MSHA/NIOSH APPROVED RESPIRATORS THAT WILL OPERATE AT PRESSURES LESS THAN FIFTEEN (15) PSIG.
Be sure that the pump’s outlet pressure, measured by the pressure gauge on the pump, is maintained above the minimum pressure
setting required by the Respirator manufacturer. REFER TO YOUR RESPIRATOR MANUAL FOR CORRECT PRESSURE
REQUIREMENTS, PERMISSIBLE HOSE LENGTHS AND FITTING TYPES. FAILURE TO COMPLY WITH THE
RESPIRATOR MANUFACTURER’S REQUIREMENTS WILL VOID THE MSHA/NIOSH APPROVAL(S) AND COULD
RESULT IN DEATH OR SEVERE INJURY.
Questions regarding whether or not your Respirator is compatible with this pump can be directed to 3M Canada’s Occupational
Health and Environmental Safety Hotline at 1-800-267-4414.
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.
When connecting your respirator to this device, use only the air supply hose and couplers required by the respirator manufacturer and
approved by MSHA/NIOSH.
Use of non-approved hose or couplers 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.
If your hose and couplers are not compatible with the coupler supplied on this pump, you may change the coupler on this pump to
provide the proper connection. Contact the factory with any questions regarding the type of fittings that can be used with this pump.
DO NOT modify or alter this pump in any manner. Use only approved MST replacement parts and components. Failure to use
approved MST components and replacement parts invalidates all MST warranties, and may result in death or serious injury to the
respirator wearer.
