Hello All,
I have an MPS C3 Booster, my supply of endless drive gas has dried up and I'm now resorting to driving from cylinders, (not much fun) I'm currently on the look out for a low pressure compressor to drive it. Does any one have any information on the liters per minute (or CFM) it requires for optimum running?, I know it's thirsty so I want to get this right. Manufacturer's info seems to be a bit thin on the ground so far.

As I'm not familiar with the booster, and you allready have the setup...
Do a worst-case boosting with:
Low supply pressure
High Boost-pressure
Meassure the pressure-drop on you drive-tank over say 5 mins.
Calculate drive-flow form this.
Get a compressor thats at least 30% bigger than this in effective flow.
---------
Otherwise do a rough calculation based upon:
'stroke-volume of drive-poistion' x 'Cycles/min' x 'Maks Drivepressure' x 2
The last factor 2 is if your booster uses drivegas in both compression and return-stroke.
Remember to add a safety-factor to your actual purchase, and that its real-life performance of the shop-compressor at the highest pressure thats relevant.
Example - For my HII 5G-SS-30-OT thats something like:
1.5l/stroke x 20stroke/min x 10bar = 300 l/min
I run it even slower than this, and the
'-T' option doesn't use gas on return-stroke.
