified according to DIN EN ISO 9001 your guarantee of the consistently high quality level of our products.
