Do Not Use For
Filtering and regulation of air sources when airborne contaminant concentrations are unknown or
immediately dangerous to life or health (IDLH), unless used in conjunction with a back-up escape
system or a self-contained breathing apparatus/supplied air respirator (SCBA/SAR),
where applicable.
General Description
A complete 3M filter and regulator panel will operate as follows. (Fig. 1)
1. Air entering the four-stage filtration system at the inlet (A) is usually contaminated with oil,
water, dirt, rust, scale and vaporous hydrocarbons.
2. As the air passes through the first stage of the prefilter (B), particulate matter 3.0 microns and
larger are trapped and retained.
3. The air then enters the second stage of the prefilter (C) which traps particulate matter larger
than 0.3 microns and coalesces liquid aerosols with an efficiency rating of 99.97%. The liquid
contaminates are trapped in the lower chamber of the prefilter and expelled through the
automatic float drain (D).
4. The third stage (E) and fourth stage (F) contain a bed of odor absorbing activated charcoal.
5. The air is then passed through the air pressure regulator (G), which is used to adjust the air
pressure going to the respirators.
6. A sample of the filtered air is taken at (H) and passed through the carbon monoxide monitor (I).
7. The carbon monoxide monitor continuously checks the carbon monoxide concentration and
digitally displays the amount present in ppm (parts per million). An audio and visual alarm will
alert operators if carbon monoxide concentrations exceed a preset level (10 ppm USA;
5 ppm Canada).
CAUTION
This panel will not remove carbon monoxide.
