Cartridge filter housing AERO-GUARD series

for compressed airplastic

CO₂ absorber for breathing air and Nitrox applications up to 420 bar The B-AEROGUARD removes approx. two-thirds of the CO₂ content from intake air — for safe, compliant breathing air. An optional control lever, combined with the B-DETECTION PLUS system, allows precise CO₂ reduction adjustment — extending filter life. The B-AEROGUARD reliably reduces CO₂ levels in intake air — ideal for environments with elevated CO₂ concentrations. Its intelligent bypass system routes part of the airflow through the CO₂ cartridge, reducing CO₂ to approx. one-third of the intake level. Integrated air humidification maximizes filter efficiency — even in dry environments. Also available as Nitrox version: reduces CO₂ in the gas mixture to approx. 20% of the membrane outlet value. With the optional adjustable version (used in combination with B-DETECTION PLUS), CO₂ flow can be precisely regulated — helping ensure compliant breathing air while optimizing cartridge service life.
