Temperature alarms, errors, limits

40F (5C)

Should compressor to run at lower ambient temperatures, consult Us Air Compressor. Below 40F(5C) compressor will run for few seconds and stop with an error code.

105F (40C)

165F (75C)

Running at lower temperature will cause condensation and destroy the compressor. For pressures above 150PSI minimum temperature compressor must run is 185F.

If compressor internal temperature is below 165F (75C) compressor will keep running even though there is no air demand. if the air demand is low or none, the discharge valve may constantly dump air to ensure onload operation to warm compressor above 165F (75C) quickly. Dumping action may cause cycling discharge action and cause cycling air discharge noise. This is completely a normal reaction of the compressor during heating cycle. This process called heating function.

185F (85C)

• life of oil to get shorter rapidly,
• oil carry over to the system
• oil spill in the compressor including air filter housing,
• reduce the life of airend bearings,
• reduce the performance of the compressor.
  

212F (100C)

If compressor element temperature rises protection limit, compressor will reduce the max. allowed speed to a lower value, pump almost half of the air so that it can keep working with less cooling demand. Whenever temperature drops below 90C compressor will start runinng at the full speed and deliver the max air flow it is designed to. click here for more information
