|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.
Aerex® 2 hydrophobic cartridge filters provide high flow rates at low pressure differentials. These cartridge filters are manufactured using PTFE membrane and are 100 % integrity tested to assure optimal sterilizing performance. Each filter lot must also pass rigorous stress testing before release.
Designed to remove bacteria and viruses from moist gas streams, the filters are ideally suited for use in bulk fermentation applications.
