If your oilless oil free air compressor won't build pressure, there could be a number of potential causes. In this article, we will discuss some of the most common issues and how to troubleshoot them.
Check for Leaks: One of the most common reasons for an oilless oil free air compressor failing to build pressure is leaks in the system. Check all connections and hoses for leaks, and tighten or replace as necessary. Also, check the tank for cracks or damage that could be causing air to escape.
Inspect the Check Valve: The check valve is responsible for ensuring air only flows in one direction, from the compressor to the tank. If the check valve is damaged or malfunctioning, it could be causing air to escape from the tank and prevent pressure from building. Inspect the check valve and replace if necessary.
Check the Pressure Switch: The pressure switch is responsible for turning the compressor on and off based on the desired pressure level. If the pressure switch is malfunctioning, it could be preventing the compressor from building pressure. Check the switch for damage or loose connections, and replace if necessary.
Inspect the Piston and Cylinder: The piston and cylinder are responsible for compressing air and storing it in the tank. If there is damage or wear to either of these components, it could be preventing the compressor from building pressure. Inspect the piston and cylinder for damage or wear, and replace as necessary.
Check the Air Filter: A clogged or dirty air filter can reduce the efficiency of the compressor and prevent it from building pressure. Check the air filter and clean or replace as necessary.
In conclusion, a failure to build pressure in an oilless oil free air compressor can be caused by a number of factors, ranging from leaks in the system to malfunctions in key components like the check valve or pressure switch. By following these troubleshooting steps, you can identify and address the root cause of the problem and get your compressor back up and running in no time.
