BA-DME Breathing Air Purifiers

Hazardous vapors, gases and fumes can be released at various stages within manufacturing applications. Whether the risk is from noxious fumes, particulate or contamination from a compressed air system, effective respiratory protection for the user is essential.

In compressed air fed systems, ambient air is drawn into the compressor, therefore any contaminants present in the ambient air, plus those introduced by the compressor itself, will be present unless removed by a purification system.

The Parker Domnick hunter BAC-4015 is a fully pneumatic, portable breathing air purifier designed to provide complete protection for up to four personnel.

At the inlet, a high efficiency coalescing filter reduces oil and water content, an activated carbon filter then removes oil vapour and odours.

The third stage of purification is an adsorption dryer that reduces the water vapor content of the compressed air (to -40°C pdp) and CO2 levels to below the legal permissible limits.

Downstream of the adsorption dryer, a catalyst converts carbon monoxide to carbon dioxide, again, to below the legal limits. A final dust filter captures any particulates carried over from the adsorption materials.

The flow rate is easily adjustable from a pressure regulator and monitored by inlet/outlet pressure gauges on the front facia. The BAC-4015 is housed in an extremely strong and robust lockable case for total security.
