Keeping this in view, what is the use of unloader in air compressor?

The air compressor unloader is valve is a small, but important, part of the reciprocating piston compressor. It blows off the pressure inside the discharge pipe when the compressor stops.

how do you fix an unloader valve on an air compressor? Then open the drain valve at the bottom of the tank to depressurize it. Next, remove the 1/4-in. line going to the unloader valve (Photo 1). Then use a slip-joint pliers or small pipe wrench to remove the quick-connect fitting, pressure regulator and gauge from the pressure switch.

Keeping this in consideration, what is an unloader?

The unloader diverts the flow of water from the outlet side of the pump back to the inlet side, causing water to flow in a loop back to the pump under virtually no pressure rather than to the nozzle under operating pressure. Flow may be directed back to the pump inlet or to a float tank or other type of reservoir.

What is unloading of compressor?

Load/unload (sometimes called load / no-load or dual control) requires storage receiver volume, and operates the compressor at full capacity until the unload pressure (cut-out) setpoint is reached. Once a lower load (cut-in) pressure is reached, the compressor returns to full capacity, and the cycle repeats.
