The outlet air supplied to the respirator is filtered through an activatedcharcoal filter designed to remove tastes and odors from the breathing s FRESH-AIR Pump is oil-less and has rotary carbon vanes.

3 The pump does not produce carbonmonoxide, oil vapors, oil mist or moisture, however it is extremely important that the atmospherefrom which the air is drawn into the pump is clean and free of any carbon monoxide or other toxicgases or vapors. OSHA requires, per 29 CFR , the carbon monoxide in the inlet air to beless than 10 ppm, and that this condition is assured at all times. Sometimes carbon monoxidemonitoring may be required to warn a user, should the CO levels exceed the permissible FRESH-AIR Pump will supply a maximum air flow rate of ten (10) SCFM of breathing air to oneworker or a maximum supply pressure of fifteen (15) psig.

4 The user is responsible for determiningif their respirator will operate properly at these flows and pressures. USE ONLY MSHA/NIOSHAPPROVED RESPIRATORS THAT WILL OPERATE AT PRESSURES LESS THAN FIFTEEN(15) ALL instructions IN THIS MANUAL BEFORE USING THIS FRESH-AIR PUMPMODEL TO OPERATE THIS PUMP IN ACCORDANCE WITH THE INSTRUCTIONSCONTAINED IN THIS MANUAL AND ACCOMPANYING INFORMATION MAY RESULT INDEATH OR SERIOUS INJURY TO THE RESPIRATOR NOT OPERATE THIS PUMP IN AN EXPLOSIVE OR CORROSIVE NOT OPERATE THIS PUMP WHERE IT CAN BE EXPOSED TO ANY LIQUID OR DUSTYMATERIAL.
