Manual No. 04143
WARNING
Respirator(s) must be supplied with at least
Grade "D" quality respirable air, containing no
less than 19.5 volume-percent of oxygen.
Breathing air requirements are described in
Compressed Gas Association, G-7.1.,
Commodity Specification For Air, published by
Compressed Gas Association Inc., Chantilly,
VA. CGA Website is cganet.com. If air quality is
unknown, consult a safety professional and/or
industrial hygienist. Poor quality air will cause
serious respiratory injury or death to the user.
1.4 General
Description
1.4.1
The CPF is a particulate filter, which removes
mists (including oil mist), water vapor and particulate
matter, down to 0.5 micron in size from breathing air
supplied by a breathing-air compressor.
The CPF Filter
does not detect or remove carbon monoxide (CO) or
any other toxic gases.
Filter effectiveness and cartridge
life will be reduced considerably if the supplied air is
heavily contaminated with particulate matter or moisture.
1.4.2
The main components of the filters are shown in
Figure 1. The CPF-20 is equipped with an outlet that
supplies filtered air to one or two supplied-air respirators.
The CPF-80 has four outlets, and will accommodate up
to four supplied-air respirators with total air requirement
not to exceed 100 cfm.
WARNING
Respirators are NIOSH-approved to operate
within specific pressure ranges. When
connecting multiple respirators, make sure that
all respirators are approved to operate within
the same pressure range. Operating the
respirator outside of the approved pressure
range will increase or restrict airflow beyond
permissible limits.
1.4.3
Compressed air enters the filter through either of
the two side inlet ports. Moisture condensing inside the
filter is drained through the petcock at the bottom of the
filter body. Air is forced through a replaceable filter
cartridge, which contains several filtering materials,
which traps particulates.
1.4.4
Outlet pressure is adjusted by the knob on the
pressure regulator. Both filters are equipped with a
pressure relief valve. The relief valve is an audible signal
that pressure is exceedingly high.
