Max. Pressure: 150 PSIG
Max. Temperature: 150°F
Regulated Pressure Range: 2-125 psig
BREATHING AIR REQUIREMENTS
Supplied breathing air, as defined by
OSHA 29 CFR 1910.134(i), NIOSH 42 CFR
84.141, and CSA CAN 3-Z180.1-00 MUST
meet or exceed the following requirements
for Type 1-Grade D breathable air, as
defined in Compressed Gas Association
(CGA-G7-1-1997):
Risk of illness or death. Carbon monoxide
can cause nausea, fainting or death. Stop
using if carbon monoxide is present. This
unit does not remove carbon monoxide. A
carbon monoxide monitor should be incor-
porated into your air supply line to warn of
the presence of carbon monoxide.
It is up to the employer to assure that the
air compressor is properly maintained, that
the air compressor intake is located in a
clean contaminate free location and that
the air compressor is drawing in typical
atmospheric air, meeting all of the national
and local requirements for breathing air.

This filter unit does not remove or filter
Carbon Monoxide (CO). It is up to the
employer to ensure that the level of CO
does not exceed the maximum national or
local allowed level. The recommended
method to assure that the CO level is not
exceeded is to install a carbon monoxide
monitor and alarm.
This filter unit will only remove particulate
matter, water, oil and odor. This filter unit
will meet the particulate matter, oil and
odor requirements of Type 1-Grade D
