This manual contains important information that all users must know and understand
before using the equipment. This information relates to USER SAFETY and PREVENT-
ING EQUIPMENT PROBLEMS.
To help you recognize this information, we use the following terms to draw your at-
tention to certain equipment labels and portions of this manual. Please pay special
attention to any label or information that is highlighted by one of these terms:
Important information
to alert you to a situation
that might cause serious
injury if instructions are
not followed.
BREAThING AIR REQUIREMENTS
Supplied breathing air, as defined by
OSHA 29 CFR 1910.134i and NIOSH 42 CFR
84.141, MUST meet or exceed the following
requirements for Type 1-Grade D breath-
able air, as defined in Compressed Gas
Association (CGA-G7-1-1997):
Oxygen = 19.5-23.5% (Typical
atmospheric levels)
Oil (condensed) = 5 mg/m (mil-
ligrams per cubic meter) maximum
Carbon Monoxide (CO) = 10 ppm
(parts per million) max.
Carbon Dioxide (CO
(parts per million) max. (Typical
atmospheric levels)
Odor = The presence of a pro-
nounced odor should render the
air as unsatisfactory
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, when added to a DAD-500,
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.

SERVICE BULLETIN
SB-6-176-C
Replaces SB-6-176-B
This filter unit, when added to a DAD-
500, 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 Breath-
able Air and Compressed Breathing Air,
CSA-Z180.1 when:
• The filter unit is connected to a
compressed air source:
 The compressor is properly
maintained
 The air compressor intake is
located in a clean contaminate
free location
 The air compressor is draw-
ing in typical atmospheric air,
meeting all of the national
and local requirements for
breathing air
• The filters are properly maintained
• A properly operating CO monitor
is installed
Risk of explosion or fire.
Improper use can cause
personal injury.
• This product is designed and
intended for use in industrial com-
pressed air systems only. Do not use
for liquids or gasses other than air.
• Do not use where pressure or tem-
perature can exceed rated operating
conditions (see specifications).
• Regulated outlet pressure must
never be set higher than the maxi-
mum operating pressure of the
downstream air tool or equipment.
An outlet pressure gauge should
always be used.
Risk of illness or death. Carbon
monoxide can cause nausea, faint-
ing or death. Stop using if carbon
monoxide is present. This unit does
not remove carbon monoxide. A
carbon monoxide monitor should be
incorporated into your air supply line
to warn of the presence of carbon
monoxide.
