What does the unloader on an air compressor do?
What Is the Purpose of an Unloader Valve? During the operation of a typical reciprocating air compressor, the machine’s electric motor-driven tank fills with air. By venting the air, the unloader valve reduces the load over the piston, facilitating the restarting process.
What is unloader valve in compressor?
It is called the unloading valve. The unloading valve is a small part of the compressor measuring approximately 4-5 inches and width, which performs the critical function of releasing trapped air inside the tank, enabling a motor to restart.
What is unloader in main 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.
What is a unloader valve?
The gun and unloader make up a two-part valve system that directs water into bypass back to the pump or float tank. Generally, unloader valves are pressure-actuated and are opened by the increase in pressure occurring when the valve in the gun closes. Flow-actuated valves are available as well.
How do you know if you have a bad unloader valve?
Water leaks and inconsistent behavior are also signs of a potential failure in the near future. González: The typical signal when there is an unloader malfunction is a reduction of flow through the nozzle, which results in pressure loss. Dean: Typical symptom of an unloader failure is a sudden smooth pressure loss.

Why do you need an air compressor unloader line?
You have a pump on a tank, and added a pressure switch to enable the pump to cycle on demand. An unloader line is typically part of the process to allow the air over the pump cylinder to escape before the pump needs to restart to refill the tank. If the air over the cylinder is not vented, … Read more » Hi Willyr, Yes I get that.
What happens when the unloader valve on a compressor closes?
Unloader valve closes. When the pressure in the compressor tank drops to the cut in pressure setting on your pressure switch, the pressure switch will trip again, and this time the arm or finger will typically release the pin on the unloader valve allowing it to shut, and prevent the air that is being compressed from escaping to atmosphere.
