Rotary Vane System

Ambient Air Pump 86610

Honeywell ambient air pumps use an oil-less rotary vane system to supply ambient air to a continuous flow respirator.

Inlet and Outlet Filter Assemblies

There are two filter assemblies, one inlet and one exhaust. These filters protect the pump mechanism and do not filter contaminated air or provide oxygen.

Pressure Gauge

The pressure gauge provides the dynamic pressure, or back pressure, and is measured in Pounds per Square Inch Gauged (PSIG), and are not an indication of the flow of air. Refer to the Operating and Maintenance Instruction Manual of your respirator for the correct pressure setting for your supplied air system.

Pressure Relief Valve

Your ambient air pump includes a pressure relief valve that will be used to set the correct pressure for your respirator.

Electric Cord

The On/Off switch is integrated into the electric cord of 86610 3/4 HP pump and on the unit of 86630 1.5 HP pump. Your ambient air pump uses a standard outlet of 115V/230V.

Male Thread Connections

The 3/4 HP pump includes two and the 1.5 HP includes three male threaded connections to be used to connect the breathing hose of your respirator(s). The threaded connections are 3/8” NPT. Bushings may be required if the female connection of your hose or couplers is another size.

Note

Honeywell offers several brands of quick connect couplers so you can select one that is incompatible with any couplers used at your site for non-breathing air and other gases. A coupler assembly includes one male and one female to be used at the connection of hose to the muffler assembly. Sperian brand hoses include OBAC couplers pre-assembled to the breath- ing air hose, and pumps come with compatible couplers to be used with Sperian hoses only.
