Bullard 41 Series Airline Filters can be used in conjunction with other
compressor safeguards to supply cleaner air to airline respirators. They
can also be used to supply drier, cleaner air to pneumatic tools and
systems. The Bullard 41 Series Airline Filters can be used to remove water,
oil, particulates, odors and organic vapors so that cleaner air is delivered
to workers or equipment. Bullard airline filters will NOT remove
carbon monoxide and other toxic gases from the airline.
Set-Up
1. Location:
Select a flat, stable location to mount the filter. Bolt the filter in
position using the mounting legs. If wall mounting is desired, use the
Model 41P6WM, which is designed with a wall-mount bracket.

Filter must be mounted securely on a suitable base to prevent tipping
over during use. Failure to follow this instruction could result in death
or serious injury.
2. Connection:
Connect compressor hose to the air inlet. Connect the respirator or
pneumatic tool airline hose to the filter outlet. Tighten the connections
to prevent leaks and possible pressure loss.
3. Assembly (41P6 only)
Install the regulator inlet assembly by screwing the 1'' male nipple
on the end of the assembly into the 1'' female inlet port on the filter
body. Use Teflon tape or thread sealant on the male threads before
®
installing. Tighten with a wrench.
4. Handle Kit:
An optional handle kit is available for the 41 Series Airline filters. The
handle is mounted by removing the bolts from the 2 positions shown in
Figure 1. The handle is inserted in the two openings and the threaded
ends of the handle are bolted down from the underside, using the lock
washers and nuts provided.

When using a respirator, do not connect the filter to any air source
unless you are certain it supplies breathable air. Failure to ensure
breathable air source could result in death or serious injury.
Operation
1. Air Requirements
a. Air Source Monitoring:
Federal Law requires use of carbon monoxide and/or high
temperature monitors or alarms when oil lubricated compressors
are used as sources of breathing air. If only a high temperature
alarm is used, you must frequently test the compressor air for
carbon monoxide to ensure it meets the Grade D requirements
discussed below.
The law also requires that breathing air hose couplings be
incompatible with outlets for other gas systems in order to
prevent accidental connection of a supplied air respirator to non-
respirable gases or oxygen.
The 41 Series Airline filters do not remove carbon monoxide and other toxic gases. Review and observe all pertinent federal and state safety regulations
in conjunction with airline respirators. Failure to observe safety regulations or improper use of Bullard Airline Filters could result in death or serious
injury.

b. Quality of Breathing Air:
Supplied breathing air passing through this filter to a respirator
must meet at least the requirements for Type 1 gaseous air
as described in the Compressed Gas Association Commodity
Specification G7.1 (Grade D or higher), as specified by federal
law 42 CFR, Part 84, Subpart J, 84.141(b). The Bullard airline filter
does not remove carbon monoxide and other toxic gases from the
air being supplied. The requirements for Grade D breathable air
include:
• Oxygen
• Hydrocarbons (condensed)
• Carbon Monoxide
• Carbon Dioxide
• No toxic contaminants at levels which would make the air
unsafe to breathe.
Refer to the C.G.A. Commodity Specifications G7.1 for complete
details. It is available from: Compressed Gas Association, 1235
Jefferson Davis Highway, Arlington, VA 22202.
c. Air Pressure:
The air pressure at the filter inlet should not exceed 100 psig (6.89
bar). Air will be released by the pressure relief valve when pressure
within the filter exceeds 125 psig (8.6 bar). Air discharging from the
filter can be controlled to meet specific air pressure requirements
by using the pressure regulator adjustment knob. Refer to
your respirator or pneumatic tool instruction manual to find the
appropriate air pressures required for correct use of the equipment.
d. Temperature:
Air supplied to the filter should not exceed 140° F (60° C).
Therefore, do not connect the filter directly to the compressor
exhaust manifold.
2. Correct Operation Procedures
a. Drain accumulated water and oil from the filter tank as required by
opening the petcock drain valve. Normally the tank will need to be
drained at least once a day. In humid climates, or if large amounts
of water and oil are present in the air supply, drain the filter tank
more often.
b. Tighten the fasteners which secure the head to the filter tank.
Over time, the fasteners may loosen which could cause a leak in
the air system. (Recommended tightness is 20 ft. lbs.)
Refer to Figure 2 on page 2 of these instructions for set-up and
operation.
