Air Compressor Continuous Run Unloader

Be sure to return lever to operating position after starting engine or the pump will not operate at preset pressures.

Air compressor continuous run unloader.

The pilot valve the vent valve and the check valve. Compressor for starting or warm up with air pressure in the tank. Built to withstand constant use in a contractor or commercial setting these compressors will work as long and as hard as you do. 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.

Manual knob electric dual control. 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. Can be applied to any 30 cfm or less electric or gas engine driven compressor.

To unload flip lever to in line position. When in start stop mode the pressure switch takes over. Some compressors are not able to stop and start frequently enough to supply compressed air to high volume demand plant. Piloted unloader valves combine a pilot valve and an unloader valve to run an air compressor continuously.

I have a small 1 5 hp continuous run compressor and wanted to turn it into non continuous. Pilot valve check valve and suction or vent unloader valve. 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. 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 the cycle time between high and low air pressure set points is too frequent this increases compressor wear and can. 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. The mark iii combines all components required for a continuous run compressor application. Browse our variety of tank sizes and styles to find the right constant.

Since the mark iii is a vent unloader built in compressor head unloaders are not required. 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. 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. The 60 to 250 adjustable psi range preset cuts in at 95 psi and out at 115 psi.
