Medical air

Application

A medical air supply is regarded as a vital part of every
hospital infrastructure and is one of the few medicines that are manufactured on-site. Compressed medical grade air can be used for a wide variety of applications such as anaesthetics, lung ventilation, intensive therapy, pneumatic surgery tools, nebulizers and many more where the quality of the air is vitally important.

The problem

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.

Contaminants present can include:

• Carbon monoxide

• Carbon dioxide

• Water vapor

• Micro-organisms

• Atmospheric dirt

• Oil vapor

• Water aerosols

• Condensed liquid water

• Liquid oil

• Oil aerosols

• Rust

• Pipescale

Parker Domnick Hunter has been introduced Breathing Air Purifiers with CO /CO2 reduction series BA-DME and BAM

BA-DME The Parker domnick hunter BA-DME range consist of Breathing Air Purifiers is ideal for point of use multiple personnel protection at medium flow rates. At the inlet, a General Purpose Filter removes particles, dirt and aerosols, followed immediately by a second stage High Efficiency Coalescing Filter to reduce oil and water content and a third stage Activated Carbon Filter to remove oil vapour and odours. The fourth stage adsorption dryer, reduces the water vapour content of the compressed air (to -40°C pdp) and CO2, NO and NO2 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.

BAC-4015 The Parker domnick hunter BAC-4015 is a fully pneumatic, portable Breathing Air Purifier designed to provide complete protection for up to four personnel. Five purification stages will ensure the highest quality air that is free from particulate dusts, vapours, odours, carbon dioxide (CO2) and carbon monoxide (CO). 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.

BAM range The Parker domnick hunter BAM Breathing Air Purifiers consist of six purification stages mounted on a portable skid for high-capacity multiple personnel breathing air applications. At the inlet, a first stage water separator removes bulk water, followed immediately by a second stage high efficiency coalescing filter to reduce oil and water content and a third stage activated carbon filter to remove oil vapour and odours. The fourth stage adsorption dryer, reduces the water vapour content of the compressed air (to -40°C pdp) and CO2, NO and NO2 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.
Built to exaction standards, the BAM series is engineered to exceed breathing air certified standards. As standard the BAM series are fitted with a CO monitor meaning that there are no high – priced additional expenses or delays to arrange external monitor fitting.
