Hi Richie,

Very interesting,
I've bought a HII 5G-SS-30-OT, which is quite big for my purpose....
But I've only yet done trst-runs with it.

Both the Haskel and the HII seems to only use drivegas on the compression-stroke of the cycle. Therefor its the boostgas supply-pressure the drive the other half of the cycle (In HII-speak this is modification type T).

Regards
Nicolai

The Haskel uses the drive gas for both sides of the cycle. It's a double action booster. Some of the others are single action and use the boost gas for half the cycle. That may be another plus for the unit.
