Oil mist from the compressor lubricating oil must not be present when the air reaches the air
control device. Excessive amounts of water vapor and any particulate matter should also be
removed as they may affect performance of the air control devices.
Where large amounts of aerosols of oil, water and other liquids are present, an optional coalescing
prefilter should be installed on the input side of the 3M filter and regulator panel.
NOTE: Carbon monoxide
Although it is theoretically possible that oil lubricated compressors can create carbon monoxide
(CO) if the compressor overheats, studies have shown that the location of the compressor’s air
intake is the most likely source of carbon monoxide contamination.

According to OSHA
regulation [29 CFR (1910.134)(i)], periodic CO monitoring, rather than continuous CO monitoring
with an alarm, is acceptable if the oil lubricated compressor is equipped with a high temperature
alarm and automatic shut-down. In Canada, follow CSA Z180.1 regarding oil
lubricated compressors.

To meet NIOSH requirement 42 CFR 84, subpart 84.150 for minimum and maximum airflow
(4-15 cfm, 113-425 lpm), the air control valves approved for use with the 3M respirators must
be operated within the supply pressure ranges and hose lengths stated in their
User Instructions.
Failure to do so may adversely affect respirator performance and result in sickness
or death.
You must comply with OSHA standard 29 CFR 1910.134, which states that, “Airline couplings
shall be incompatible with outlets for other gas systems to prevent inadvertent servicing of
airline respirators with nonrespirable gases or oxygen.” In Canada, refer to the requirements of
CSA standard Z180.1.
Failure to do so may result in sickness or death.
Your employer must provide breathing air that meets at least the requirements of the
specification for Grade D breathing air, as described in the Compressed Gas Association
Commodity Specification G-7.1-1997 in the United States. In Canada, refer to CSA standard
Z180.1, table for the quality of compressed breathing air.
Failure to do so may result in
sickness or death.
There is no assurance that by using the 3M™ Portable Compressed Air Filter and Regulator
Panel 256-02-01, with Carbon Monoxide (CO) Monitor the filtered compressed air will meet
the requirements of Grade D breathing air. In Canada, refer to the requirements of
CSA standard Z180.1.
The line pressure must be kept within safe limits, 125 psig (8.75 kg/cm
2
) maximum. Dirt, oil
and water, unless trapped or filtered out, may continue downstream in concentrated form and
adversely affect the performance of the respirator and
may result in sickness or death.
