The cycle time could be up to continuous. The size constraints are based upon gas volume inside the blower. Preferably, the application needs a blower with less than 125cc blower internal volume.
It is looking like the application will need something like a very high speed centrifugal...
Interesting, I was considering a fan in the pressurized system. However, energy usage by the blower is a bit of an issue so I am not sure about the efficiency of a fan designed for ambient pressure air.
Of the limited success that you've had, what have you tried and what has worked best?
Folks,
I am looking for a blower to produce a flow of ~150cfm (~4m^3/min) while pumping H2 pressurized at ~40bar. The blower needs to provide a pressure increase of ~5bar.
I am wondering if something like a supercharger blower might work.
