NFH Low Pressure Filters

Transcription

1 PPLICTIONS NFH Low Pressure Filters Pressures to 360 psi Flows to 450 gpm Water Removal Capability 4 Ports HYDC NFH In-line Return Filters are designed for use on hydraulic power units, machine tools, plastics injection molding equipment, Pulp & Paper manufacturing systems and hydraulic test equipment. These filters are designed to be directly mounted in the return line for filtration of solids from hydraulic fluids. Modular design makes these filters especially suitable for high flow applications. PRODUCT FETURES The NFH filter assembly has a ductile iron head and lid with steel housing. Threaded ports for clogging indicators are standard. ll models have an air bleed valve (vent) installed in the lid. Single large element with no leak points for highest efficiency and dirt capacity Lid with swing bolts for fast servicing without tools Drain port (Far side) SE 12 (3/4 ) Clogging Indicator for local and/or remote signals FILTER ELEMENT HYDC NFH Filters are available with disposable Betamicron BN3HC elements having 250 psid collapse pressure and absolute ratings of 3, 5, 10, and 20 micron. HYDC NFH Filters are also available with cleanable wire screen (W/HC) elements having a 250 psid collapse pressure and nominal ratings of 25, 74, and 149 micron. For applications which do not require fine filtration, disposable HYDC (P/HC) Polyester elements may be selected. Polyester elements have 145 psid collapse pressure and nominal ratings of 10 and 20 micron. quamicron (M) elements are available for applications specifically requiring water removal. These elements have a 40 micron absolute rating and a 145 psid collapse pressure. Betamicron quamicron (BN/M) Combination Elements are available for applications in which control of significant levels of water and dirt ingression, by the same filter is desired. These combination elements are available in 3µm and 10µm absolute ratings and they remove a large amount of water from the system. ll filter media is structurally supported to achieve high flow fatigue resistance. Proper support of the filter media also provides high Beta Ratio values (particle removal efficiency) even at high differential pressures. The efficiency of many competitive elements drastically deteriorates as the element clogs and differential pressure increases over the life of the element. High quality epoxy adhesive is used to bind the end caps to the media and to bond the seam of the media. ll elements available for HYDC NFH filters have the bypass valve built into the filter element. s a result, a new bypass valve is provided each time the element is changed, making it less likely that a bypass valve will stick open, jam, or fail through fatigue.

To determine Clean P for manifolds with multiple housings, multiply the Clean P curve value by the percentage values in the table.
