The BA-DME and BAM packages consist of several stages of contaminant removal. Inlet filtration combines to remove bulk water, particles and oil.
The BA-DME and BAM packages consist 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°C (-40°F). 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.
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 well being 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.
