Air compressor / electrical Q's
Doing research on air compressor for the shop. I have 240-V single phase power,
I can go as high 50 amps on the breaker, possibly even a little more.
Without looking closely at my demands for air pressure and volume, I always assumed
more is better. With the above electrical, I figured I could power a 10-hp motor.
I find now that 7.5-hp seems to be the common cutoff for single phase power
compressor availability. Maybe that's enough. I think the largest air demand I'd need
would be for sandblasting. What are your opinions about 7.5-hp being enough
compressor for a home setup doing bodywork ?
One brand name I saw was JENNY, they have one model that has two 5-hp
motors/compressors mounted on one air tank. Seems like a good idea, as long as
both motors were somehow staged to not start simultaneously, to minimize
the startup current draw. Anyone familiar with JENNY quality-wise ?
Also, how smart would it be to buy a 3-phase compressor and also buy a
phase converter of some sort ? Too much money for not much return ?
Thanks everyone for your advice on this. I've never had a real good air setup
before in my life, never had the electrical power. I'd like to make a good decision.
