READ ALL INSTRUCTIONS IN THIS MANUAL BEFORE USING FREE-
AIR PUMP MODEL ADP20.
FAILURE TO OPERATE THIS PUMP IN ACCORDANCE WITH THE
INSTRUCTIONS CONTAINED IN THIS MANUAL MAY RESULT IN DEATH
OR SERIOUS INJURY TO THE RESPIRATOR WEARER.
1. Locate the pump’s Inlet Air Filter in a place where there is clean,
breathable air at all times. The pump WILL NOT remove toxic gases
or other contaminants from the incoming air it transfers to the respi-
rator wearer.
See the BREATHING AIR REQUIREMENTS section on page 5 for spe-
cific details on breathing air quality.
2. This pump will supply at least the required minimum volume of air (6
cfm for hoods or 4 cfm for tight fitting masks) to low pressure, sup-
plied-air respirators. The respirators must be approved by
MSHA/NIOSH to operate at less than 25 psig.
Be sure that the pump’s outlet pressure, measured by the pressure
gauge on the pump, is maintained above the minimum pressure set-
ting required by the respirator manufacturer.
To be assured your respirator can be used with this pump refer to
the section in the respirator’s Instruction Manual for the respirator’s
approved pressure range and permissible air supply hose length.
If you have any questions about whether or not your respirator is
compatible with this pump, contact Bullard’s Inside Sales
Department at 800-827-0423 or 606-234-6611.
3. Supplied-air respirators used with this pump must not be worn in
any atmosphere immediately dangerous to life or health or from
which the wearer cannot escape without the use of the respirator.
4. When connecting your respirator to the Free-Air Pump use only the
air supply hose and couplings required by the respirator manufacturer
and approved by MSHA/NIOSH.
Use of non-approved hose or couplings will void the respirator’s
MSHA/NIOSH Approval and could reduce the air flow to the respirator,
resulting in possible death or serious injury to the respirator wearer.
