Hi,

Please post all pressures and temperatures, and I will try to give my oppinion.

The important thing with oil-free compressors is the pressure ratio’s of the low-pressure and high-pressure elements, and the corresponding temperatures.

So please give me:

inlet temp
LP out temp
HP in temp

Intercooler pressure
outlet pressure

Thanks!
