!Air compressors are very inefficient machines. Almost 90% of the electric power input is converted into heat. Most of this heat is removed from the compressor by the ventilation air coming out through the cooler on the compressor.
It is imperative to take hot air coming out from the cooler is not sucked back by the compressor and removed from the environment. Consult appropriate HVAC specialist for the proper ventilation.

10hp compressor generates approximately 25,000 BTU/h heat at full load. This heat must be removed from the environment compressor is working.

Air cooled compressor there is/are fan(s) blowing air throughout from the cooler and from the top of the compressor. Compressor Ventilation fan(s) kicks in when compressor element (airend) outlet temperature reaches to 185F(85C) and stops at167F(75C). Models equipped with fan inverter, once fan kicks in at 85C, it may never stop but fan speed is regulated to have the optimum cooling for the most efficient compressor element (airend) temperature..

Make sure Fan is sucking from the side(s) of the compressor and pumps it from the top, through the Air/Oil cooler. If fan is sucking from the top and pumps the hot air through the side(s) of the compressor, immediately change the main power input phase sequence to ensure correct direction of fan (Such change will not affect the main motor direction of rotation). Failure to do so will cause inverter to overheat and destroyed very quickly. In such case A-17 warning followed by E-17 error is going to be observed.

Make sure the hot ventilation air is not sucked back (Bypassed) to the ventilation air inlet side(s) of compressor. Hot ventilation air must be dissipated from the environment where compressor is operating. In order to do so, and appropriate ventilation duct may be needed. In such case, DO NOT reduce the cross section area smaller than compressor cooler face area and do not create back pressure, head pressure more than 10KPA by the ventilation duct.
