I have a Belt drive Jetair J11 50l 3hp 11CFM and was looking at getting another to run of similar spec along side to increase the CFM for sodablasting and etc. Just unsure of the actual output with that setup or if even the one i have give the spec it says. Now i have just found a 150l 3hp 14cfm not bad price at £200 with a new motor fitted aswell. Oh nd cant go spending much more and on single phase and can run two separate sockets aswell if need be for 16amp. Although the 3hp i have runs fine on 13amp. Thoughts please.
