Filter Cartridges: Materials of Construction

The most common material of construction for our filter cartridges, polypropylene offers a broad fluid compatibility, can be used at relatively high temperatures and satisfy various FDA regulations related to food, beverage and pharmaceutical processes.  Not all "polypropylene" cartridges are the same, the manufacturing technique  and the design of the cartridge directly affect the particle loading and differential pressure for a given flow rate.  The Eaton LOFTREX filter cartridges are made with a melt blown process to provide varying densities for increased particle retention whereas other versions utilize multiple layers material to increase retention capacity.  The Eaton LOFPLEAT design combines multiple pleated layers to increase available surface area.

This is the material used for our membrane filter cartridges, the manufacturing technique enables increased surface area.  The PES used for the Eaton LOFMEM filter cartridges satisfies relevant FDA specifications and these are commonly used for beverage and pharmaceutical applications.
