CFS-PES-S Series General Grade PES Pleated Filter Cartridges
(331) 215-4119
CFS-PES-S Series polyethersulfone (PES) pleated filter cartridges provide general-purpose micronic and submicronic particulate retention along with superior economy. The PES membrane offers excellent permeability at high flow rates and low pressure drop. Being hydrophilic, cartridges allow for fast and easy wetting in aqueous fluids. The asymmetric membrane structure provides greater contaminant capacity versus traditional membranes. Component materials comply with US FDA and EU regulations for safe use with food and potable water.
