The Central Pneumatic air compressor model 47065 is another model of air compressor sold by Harbor Freight.
It was sold by Harbor Freight around the 2002 area. It had a (reputed) 4 HP motor, a splash lubed air compressor pump on a 21 gallon tank. Since the 47065 was powered by a 120 VAC circuit it might have generated the flow of a compressor with a 1.5-2HP motor, since that size of motor is about all that can be powered by 120 VAC circuit.

I have a central pneumatic 47065 , 21 gal 2.5 hp 125 psi compressor that keeps popping the reset , will always restart just will run more than 30 or 40 secs before tripping .
If bottom tank valve is left open so it won’t build pressure it will run forever, as soon as valve is closed it pops , please help only 10 hours or so on unit , very frustrated !
Thanks
