The motor mfg doesn't want to be complicit on the out right lying done by the compressor mfgs, who never heard that 750 watts = 1 hp. NOTHING beats Shop-Vac HP ratings. 6HP from a 15 amp 120v outlet! Awesome! G Good golly, I hadn't noticed that before! 15 amps at 120 V is 1800 watts Roughly 746 (100% efficiency) watts per HP 750 x 6 = 4476 watts Less than 1/2 the claimed power! I wonder if I could take it back and exchange it for a REAL 6 hp vac???
