|Sterilizing-Grade Aervent® Filters (Milliporesigma)|
|What is the difference between Aerex and Aervent?||Aervent cartridges have a 0.2µ PTFE membrane and are used in pharmaceutical applications where it is critical to use a phobic filter that has proven bacterial and viral retention capabilities. Common applications for Aervent are fermentation air applications, bioreactor inlet and outlet filtration and sterile process gases. Aervent filters have a liquid bacterial retention claim as well as a virus aerosol retention claim.
Aerex filters also have a 0.2µ PTFE membrane but they do not come with a liquid bacterial retention claim. Common applications for Aerex include bulk intermediate manufacturing and non-pharamaceutical applications such as industrial fermentation. Aerex filters do have a virus aerosol retention claim.
|Can I mount my tank vent filter horizontally?||Millipore recommends that you mount your vent filter vertically because it will facilitate the draining of any condensate that may collects in the bottom of the housing. If condensate builds up in the housing, it can cause part of the filter to becomes wet which will prevent air from passing through.|

The 0.2 µm hydrophobic Aervent® polytetrafluoroethylene (PTFE) membrane provides sterility assurance, high flow rates and throughput. The Aervent® membrane contributes to clean processes due its non-fiber releasing properties.
Hydrophobic Aervent® cartridge filters provide high throughput with minimal differential pressure. Cartridges are robust, strong, resilient and are designed to withstand multiple steam-in-place cycles.
Filters with hydrophobic Aervent® membrane are designed, developed, and manufactured in accordance with a Quality Management System approved by an accredited registering body to an ISO® 9000 Quality Systems Standard and are shipped with a Certificate of Quality. Each cartridge filter is integrity tested during manufacturing.
For traceability and easy identification, each filter is labeled with the product name, lot number and serial number.
Multiple Formats Available
Hydrophobic Aervent membranes are available in two device formats, one pore size, and multiple configurations that vary by filtration area and type of inlet/outlet connection.
- Opticap® XL disposable capsule filters
- Cartridge filters
Aervent® hydrophobic filters will remove particles and microorganisms from gases and liquids. The sterilizing-grade rating is based on HIMA liquid bacterial retention challenge. In gases this filter will remove contamination down to 0.01 µm. Cartridge filters will also sterilize alcohol streams.
