Air Filtration

Cynosure Biotech Solutions represents Global Filter in the USA for air filtration utilizing cartridges and/or membranes in single and multi-element vessels. All Global Filter cartridges are manufactured in a clean-room environment to maintain high standards of purity and cleanliness.

Air Prefiltration (Consumable) Cartridges


High Purity Pleated Polypropylene Filter Cartridges provide a high area, 100% polypropylene element for removal of fine or coarse particulate from fluid streams. The pleated depth media is encapsulated in an integral, continuous length, thermally-bonded structure for cleanliness, pressure tolerance, and chemical inertness. Offered in both absolute-rated (up to 99.98% retention) and nominally-rated (90% retention) grades in all end configurations.


High Purity Pleated Borosilicate Microglass Filter Cartridges offer high-efficiency retention of particulate matter from gaseous fluid streams. Favored for its superior retention efficiency, low pressure drop, and greater contaminant loading capacity relative to alternative medias. Suitable for food contact, the FG-Series delivers to the high performance demands in food production.

Sterile-Air Filtration (Consumable) Cartridges


High Purity Bio-Reduction Grade PTFE Filter Cartridges, with expanded polytetrafluoroethylene (PTFE) membrane, provide reliable high-LRV reduction of micro-organisms in bio-process applications where the high cost of a fully-validated pharmaceutical-grade cartridge is not required. Whether it’s fermentation feed air, compressed gas, or a process venting application, the BRPTFE offers a high-flow, high-capacity membrane filter with exceptional hydrophobicity. The superior flow rate allows for economical costs of system design and operation. Proven 7.4 LRV retention of aerosolized bacteriophage provides reliable bioburden reduction and prevention of process contamination. Tolerates multiple sterilization cycles by autoclave or in-situ steaming. 100% integrity tested in production.


High Purity Pharmaceutical Grade PTFE Filter Cartridges, with expanded polytetrafluoroethylene (PTFE) membrane, provide optimized filtration performance in sterile air/gas filtration and venting applications. The single-layer PTFE membrane, with over twice the hydrophobicity of polypropylene or PVDF, is the best choice to prevent water intrusion and resulting microbial growth. Each PPTFE cartridge is integrity tested during manufacturing and is supported by a validation guide for regulatory compliance. PPTFE elements are fully validated as sterilizing grade filters in liquids in accordance with HIMA and ASTM F838-05 guidelines and in gases through full retention of the MS2 phage in an aerosol challenge.

Stainless Steel Housings

Fermenter Air and Hygienic Atmospheric Vent Housings

Sanitary and process industrial designed housings constructed of 316 stainless steel to handle a wide range of air flowrates and to accept filter cartridges in -222, and -226 style end configurations.  When used in conjunction with prefilters and sterile air cartridges, will keep fermenters free of unwanted contaminants.  Pressure vessel stamp option for steam in place capability.
