Cartridge Replacement
�
WARNING
Use only Bullard 41AF cartridges as replacements. Bullard AirGladiator Filters
are designed to use only Bullard filter cartridges. Failure to use the correct filter
cartridge could result in death or serious injury.
The frequency of filter cartridge replacement depends on the conditions of the particular
air system in which the filter is installed. However, the filter cartridge should be replaced
immediately if:
a. The user smells or tastes contaminants in the air being supplied to an air-supplied
respirator, or;
b. There is a large pressure drop in the system, even though the compressor and other
components appear to be operating correctly.
C. The filter has been in use for approximately one (1) year.
Corrective Action
1. Shut off air supply and drain filter. Disconnect the filter from the air source before servicing.
2. Replace the Cartridge:
a. Separate the filter head from the cylinder housing by removing the bolts and lock
washers from the top flanges.
b. After removing the 41AF filter cartridge, clean the inside of the tank to remove any
remaining contaminants.
c. Insert a new Bullard 41AF filter cartridge. Tighten the fasteners across from each
other and not in a circular sequence. This will help prevent warping of the filter head
(Recommended tightness = 20 lbf·ft).
3. Record the date the filter was replaced on the label attached to the airline filter tank. You
can develop a filter cartridge replacement schedule by monitoring the frequency with
which the cartridge needs to be changed.
4. Reconnect the filter to the air source before use.
5. If conditions are not improved, do not use the filter until appropriate corrective measures
have been taken.
Replaceable Filter Cartridge 7-Stage Operation
Cartridges effectively trap and remove impurities with little pressure loss. The supplied-air
enters the filter at inlet connector travels through 6 layers of filter material and exits at outlet
connector. Filter materials work in sequence to trap and hold water, oil, odors, and organic
vapors so that cleaner air is delivered to workers or equipment.

WARNING
Filter cartridge must be changed periodically for maximum efficiency. Frequency of
cartridge changes depends on operating conditions. Cartridge should be changed
immediately if respirator wearer feels, smells or tastes contaminants inside the
respirator. Filter tank should be drained at least daily to remove trapped water and
oil (a petcock is provided on the bottom of the tank for this purpose). Failure to follow
these instructions could result in death or serious injury.
