Durable, Corrosion Resistant
Design for Liquid Applications
The Pall range of non-metallic single cartridge housings offers an economical answer to low flow requirements. Non-metallic housings are available with polypropylene heads and a choice of polypropylene or SAN bowls to suit a range of chemical applications. Filter assemblies should not be used with fluids incompatible with the materials of construction. These industrial designed housings are ideally suited for use with low flows where a metallic housing is not required. - Cost effective alternative to stainless steel in corrosive fluid applications
- Accepts 20 in. (50.8 cm) DOE or Pall M5 (Code 5) style cartridge
- Fixed guides in head and shell ensure proper alignment and seating of cartridges
- Manufactured from materials which are listed for Food Contact Applications in Title 21 of the U.S. Code of Federal Regulations

Housing Differential Pressure vs. Liquid Flow Rate

Unit conversion: 1 bar = 100 kpa
For liquids other than water, multiply differential pressure by the specific gravity of the fluid.


1Housing head has mounting bosses, which accept self-tapping screws for attaching a bracket to the housing.
2Dependent upon cartridge selection, fluid viscosity and allowable pressure drop.
