Gas or vent filters containing hydrophobic membrane are commonly used as air vents throughout biomanufacturing to maintain near-ambient pressure in processing tanks and closed systems. These filters act as a barrier, preventing both the entry of adventitious microorganisms and the release of product aerosols.
Generally, the main considerations for gas filtration include filter position, sizing, sterilization processes, and integrity testing practices. There are stringent regulatory expectations for critical gas or vent filters, which include confirming the integrity of filters on sterile holding tanks and filling machines, and after steam-in-place sterilization or use.
We offer gas and vent filters in both cartridge and single-use capsule formats for different applications. Each sterilizing-grade filter is integrity tested during manufacturing and is supported by comprehensive documentation for compliance with regulatory requirements.
