Why is the capacity of my Corken Air Compressor so low?
- N
  Natalie ParkerAug 17, 2025
  If your Corken Air Compressor has low capacity, several issues could be the cause. The valves might be broken, stuck, or leaking, in which case you should inspect and clean or repair them. A worn piston ring could also be the culprit, so inspect and replace it if necessary. Additionally, a clogged inlet strainer can restrict flow, so clean or replace the screen. Leaks in the piping can also reduce capacity; inspect and repair any leaks. Finally, ensure the 4-way control valve is lubricated by inspecting and lubricating it.

  Jeffrey BrooksAug 20, 2025
  If your Corken Air Compressor is overheating, several factors could be responsible. Start by checking the valves for any signs of damage, sticking, or leaks; inspect, clean, or repair them as needed. A worn piston ring can also cause overheating, so inspect and replace if necessary. A clogged inlet strainer can also lead to this issue, thus clean or replace the screen as necessary. Ensure that the cooling fins are clean, and clean them weekly. For issues such as high inlet or ambient temperature, high compression ratio, or an unbalanced load, it is recommended to consult the factory.

  kristen14Aug 26, 2025
  Excessive noise in your Corken Air Compressor can stem from several sources. Valves that are broken, stuck, or leaking are a common cause; inspect, clean, or repair them. A loose flywheel or belt can also generate noise, so tighten them. If the wrist pin or wrist-pin bushing is worn, replace it. Similarly, a worn connecting-rod bearing should be replaced. An unbalanced load may also lead to noise, in this case inspect the valve or consult the factory.

- A
  angela42Aug 28, 2025
  Excessive vibration in your Corken Air Compressor may be due to several reasons. Broken, stuck, or leaking valves can cause vibration, so inspect, clean, or repair them. A loose flywheel or belt can also lead to vibration, so ensure these are tightened. Worn wrist pins or wrist-pin bushings and worn connecting-rod bearings can also cause vibration and should be replaced. An unbalanced load may also be the cause, in this case inspect the valve or consult the factory. Inadequate compressor base can cause excessive vibration, so you should strengthen, replace, or grout it.

  Monica FosterAug 31, 2025
  Abnormal piston-ring wear in your Corken Air Compressor can be attributed to several factors. Valves that are broken, stuck, or leaking can cause this issue, so inspect, clean, or repair them. A worn piston ring itself can also lead to abnormal wear, so inspect and replace it if necessary. Loose valves, pistons, or packing can contribute to this problem; tighten or replace them as needed. Dirty cooling fins can also cause abnormal wear, so clean them weekly. For issues such as high inlet or ambient temperature, high compression ratio, or an unbalanced load, it is recommended to consult the factory.
