INTERNORMEN Cartridge Filters

PES Pleated Membrane Cartridges, ensure an extended service life, cost-effective & suitable for a variety of aqueous based fluids, e.g. for chemical filtration, deionized water systems, for general use water filtration & liquid clarification. Special designs for food & beverage applications & the electronic industry are also available. Water Service Grade PES Cartridgesare cost-effective alternatives to General & Electronic Grade Cartridges for a variety of aqueous based fluids. Water Service Cartridges are manufactured from an inherently hydrophilic PES-membrane. The cartridge offers excellent flow characteristics, extended service life, and broad chemical compatibility.
