What to do if Bauer Compressors Junior II WT does not attain final pressure?
- K
  Krista AustinAug 16, 2025
  If your Bauer Compressors Air Compressor is not reaching the desired final pressure, there are several potential causes. First, check the condensate drain valve(s) for leaks and tighten or reseal them. If the final pressure safety valve is blowing too soon, it may be defective and need replacement. Also, ensure that the vent screw for the final pressure safety valve is in the operating position; unscrew it until completely open for venting. Finally, if you're using a P21 Filter system, check for a missing cartridge, which could cause air to escape. If missing, replace the cartridge.

  If the air delivery of your Bauer Compressors Air Compressor is dropping, start by checking the intake filter. If it's soiled, clean or replace the filter cartridge. Then, inspect the pipe couplings and retighten any that are leaking. Finally, excessive wear of the 3rd stage piston can also cause this issue; if necessary, replace the piston and sleeve of the 3rd stage.

  Robin LawrenceAug 22, 2025
  If your Bauer Compressors Air Compressor is overheating, several factors could be the cause. Insufficient cooling air, high ambient temperature (above 113°F or 45°C), incorrect direction of rotation, or leaking inlet and pressure valves in one stage can all contribute to overheating. Ensure adequate ventilation, check the ambient temperature, correct the rotation if needed, and inspect the valves, cleaning or replacing them as necessary.
