If the oil temperature drops below 40°C or exceeds 90°C, the oil’s quality can deteriorate, leading to potential damage and reduced compressor life. When the oil temperature is too low (below 40°C), the oil becomes too viscous, causing increased friction within the compressor.
[pdf] An oil analysis ensures that the oil maintains the right viscosity, additives, and cleanliness levels required for efficient operation. Monitoring the oil’s condition helps prevent excessive wear and tear on critical components such as bearings and rotors.
[pdf] Try to turn the compressor by hand. It should be possible to turn it around. It should turn around smoothly, without any 'hickups' (be sure to completely shut down the air compressor!). Check the isolation of the motor windings.
