Details & Features
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.
Options
- Various hose connectors & couplings (ND 25, 32, 40, 60, 100 mm)
- Intake fittings, safety valves & angles for membrane / Nitrox systems
- Mounting brackets & sensor retrofit kits
- Replacement filter cartridge incl. disinfectant tablets
- Accessory kits for older compressor models
Scope of delivery
- Intake pipe (matching connection hoses to be ordered separately — see "Options")
- Water tank, 60 l (for B-AEROGUARD DUO version — 2 × 60 l water tanks)
- Filter cartridge; contents: 8.3 kg special CO₂ absorber
