SYMPTOM: Outlet Air Pressure Too Low
1. Be sure you know the proper pressure range for the respirator - see the
respirator’s instruction manual.
2. Be sure the respirator and air supply hose are connected when the gauge
reading is taken.
3. Check to see that the gauge is functioning properly. Replace the gauge if broken
or malfunctioning.
4. Check to see that the outlet filter jar is seated firmly into the filter housing’s
O-ring so that no air can escape. Replace the jar and/or O-ring if damaged
or worn.
5. Check to see that no air is escaping from the relief valve in the outlet filter
body. Reset the pressure adjustment valve if necessary.
6. Check that both the inlet filter (Cat. No. 23611) and outlet filter (Cat. No.
S17101) are clean and replace if necessary. Dirty filters restrict air flow.
7. Flush the pump with Loctite Safety Solvent (Cat. no. S17931) to remove
excessive dirt, sand, particles, moisture or oil in the rotor assembly.
See the Maintenance Section on Page 7 of this manual for proper directions
on flushing the pump.
When the parts are reassembled, attach the respirator and turn the pump
on, monitoring the outlet pressure.
8. Check to make sure that the carbon vanes do not need to be replaced. Worn
vanes may not produce as much flow.
9. Make sure there is nothing obstructing the airline supply hose.
SYMPTOM: Outlet Pressure Too High
1. The pressure adjustment valve is set too high - reset to a lower pressure. Be
sure the outlet pressure remains in the proper range for the respirator as
specified by the respirator manufacturer - see the respirator’s instruction
manual.
2. Check the respirator’s air supply hose for kinks.
SYMPTOM: Pump Overheating
1. 160° - 200°F (71° - 93°C) is normal output air temperature when the pump
is conintuously running. This heat is dissipated as it travels through the
respirator’s air supply hose until it reaches ambient air temperature.
2. Make sure that both the inlet and outlet filters are clean. Replace if
necessary.
3. The pressure adjustment valve is set too high - reset to a lower pressure.
Be sure the outlet pressure remains in the proper range for the respirator
as specified by the respirator manufacturer - see the respirator’s
instruction manual.
4. Flush the pump with Loctite Safety Solvent (cat. no. S17931) to remove
excess dirt, sand, particles, moisture or oil in the rotor assembly.
See the Maintenance Section on page 7 in your user manual for proper
directions on flushing the pump.
When the parts are reassembled, attach the respirator and turn the pump
on, monitoring its performance for overheating.
5. The electrical circuit to which the pump is connected is overloaded.
Check the amperage load of the circuit and disconnect other electrical
equipment, if necessary, from that circuit.
TIP:
If ambient air temperatures are high, place the Bullard Free-Air
®
Pump in the shade. Do not lay air line hoses directly on blacktop. Also, be
sure all fittings are at least 1/2” ID.
SYMPTOM: Outlet Air Temperature Too Warm
1. Be sure that at least the first 50 feet (15 m) of air supply hose closest to
the pump is laid out (not coiled) to permit excess heat to dissipate from the
hose.
2. Keep the air supply hose out of direct sunlight and off warm or hot
surfaces.
3. Put a coiled section of the air supply hose in the bottom of a large
container. Fill the container with water and ice and cover with a lid. For
best results, locate the container as close to the worker as possible.
SYMPTOM: Outlet Air Temperature Too Cold
1. Let the pump warm up approximately 15 minutes before using.
2. Coil the first 25-50 feet (7.6-15 m) of air supply hose closest to the pump.
3. Keep the air supply hose off cold surfaces.
SYMPTOM: Moisture in Air Supply Hose Line
1. Locate the air inlet filter in a dry, clean air location, where breathable air
can be assured at all times.
2. With the air supply hose connected to the pump, but not the respirator,
turn the pump on and let it run for approximately 15 minutes to purge the
hose of excessive moisture.
3. Between uses, hang the hoses so extra moisture may drain.
