Breathing Air Purifiers
We supply a range of breathing air purifiers:
High pressure breathing air purifiers incorporating CO and CO2 removal.
This high pressure breathing air purifiers (HPBAP) can be used with most high-pressure compressed air systems up to 350 bar g (5075 psi g).
Purification requirements of high pressure breathing air are basically the same as those for low pressure although the need to dry air down to very low dewpoints is essential to prevent freezing of valves and other downstream equipment.
The dh range of high pressure breathing air purifiers offers complete protection against carbon monoxide (CO) and carbon dioxide (CO2). All purifiers in the range are designed for easy installation, operation and maintenance with simple in-line connections. Integral safety devices are standard and provision is made for air quality sampling.
These purifiers utilise two main stages of air treatment each with specific functions: Stage 1 Grade AA - High efficiency coalescing filter; Stage 2 is a composite cartridge, which has five individual processes.
- Full CO and CO2 Protection
- Long life filter cartridges
- Integral safety devices
- Provision for air quality sampling
dh has larger flow breathing air systems available, similar in operation to the BA-2010. These units are stationary in design to provide a continuous supply of breathable air. Five stages of treatment provide compressed air one million times cleaner than we normally breathe. Stage 1 is Grade AA, followed by stage 2, an absorption bed of activated carbon (AC), stage 3 is a twin tower heatless regenerative air dryer, stage 4 is a catalyst and stage 5 is a final filter (AR) for "polishing" the air.
Larger flow breathing air purifiers are available as standard packages or can be designed to suit specific requirements - please ask for details.
Skid and trailer mounted kits are also available.
- CO and CO2 removal
- Visual warning of system failure
- Low pressure alarm contacts
- Flow limited control device prevents overflowing unit with too much air
- Hours run meter
- Systems pressure gauge
- CO monitor alarm is available (extra)
The domnick hunter BA-4350 and BA-1400 portable breathing air purifiers provide high quality breathable air from a normal compressed air supply.
Combining high efficiency and activated carbon filtration stages, both units are housed in compact, weather proof, impact resistant cases which can supply air for up to four users. The BA-1400 also includes a water separator for the removal of bulk liquids and is available with an optional CO monitor.
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:
- Solid particles
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. 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. As the world leader in filtration and purification of compressed air, domnick hunter offers unrivalled experience in the design and manufacture of air treatment equipment. With domnick hunter breathing air purifiers in constant use worldwide, protecting lives in virtually every type of industry and the commitment to continuous research and development, domnick hunter 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 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.
- High pressure cylinder filling
- Shot blasting
- Tank cleaning
- Pharmaceutical Manufacturing
- Spray painting
- Medical and hospital air
- Offshore / Marine
- Asbestos removal
