Anyone good with compressors and air consumption?.. most compressors here are rated at litres per minute at 6 bar (equivalent to cfm at 90psi).
The Hit-M needs from 175 lpm (6cfm) at 0,9 bar (13psi) up to 283 lpm (10cfm) at 0,6 bar (9psi) - I can't work out compressor requirements from this.
I'm assuming it's not linear, so a compressor putting out 80lpm (3cfm) at 6 bar (90psi) - that's not 480 lpm at 1 bar?
Also, 1 bar Is atmospheric pressure, so how can a compressor put out lower than this?.. or air requirement be lower than this?
Just to add to the confusion, how does altitude make a difference to air requirement?

I vaguely remember being told to derate my compressor the one time I worked on a cabin in the mountains. After a brief search that does seem to be the case LINK

Interesting, thanks. Lots of conflicting info about compressors on the internet. Never had the need to really understand - it's pretty straight forward for a nailer! The Hit-M needs about 2cfm at standby to keep the temperature, but it's the 10cfm at 9psi - I can't understand how that equates to a compressors output that is rated at 90psi.

Apparently the Hit-M needs 283 litres per minute at 6 bar - 0,6 bar is the output at the nozzle.
