Air Compressor Continuous Run Unloader

When in start stop mode the pressure switch takes over.

Air compressor continuous run unloader.

The 60 to 250 adjustable psi range preset cuts in at 95 psi and out at 115 psi. The mark iii combines all components required for a continuous run compressor application. 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. To unload flip lever to in line position.

Some compressors are not able to stop and start frequently enough to supply compressed air to high volume demand plant. Compressor for starting or warm up with air pressure in the tank. Since the mark iii is a vent unloader built in compressor head unloaders are not required. I have a small 1 5 hp continuous run compressor and wanted to turn it into non continuous.

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.

Continuous run unloader control converts any pressure switch control compressor to a constant speed unloader type. 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. Manual knob electric dual control. Piloted unloader valves combine a pilot valve and an unloader valve to run an air compressor continuously.
