Compressor does not build full pressure

by al
(US)

emglo k15a-8p turns on but does not seem like it is running full speed. it builds pressure slowly and only up to around 80psi. I think it is setup as constant run as when it is full of air, it still runs, but something happens and it runs much quieter. Now the compressor runs in this "quiet" state all the time. any ideas?






Bill answers...

Constant run compressors have valves that control the intake. When the pressure in the tank reaches cut-out pressure, then that valve opens, unloads the compressor, and the electric motor can run with almost no load, saving wear, tear and energy cost.

If your compressor only runs "unloaded", then you've got a problem with the unloader circuit I would say.

Can you refer to your manual, or contact the manufacturer? If not, it's off to your local Repair shop. See the Repairs page listed on the Nav bar to find a local repair shop for you.

Cheers,

Bill
