How to fix low discharge pressure on my ETQ A16?

  heidi02Aug 14, 2025
  Low discharge pressure in your ETQ Air Compressor can occur if the air demand exceeds the pump capacity, so decrease the air demand or use a larger capacity air compressor. It can also result from leaking air; listen for escaping air and apply soap solution to all fittings and connections, tighten or replace leaking parts. A restricted air intake can also cause this, so clean the air filter element. Other potential causes include blown gaskets (replace faulty gaskets) or leaking/damaged valves (inspect and replace defective parts).

  Excessive oil in the air supply from your ETQ Air Compressor can be due to several reasons. It might be caused by worn piston rings, which require replacement with new rings. Another cause could be a clogged air intake, so you should clean the air filter. Also, check if the oil level in the compressor head is too high and drain some of the oil if needed. Finally, ensure you are using the correct oil viscosity, which should be SAE30.

  Excessive or abnormal noise from your ETQ Air Compressor might be due to several factors: * Loose motor: Tighten the motor bolts. * Low oil in crankcase: Refill oil to the proper level and check for damage to bearings or oil leaks. * Worn connecting rods: Replace the connecting rod and maintain oil level and change oil more frequently. * Worn piston pin: Remove the old piston pin, measure and verify specifications are within limits. If not, replace piston pin and replace oil more frequently. * Piston hitting valve plate: Remove the compressor head and valve plate for carbon deposits or other foreign objects. Replace the head and valve plate and use a new gasket. * Noisy check valve: Replace the check valve.

What to do if my ETQ A16 Air Compressor tank doesn't hold pressure?
- K
  Kathleen GonzalesAug 25, 2025
  If your ETQ Air Compressor tank isn't holding pressure when off, it could be due to a worn check valve, which should be replaced. Also, check all connections and fittings for leaks and tighten them. Inspect the tank for cracks or pin holes; if found, replace the tank, and never attempt to repair a damaged tank.

Why is the pump on my ETQ A16 overheating and damaging the air filter?
- B
  Billy BeardAug 28, 2025
  The pump overheating and damaging the air filter on your ETQ Air Compressor could be due to a missing insulating gasket between the filter and head; install the gasket. It could also be caused by broken valves or a blown gasket, in which case, replace the valves or install a new gasket.

What causes the pressure switch on my ETQ Air Compressor to continuously blow air out the unloader valve?
- L
  Lisa HarrisSep 5, 2025
  If the pressure switch on your ETQ Air Compressor continuously blows air out the unloader valve, it is likely due to a malfunctioning check valve. Replace the check valve if the unloader valve bleeds off constantly.
