Wondering why your air compressor might not be building pressure? There are numerous potential causes for an air compressor not building pressure. The most common issues include:
- A blockage in the air intake
- A problem with the unloading valve
- Worn out piston rings
- A damaged or broken gasket
Air Intake Issues
One of the most common reasons why an air compressor might not be building pressure is due to a blockage in the air intake. If there is something blocking the air intake, it will restrict the airflow and prevent the compressor from building up enough pressure.
If this is the issue, a new inlet valve could be the thing you need to restore pressure.
Broken Unloading Valve
Another potential cause for an air compressor not building pressure is a problem with the unloading valve. The unloading valve is responsible for releasing the pressure when the compressor is turned off. If the unloading valve is damaged or broken, it can cause the compressor to not build up enough pressure.
Order a new unloading valve in our online store to get a jump on this issue.
Worn Out Piston Rings
Worn out piston rings can also prevent an air compressor from building up enough pressure. Piston rings are responsible for sealing the air inside the chamber and if they are worn out, it can allow air to escape, which will prevent the compressor from reaching its full potential.
We have piston rings that can help you restore your compressor to working condition.
Damaged or Broken Gasket
Finally, a damaged or broken gasket can also be responsible for an air compressor not building up enough pressure. The gasket seals the air chamber and if it is damaged, it can allow air to escape, which will again prevent the compressor from reaching its full potential.
Order from over 500 gaskets to help you resolve your bad seal.
