Air Compressor Continuous Run Unloader

An air compressor set up for dual control utilizes a pressure switch and a pilot valve allowing the user to switch between start stop mode and constant speed mode.

Air compressor continuous run unloader.

The 60 to 250 adjustable psi range preset cuts in at 95 psi and out at 115 psi. Compressor for starting or warm up with air pressure in the tank. Continuous run unloader control converts any pressure switch control compressor to a constant speed unloader type. A compressor with this type of unloader typically has a pressure switch that is inserted into the tank under the compressor cover and that style of switch has no place.

Pilot valve check valve and suction or vent unloader valve. Manual knob electric dual control. Since the mark iii is a vent unloader built in compressor head unloaders are not required. Allows you to either run the unit as start stop or constant run.

Browse our variety of tank sizes and styles to find the right constant. Pilot unloader valves are necessary for the proper functioning of most of the continuous run type of compressors those with motors that run all the time. If the cycle time between high and low air pressure set points is too frequent this increases compressor wear and can. In constant speed mode the pilot valve is in control and the compressor will run continuously as described above.

I have a small 1 5 hp continuous run compressor and wanted to turn it into non continuous. The mark iii combines all components required for a continuous run compressor application. Piloted unloader valves combine a pilot valve and an unloader valve to run an air compressor continuously. The pilot valve the vent valve and the check valve.

Be sure to return lever to operating position after starting engine or the pump will not operate at preset pressures. Can be applied to any 30 cfm or less electric or gas engine driven compressor. Some compressors are not able to stop and start frequently enough to supply compressed air to high volume demand plant. A little air bleeds from the hole all the time the compressor is running and for a few seconds after the compressor stops effectively venting air from over the small piston.

While this type of valve is most commonly used on gas powered air compressors it can also be used on electric models. To unload flip lever to in line position. If you re looking for a heavy duty air compressor that can be used 8 10 hours a day a continuous duty air compressor is the right fit for you. When in start stop mode the pressure switch takes over.
