We supply a range of breathing air purifiers:
 HPBAP Series
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
 BA-2025 and BA 2030
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)
BA4350
The dh BA-4350 is a portable
breathing air purifier, designed to provide
high quality breathable air from a normal
compressed air supply.
The unit utilises two high efficiency
purification stages combined together in a
compact, weather proof, impact resistant
housing to meet international breathing air
standards.
- No electrical supply required
- Tough impact and chemical resistant
design
- Filter change indicator
- Integral pressure regulator and
gauge
- Integrated condensate collection
container
- Up to 4 man capacity
- Water separator pre-filter available
as optional extra
