Breathing Air Purifiers

Comply with OSHA Grade D, NFPA-99, CSA Z180.1-00, European Pharmacopoeia and other International Breathing Air Standards

Why purify compressed air?

In recent years, employers have become increasingly aware of their responsibility to comply with International Breathing Air Standards. The standards define the quality of breathing air that must be provided to operators working in contaminated environments. Contaminants frequently present in compressed air that threaten the wellbeing of breathing air users are;

  • Fumes
  • Oil
  • Vapours
  • Gases
  • Solid particles
  • Micro-organisms

For compressed air to be suitable for breathing air applications, it must be properly purified to ensure that it meets the relevant Breathing Air Standard.

What type of purifier should be used?

With a wide variety of purification products available, ranging from a simple respirator offering basic protection against low levels of dust particles to self-contained breathing apparatus it is essential that the inhalation risks be fully assessed and a suitable purification product selected. Parker domnick hunter breathing air purifiers are designed to offer the user protection against some or all of the contaminants that may be present in a compressed air fed breathing air system. Cleveland Compressed Air Services provides a complete range of breathing air purifiers designed to match the specific needs inherent when breathing from a compressed air supply.

How do you know the quality of breathing air required?

Whatever the application, the quality of the compressed air used for breathing air applications is detailed in International Breathing Air Standards. The applicable standard for the country of use will not only detail the maximum allowable levels of contaminants but also give an indication of the selection criteria for protection devices. If doubt exists about the potential of a possible contaminant then steps must be taken to either monitor the air quality or install a suitable purification device to ensure compliance with the standard.

Where would you use a Parker domnick hunter breathing air purifier?

Many applications exist, ranging from the life threatening environments of fire fighting, hazardous shot blasting and paint spraying operations, to critical, medical and hospital air requirements.

Based on the quantity of breathing air required, the following solutions are available:

  • BA-DME Series (Up to 176 SCFM)
  • BAM Series (240 – 800 SCFM)
  • BA-2010 Portable Series

BA-DME Series Breathing Air PurifiersBA-DME Series Breathing Air Purifiers

The Parker domnick hunter BA-DME Breathing Air Purifier System consists of several stages of contaminant removal. The use of adsorption materials, namely activated desiccant and carbon removes water vapour and oil vapour/odours respectively. The desiccant material is contained in a pressure swing adsorption dryer that delivers a constant pressure dewpoint of -40°F (-40°C). Downstream of the desiccant dryer, a catalyst converts carbon monoxide to carbon dioxide by catalytic conversion. A final dust filter captures any particulates carried over from the adsorption materials.

The BA-DME Breathing Air Purifier System removes the following contaminants: solid particles, oil mists, oil vapours, odours and fumes, water mists, water vapour, carbon monoxide and carbon dioxide.

Hospital and Medical Air Quality

A medical air supply is a vital part of every hospital infrastructure and is one of the few medicines that is manufactured on-site.  Parker domnick hunter BA-DME and BAM Breathing Air Purifier Systems provide integrated filtration and adsorption stages to deliver the air quality required for medical applications.  Parker domnick hunter Breathing Air Systems have been tested to the European Pharmacopoeia Medical Air Standard, which is more stringent than OSHA Grade D standards.

Features & Benefits

  • 6 purification stages
  • Use with any compressed air supply
  • Integrated CO Monitor
  • Electrical supply required
  • Exceeds international breathing air standards
  • Energy management system (Dewpoint Depending Switching (DDS)) – Optional
  • CO and CO2 removal

BAM Series Breathing Air Purifiers

Parker domnick hunter’s BAM Breathing Air Purifier System consists of several stages of contaminant removal. Inlet filtration combines to remove bulk water, particles and oil. The use of adsorption materials, namely activated desiccant and carbon removes water vapour and oil vapour/odours respectively. The desiccant material is contained in a pressure swing adsorption dryer that delivers a constant pressure dewpoint of -40°F (-40°C). Downstream of the desiccant dryer, a catalyst converts carbon monoxide to carbon dioxide by catalytic conversion. A final dust filter captures any particulates carried over from the adsorption materials.

The BAM Breathing Air Purifier System removes the following contaminants: solid particles, oil mists, oil vapours, odours and fumes, water mists, water vapour, carbon monoxide and carbon dioxide.
