I have purchased an air compressor that originally came equipped with 10 hp motor. Now has 7.5 motor 3470 rpm with same drive pulley. I knew this would not work so I reduced drive to 4.5". Was 7" drive 18" driven. It still pulls 60 amps at the end of cycle (150 psi.) Questions: Could I further reduce drive pulley size and use this motor or best to replace motor with 7.5 high torque 1750 rpm motor and which drive pulley to use with these combos.? |

By my calculations your pulley change should have worked. You may consider installing a larger driven pulley. Can you stand the loser CFM's and time to recover? If not, you may have to again install a 10 HP motor. Was the 10 HP motor burned up?? Most compressors are intended ot bring up 120 PSI or there abouts. You may even have to go to a 21 inch driven or a 12 HP motor.. do you see my point? The worst suggestion of your lifetime may be the catalyst to the grandest idea of the century, never let suggestions go unsaid nor fail to listen to them. |
