I need to design a system using gas boosters with dual pistons to control the pressure. I'm not really familiar with gas boosters, but I have a vague idea how they work, however, I've only ever used them with a constant pressure in. Unfortunately, this system uses a manifold to supply the gas, and the manifold is not at a constant pressure. Can anyone think of any ways to use the gas booster and control the pressure so that it is a constant pressure going in and coming out?
