Hi Neil, Here is a thread with info about how much cfm volume the PalmControl and the foot control are using.
http://www.engravingforum.com/showth...?t=1052&page=2
At shows with the PalmControl I am going through a 20oz paintball bottle a day. Around 8 hours a day. The foot control would probably go through two bottles a day.
Here is a copy from that thread....

I tested the air flow of the foot pedal Classic and PalmControl. The read out is in ml/minute and we need it in CFM (cubic feet/minute). I used this page to help convert the numbers.

Here are the results:
PalmControl set at 35 PSI
Idle: 38.16 ml/min = .001348 CFM
Full throttle: 4333 ml/min = .153027 CFM
Foot pedal set at 35 PSI
Idle: 569 ml/min = .020095 CFM
Full throttle: 4333 ml/min = .153027 CFM
We can average the idle and full throttle together to discover normal usage.
PalmControl normal usage: 2185.58 ml/min = .077718 CFM
Foot Pedal normal usage: 2451 ml/min = .086561 CFM
The stroke adjustment effects the full throttle flow. The above readings were taken with the Classic stroke adjustment at the longest stroke. Both tools use around 2500 ml/min when set at the shortest stroke at full throttle (at 35 PSI). Therefore for average usage of the tools at a short to meduim stroke setting they are using approx .04 to .05 CFM .
