Which air compressor?

**m_c** · 13-11-2011

200l/min is roughly 7cfm.
That compressor will be rated at 30cfm free air delivery.
So with a bit basic physics (boyle's law) and given that you need 7cfm at 70psi, which is roughly 5 times atmospheric pressure, means that compressor could deliver about 6cfm at 70psi.

Does the dugard need that amount of air continually?
If it does, than that compressor is undersized, but I can't see what on a VMC would need that amount of air continually, unless it's using a mister.

Thanks for your reply m_c, I'll contact dugard to see if that machine requires it continously but i have a feeling it does. I use a Haas VMC at work which alarms out if air pressure falls below 80 PSI.

I may need to spend a bit more on a compressor i think! I'll let you know how i get on. Thanks
