I get confused by the hp ratings on these.
With 110 Volts, 1.5 hp from an induction motor is a maximum you get. These high ratings, like a 5 hp compressor on 110 V must used the stored air to get 5 hp, for a short time. that's why your 2hp motor, 220 V industrial unit beats a 5 hp.
I knew a guy who used a smallish compressor, but filled 2- 40 gal hot water tanks with 90 psi before he started into painting a car. (A water tank in our area is rated at 150 psi.) He had lots of air for the job.
