Why does my ROTORCOMP NK 100 Combistat switch off due to high temperature?
- B
  Bonnie MillerAug 20, 2025
  If the Combistat switches off due to excessively high temperature in your ROTORCOMP Air Compressor, it could be due to several reasons. You should check the oil level in the oil reservoir and top up if necessary. Also, the oil filter might be soiled, requiring replacement of the oil filter cartridge. Other potential causes include a defective thermostat (replace it), a soiled oil cooler (clean it on the air side, and on the oil side if necessary), incorrect installation (observe the installation recommendations), or a defective Combistat (replace it).

  Richard WellsAug 22, 2025
  If your ROTORCOMP Air Compressor experiences oil in the compressed air, you should clean the oil extraction system. Also, check the fine separator cartridge and replace it if necessary. Ensure that the oil level in the oil reservoir is correct, observing the oil level marking; drain and replace oil if there is excessive condensate.

What to do if the safety valve blows off on my ROTORCOMP NK 100?
- L
  Lisa BradleyAug 25, 2025
  If the safety valve of your ROTORCOMP Air Compressor blows off, it could be because the safety valve is defective, requiring replacement. Alternatively, the fine separator cartridge might be soiled, and you should replace the cartridge.

Why won't my ROTORCOMP Air Compressor system discharge or switch off automatically?
- M

  If your ROTORCOMP Air Compressor system is not discharged during continuous operation, or it does not switch off automatically during intermittent operation, causing the safety valve to blow off, it could be due to several reasons. The upper switching point of the network pressure monitor might be set too high, requiring readjustment. Alternatively, the solenoid valve or relief valve could be defective, necessitating replacement. Lastly, the minimum-pressure holding valve might be jammed, requiring you to check it for smooth movement and ensure it moves smoothly.

Why does my ROTORCOMP NK 100 Air Compressor system continually discharge with low feed quantity?
- L
  Lisa HansenAug 28, 2025
  If your ROTORCOMP Air Compressor system continually discharges and has a low feed quantity, the solenoid valve might be defective, requiring replacement. Alternatively, there could be a break in the electric supply line to the solenoid valve, which needs to be eliminated.

Why does my ROTORCOMP NK 100 Air Compressor have no or insufficient feed quantity?
- G
  glenda37Aug 30, 2025
  If your ROTORCOMP Air Compressor has no or insufficient feed quantity, replace the filter insert because the intake filter may be soiled. Check the oil level and top up if necessary, because there might be an oil shortage. Inspect the intake control valve and control valve flap, clean bearings and guides, and check the stroke because the intake control valve may jam or be incorrectly positioned. Check and seal off any leaks in the system.

Why is my ROTORCOMP Air Compressor system difficult to start?
- L
  Lorraine GarciaSep 1, 2025
  If your ROTORCOMP Air Compressor system is difficult to start, check the motor output, drive gear ratio, star-delta switchover, and whether the compressor is flooded with oil or the system has not been discharged yet. Also, check the oil viscosity and belt tension if the ambient temperature is too low, and check the viscosity if the oil filling is too viscous.

What causes the control valve to not open in my ROTORCOMP NK 100 Air Compressor?
- M
  Mr. James HoganSep 3, 2025
  If your ROTORCOMP Air Compressor's control valve does not open, check the system for leaks and seal off if necessary. Also, check the solenoid valve/electrical system, bypass valve, piston gasket, and minimum pressure valve, and replace parts if necessary.

Why doesn't the control valve control (two-point/stepless) in my ROTORCOMP NK 100?
- T
  Taylor BowmanSep 5, 2025
  If your ROTORCOMP Air Compressor control valve does not control (two-point/stepless), check the setting of the pressure switch in the system. Also, if the nozzle for the pneumatic control valve is of incorrect size, replace it with a different nozzle diameter.

Why does oil escape during stop in my ROTORCOMP Air Compressor?
- D
  Deborah CastroSep 7, 2025
  If oil escapes during a stop in your ROTORCOMP Air Compressor, check the sealing surfaces and spring in the control valve for damage and replace parts if necessary.
