Air Compressor Continuous Run Unloader

To unload flip lever to in line position.

Air compressor continuous run unloader.

I have a small 1 5 hp continuous run compressor and wanted to turn it into non continuous. 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. 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. Browse our variety of tank sizes and styles to find the right constant.

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. Some compressors are not able to stop and start frequently enough to supply compressed air to high volume demand plant. 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. Since the mark iii is a vent unloader built in compressor head unloaders are not required.

Piloted unloader valves combine a pilot valve and an unloader valve to run an air compressor continuously. When in start stop mode the pressure switch takes over. Be sure to return lever to operating position after starting engine or the pump will not operate at preset pressures. When the the air compressor unloader valve is working correctly the pressure in the tank has dropped to below the normal cut in pressure level of the pressure switch the pressure switch trips to allow power to flow through it and the motor starts.

While the air compressor is running the pilot remains closed until the pressure reaches the unload setting. The pilot valve the vent valve and the check valve. Manual knob electric dual control. 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. Can be applied to any 30 cfm or less electric or gas engine driven compressor. Built to withstand constant use in a contractor or commercial setting these compressors will work as long and as hard as you do. In constant speed mode the pilot valve is in control and the compressor will run continuously as described above.

While this type of valve is most commonly used on gas powered air compressors it can also be used on electric models. Allows you to either run the unit as start stop or constant run. 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. Compressor for starting or warm up with air pressure in the tank.
