The RAM 4021 series is the unit of choice where specific and accurate measurement of carbon monoxide and oxygen (optional, if specified) are required.
- Continuous carbon monoxide (CO) monitor for compressed air
- Robust, easy to operate design
- Meets OSHA monitoring requirements for grade D breathing air
- AutoCal automatic calibration
- User-adjustable alarm points
- Dry contacts for remote horn and lights
- Internal, case-mounted horn
- LCD display
- NEMA 4× housing
Innovative AutoCal® system makes calibration and maintenance simple. Additional features include alarm relay contacts, user adjustable alarm points, and low flow alarm indicator. All models may be purchased with or without airline filter systems.
The optional 25, 50 or 100 CFM wall mounted filter panels remove dangerous contaminants from supplied air sources and ensure clean, breathable air. The three-stage filter system efficiently removes particulates, oil vapors and hydrocarbons from an air supply. After filtration, the regulator sets the pressure for the respiratory equipment, and the manifold assembly provides multiple outlets for airline hose quick connections.
