PES Cartridges are made up of Poly Ether Sulphone with uniform pore distribution to ensure maximum performance in bacterial retentions. its upstream &downstream polyester support ensures complete resistance to pressure shocks. Polyethersulphone membrane is hydrophilic in nature, hence it allows easy integrity testing for all applications where daily controls are required. The membrane possesses broad chemical compatibilities & contains no surfactants. PES Cartridges are produced in controlled environments & under stringent production conditions that ensure filter quality & cleanliness. These are assembled integrally by thermo welding. This process minimizes the presence of oxidization of substance & yield a durable filter cartridge suitable for extended use. Further, this can be sanitized by chemical agents or by inline steaming. PES and polypropylene, the unique two materials used in cartridge manufacturing are chemically inert, not shedding and biologically safe according to F.D.A., USP and EEC requirements for pharmaceutical and food contact use. The filtration area of each cartridge is as high as 0.7 m2. Therefore, it offers a high flow rate, low-pressure drop & long service life.
