What to do if my Porter-Cable CPF6020 is not supplying enough air?

  johnsondavidAug 20, 2025
  If your Porter-Cable Air Compressor isn't providing enough air, it might be due to prolonged excessive use, meaning you should decrease air usage. The compressor might not be large enough for your air needs, so check the accessory's air requirements and consider a larger compressor if needed. A restricted air intake filter can also cause this, so clean or replace it. Check for holes in the hose and replace if necessary. A restricted check valve can also be the cause, so remove and clean, or replace it. Finally, tighten any loose fittings to address potential air leaks.

How to fix air leaks at the check valve of my Porter-Cable Air Compressor?

  Luke BakerAug 22, 2025
  If you notice air leaks at or inside the check valve of your Porter-Cable Air Compressor, it's likely due to a malfunctioning or dirty check valve. A malfunctioning check valve often causes a constant air leak at the pressure release valve when the tank is pressurized and the compressor is off. To fix this, drain the tank, then remove and clean or replace the check valve. Be careful not to overtighten it.

  If your Porter-Cable Air Compressor has air leaks at the fittings, it's likely because the tube fittings aren't tight enough. Tighten the fittings where you hear air escaping. You can also check the fittings with a soapy water solution to find the leaks. Be careful not to overtighten the fittings.

  If there are air leaks between the head and valve plate on your Porter-Cable Air Compressor, it's likely due to a leaking o-ring. Try torquing the head screws to 8 ft. lbs. If the leak persists after tightening, you'll need to replace the o-ring.

Why does the safety valve keep popping off on my Porter-Cable CPF6020 Air Compressor?
- E
  eric19Aug 30, 2025
  If the safety valve on your Porter-Cable Air Compressor is popping off due to excessive tank pressure, it could be that the pressure switch isn't shutting off the motor when the compressor reaches its cut-out pressure, or the pressure switch cut-out is set too high. Try moving the pressure switch lever to the OFF position. If the unit still doesn’t shut off, the electrical contacts may be welded together, requiring you to replace the pressure switch. Contact an authorized service center to check and replace the pressure switch.

What to do if my Porter-Cable CPF6020 leaks air at the pressure switch release valve?

  Aaron BoydSep 2, 2025
  If your Porter-Cable Air Compressor is leaking air at the pressure switch release valve, it could be due to a malfunctioning pressure switch release valve or a malfunctioning check valve. You should remove and replace the release valve. If the check valve is the issue, it will cause a constant air leak at the pressure release valve when the tank is pressurized and the compressor is off. In this case, drain the tank and then remove, clean, or replace the check valve. Be careful not to overtighten.

Why is my Porter-Cable CPF6020 leaking air from the safety valve?
- S
  stephanietorresSep 4, 2025
  If your Porter-Cable Air Compressor has an air leak from the safety valve, there might be a defect in the safety valve itself. Try manually operating the safety valve by pulling on the ring. If the valve continues to leak after that, it should be replaced.

Why does the pressure drop on my Porter-Cable CPF6020 when using an accessory?
- V
  Vincent LeblancSep 9, 2025
  It's normal for some pressure drop to occur on the regulated pressure gauge of your Porter-Cable Air Compressor when an accessory is in use. However, if the pressure drop is excessive, adjust the regulator following the instructions on page 7. Make sure to adjust the regulated pressure under flow conditions, meaning while the accessory is being used.
