Removing air from a compressor typically involves opening the pressure release valve or the drain valve. Here's a more detailed breakdown:
Releasing Air Pressure
This method is used to quickly reduce the pressure within the compressor tank.
- Locate the pressure release valve: This valve is usually located on the tank and is designed for manual pressure relief. It may also be on a pressure switch.
- Open the valve: Carefully pull the ring or lever on the pressure release valve. This will allow the compressed air to escape. Be cautious as the air will escape rapidly and can be noisy.
- Close the valve: Once the pressure is sufficiently reduced (or fully emptied, if desired), release the ring or lever to close the valve.
Draining the Tank (and Releasing Air)
This method also releases air pressure but is primarily used to remove condensation that accumulates at the bottom of the tank. This process inherently releases air.
- Locate the drain valve: The drain valve is almost always at the very bottom of the air compressor tank.
- Prepare for draining: Position a container under the valve to catch the water and any contaminants.
- Open the drain valve: Slowly open the valve. The compressed air will force out any accumulated water. Continue until only air escapes.
- Close the drain valve: Once the tank is fully drained, close the valve tightly.
Important Safety Notes
- Always wear safety glasses when releasing air from a compressor.
- Never attempt to repair a compressor while it is pressurized.
- Regularly draining the tank helps prevent rust and corrosion.
