HIGH PRESSURE FILTERS FPK2 Max Flow: gpm (9 lpm) FPK2 In-Line Cartridge Filters Working Pressures to: Rated Static Burst to: Flow Range to: 69 psi 42, kpa 42 bar 913 psi 63, kpa 63 bar gpm 9 lpm Features The FPK2 is built to withstand pressures upwards of 6 psi (42 bar). It features a cast iron head and cold-extruded steel housing for ultimate strength and durability. This filter meets the HF2 in-plant automotive specification. Bypass options include 87 psi/6 bar bypass, bypass with reverse-flow check valve, or no bypass. Take advantage of our mix and match system of in-stock heads, housings and cartridges, so you can get exactly what you need. You can also choose the media type and configuration that s best for your application. All FPK2 filters contain Synteq, Donaldson s exclusive synthetic fiber media formulated especially for hydraulic filtration.

If you re filtering petroleum-based oil, filters with seals made of Buna-N are appropriate for most applications. If you re filtering diester, phosphate ester fluids, water glycol, water/oil emulsions, and HWCF over F/83 C, use filters with seals made of fluorocarbon, such as Viton from DuPont Dow Elastomers, or Fluorel from 3M Company. Donaldson "high collapse" filters, with their steel end caps and wire-backed media, are rated to withstand up to 3 psi/ 2,7 kpa before collapsing. The fluorocarbon seal/high collapse filters also use epoxy potting and media seam seals for added chemical compatibility. Viton and Buna-N registered trademarks of E. I.

All Donaldson DT filters are potted with epoxy-based adhesives. Standard collapse DT designs are double wire-backed using epoxy-coated steel mesh for maximum pleat support and dirt capacity. High collapse designs are double wire-backed using stainless steel mesh. High collapse designs are also potted into machined aluminum endcaps for greater filter integrity in critical applications. Viton seals are standard on all Donaldson DT filters. Viton is aregistered trademark of E. I. DuPont de Nemours and Company. Hydraulic Filtration 3
