Central Pneumatic Model 47065

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.

Lots of folks bought this model. This is the forum page for owners and users of the Central Pneumatic 47065 air compressor.
