Full description

Pleated membrane cartridge filters from CHM® offer the ultimate in product safety and purity for absolute filtration with pore sizes from 0.05 to 5 micron (depending on the media).
Available in the main membranes PTFE, Polyethersulfone (PES), Nylon 66 and PVDF for maximal chemical compatibility.
CHM® pleated membrane filters are ideal for a wide range of high purity and final filtration applications.

CHM® Nylon filter cartridge

CHM® hydrophilic nylon pleated cartridge filter are uniquely constructed for superior performance with Nylon media. The pleat technology maximizes the useful surface area of the filter while maintaining proper flow paths between media pleats. The membrane offers broad chemical compatibilities & contains no surfactants. This CHM® cartridge filters are manufactured with nylon and polypropylene support media, both materials are chemically inert non-shedding and biologically safe according to FDA, USP and EEC requirements for pharmaceutical and food contact use. Thermoplastic sealing technologies are used in the cartridge construction eliminating the need for potentially contaminating adhesives.

Features:
· Better performance for high temperature-resistance, acid and base resistance
· Hydrophilic membrane with high flow
· Non-fiber releasing according to pharmaceutics and food industry requirements
· 100% integrity tested
· Flushed with ultrapure water

Applications:
· Pharmaceutical
· Food and Beverage
· Semiconductor
· Pre-filtration

CHM® PTFE filter cartridge

CHM® hydrophobic PTFE pleated cartridge filters are uniquely constructed with polytetrafluoroethylene media. PTFE membranes offer broad chemical compatibility with minimal extractables in a wide range of fluids and applications and contains no surfactants. The inherently hydrophobic PTFE membrane is ideally suited for the filtration of compressed air and other process gases. The pleat technology maximizes the useful surface area of the filter while maintaining proper flow paths between media pleats. These CHM® cartridge filters are manufactured with PTFE and polypropylene support media, both materials are chemically inert non-shedding and biologically safe according to FDA, USP and EEC requirements for pharmaceutical and food contact use. Thermoplastic sealing technologies are used in the cartridge construction eliminating the need for potentially contaminating adhesives.

Features:
· Better performance for high temperature-resistance, acid and base resistance
· Hydrophobic membrane with high flow
· Low pressure drop, long service life, high flow rate
· 100% integrity tested
· Non fiber-releasing

Applications:
· Fermentation tank
· Vent filter of hold tank
· Semiconductor
· Gas purification
· Acid, solvent and base filtration

CHM® PVDF filter cartridge

CHM® hydrophobic PVDF pleated cartridge filters are uniquely constructed with polyvinylidene fluoride media. PVDF membranes offer broad chemical compatibility with low extractable levels, high protein binding and high chemical inertness. The pleat technology maximizes the useful surface area of the filter while maintaining proper flow paths between media pleats. These CHM® cartridge filters are manufactured with PVDF and polypropylene support media, both materials are chemically inert non-shedding and biologically safe according to FDA, USP and EEC requirements for pharmaceutical and food contact use. Thermoplastic sealing technologies are used in the cartridge construction eliminating the need for potentially contaminating adhesives.

Features:
· Hydrophobic membrane with small adsorption
· Reinforced PVDF filter membrane and deflector layer
· 100% integrity tested
· Flushed with ultrapure water

Applications:
· Pharmaceutical
· Food and Beverage
· Petrochemical
· Pre-filtration
· Oxidizing gas and liquid

CHM® PES filter cartridge

CHM® hydrophilic PES pleated cartridge filters are uniquely constructed with polyethersulphone media. PES membranes offer broad chemical and contains no surfactants, it allows easy integrity testing for all applications where daily control is required. The pleat technology maximizes the useful surface area of the filter while maintaining proper flow paths between media pleats. These CHM® cartridge filters are manufactured with PES and polypropylene support media, both materials are chemically inert non-shedding and biologically safe according to FDA, USP and EEC requirements for pharmaceutical and food contact use. Thermoplastic sealing technologies are used in the cartridge construction eliminating the need for potentially contaminating adhesives.

Features:
· Hydrophilic membrane with high flow
· No-fiber releasing according to pharmaceutics and food industry requirements
· 100% integrity tested
· Flushed with ultrapure water
· Excellent performance of chemical compatibility

Applications:
· Pharmaceutical
· Food and Beverage
· Petrochemical
· Biological industry
· Chemical

CHM® Stainless Steel Filter Housing

Sanitary stainless steel filter housings are specifically designed for liquid and air/gas filtration applications of the bio-pharmaceutical industry, food and beverage. Manufactured in AISI 316 L. Typical application areas for stainless steel housings include bioreactors, autoclaves, freeze dryers and process tanks.
