CBAS (Compressed Breathing Air Systems)

Description

FSG Compressed Breathing Air Systems (CBAS) purify compressed air to meet or exceed OSHA and CSA requirements.

The CBAS removes oil mist, aerosols, particulates, moisture, carbon monoxide and hydrocarbon vapors commonly found in compressed air streams.

Principle of Operation

The FSG CBAS design is comprised of five purification stages.
The first stage consists of a dual layer prefilter, which removes particulate and oil contamination.  The filtered air then passes through a desiccant dryer for moisture and odor removal.  The dryer ensures the integrity and purification efficiency of the catalytic converter.

The catalytic converter, which eliminates Carbon Monoxide, is the next stage of purification.

The fourth stage is an activated carbon bed for the removal of trace hydrocarbon vapors and objectionable odors.  The final stage is a high efficiency particulate afterfilter.

What sets FSG apart

respirator manifold assembly Respirator Manifold Assembly

OSHA / NIOSH approved respirator manifold assembly includes:

  • Air shutoff and safety relief valves
  • Pressure adjusting regulator
  • Manifold block standard with (2) non-compatible disconnects and protective covers
stainless steel airstream moisturizer Stainless Steel Airstream Moisturizer

Designed to rehumidify compressed airstream prior to entering worker respirators.

Unit provides humidity level adjustment and sight window to view water level.

Dual units with isolation valves are available to allow service without interrupting production.

digital display Digital Display Dew Point Demand System

Provides maximum energy efficiency and matches purge rate to moisture loading (prevents breathing air from being over dried).

Ceramic sensor reads dew point between –148°F to +68°F while being resistant to liquid water damage.

CO Monitor Carbon Monoxide Monitor

Unit provides continuous monitoring of carbon monoxide in compressed breathing air stream.

CO monitor includes an audible alarm, and adjustable set points for both OSHA and CSA standards.

Chemical cell or MOS designs available.
