Some advise needed, unusually big air compressor want to run a smaller tool

[Galea1]

Hi All,

Got a 105cfm @ 100psi 2 cylinder petrol driven rotary screw; and I would like to power a vacuum abrasive blaster, the blaster manual says that air requirement are 80-120psi @ 20 cfm.

Compressor is significantly oversized.

A bit skeptical, firstly its my first time having a going to sandblasting and secondly the compressor is not industrial/commercial powerfull enough to power proper blast pots, but it seem stoo big to power a diy blast pot, any way around it?

all input to avoid getting another compressor are helpfull.

Thanks

Your blaster will draw what it takes and no more - it'll be fine (but expensive to run)

It's like a normal 13 amp electrical socket - things plugged in don't need to draw the full 12 amps !!!!

well over powered but not a problem just more fuel to use. if you have the gear you could increase your blast jet size giving a greater coverage

you can run a 6mm blast jet on 105cfm no problem
