Absolute (99% ^), Final Filter
Pleated PTFE Membrane Cartridge
The Proflow II Pharmaceutical Aerosol Bacterial Retentive (ABR) cartridge(0.2μm) is validated to produce sterile air utilizing a bacterial aerosol challenge (See the Validation Guide for the test protocol). This methodology best emulates the actual bacteria removal action of the filter in use as a hydrophobic vent. Proflow II ABR exhibits some of the highest air flow rates available among sterilizing grade air filters that utilize pleated expanded PTFE membrane. Users who expect the ultimate in flow rate performance for tank venting and sterile air supply will find the Proflow II ABR to be their filter of choice.
