I know it says you need 6.0scfm at 90psi and everything I am finding in a 60 or 80 gallon meets those requirements, however being in a small 1 car garage for now, can I do a smaller 30 or 33 gallon compressor with under 6.0 scfm? Or will it not work at all?I am looking to get a cnc in the next few years so wondering how far if at all I can get on a smaller 33 gallon compressor.Torchmate 2x2 CNC with Flashcut CNC controlsHypertherm Powermax45 Esab ET220i Razorweld 195 MigRazorweld 200ac/dc TigTormach 770, Tormach xstechRazorweld, Vipercut/Vipermig, SSC Foot Pedal Dealer
Reply:I can tell you you won't get far on a CNC table with a small compressor. If you just need to cut one or two bolts or some bar stock, you can probably get away with a small compressor.Better choice would be to look at relocating the larger compressor. Some guys will locate it outside the garage in a small shed, or set up a location where they can store it in the attic.You can also get compressed air in cylinders. Though that would be a poor option for a CNC, it would let you do some light cutting before you go whole hog and get a CNC table..No government ever voluntarily reduces itself in size.

Reply:I won't be going cnc until I get a bigger garage so it could be 2-3 years but in the mean time I don't mind getting something smaller to get by.Torchmate 2x2 CNC with Flashcut CNC controlsHypertherm Powermax45 Esab ET220i Razorweld 195 MigRazorweld 200ac/dc TigTormach 770, Tormach xstechRazorweld, Vipercut/Vipermig, SSC Foot Pedal Dealer
Reply:6cfm? A bit too low! With a 2hp motor you can drive a 8 cfm pump on 110/220V single phase. Why you don't just buy a pump, motor, starter and just build one? The receiver (air tank)and air pressure control valve can be install anywhere in your garage, let's say any place over your head...Here a single stage pump giving you 10cfm at 850rpm on a 2hp 110/220V 14XXrpmhttp://www.ebay.com/itm/SCHULZ-AIR-C...item35b6e26e78If you prefer a portable unit buy nothing under a "real" 2hp with a 20gallons+ receiverHere some good candidate:http://www.aircompressorsdirect.com/...sor/p6980.htmlhttp://www.aircompressorsdirect.com/...sor/p6981.htmlMiller MM211Esab Mini Arc 161LTSEsab Handy Plasma 380Duck tapeTy- rapKool-aid
Reply:I don't see why a smaller 30gal-ish compressor wouldn't work. I just got this IR compressor and it delivers 5.2cfm @ 90psi and has 100% duty cycle with IR synthetic oil.http://www.lowes.com/pd_337409-28309-P1.5U-A9_0__I'm sure a larger 30gal+ would suffice just fine.
Reply:Never look at receiver size, always look at compressor output in CFM @ designed pressure. Receivers (like was stated prior) can be located anywhere in the mail piping. Techinically, you can mount the compressor without any receiver and so long as the compressor feeds a mainline, the receiver can be in another room. It don't matter.Compressor manufacturers just use the convenience of a receiver mounted compressor for that reason. You can buy receivers (like Manchester Tank Units) without or with compressor mounting bases. Receivers and compressors don't have to be married units.
