HPT Series Hydrophilic PTFE Membrane Pleated Filters are composed of high-class absolute rated hydrophilic polytetrafluoroethylene membrane and superior polypropylene components. Besides providing high porosity and permeability, PTFE membrane pleated filters provide high dirt holding capacity to minimize change-outs, high flow rate, long service life and low pressure drop.
The construction of PTFE pleated filters are all thermal bonded to make sure no adhesives and their wide chemical compatibility allows them to be available in all common configurations and existing filter housings. Each PTFE pleated filter cartridge is pre-flushed with ultra-pure water and was 100% integrity tested before final assembly.
