Air Filtering, How to keep the pressure low?

[German_Customs]

Heyo!

I figured out how to filter air and create an airmix for my station, which gets trough an ac for smooth temperature. BUT the air has to be filtered constantly, at least oft enough to breathe a nice mixture. It goes trough my system (with connected tanks for each gas) and everything is ok but what is when my tanks are full (my set pressure is reached).. ? The pipes are gonna build high pressure til they blow up / i stop air filtering and die / i let the gas which is too much escape and i loose pressure.

Maybe some 1 can give me the push to the right solution.. :-(

there is this item called Pressure Regulator
maybe that's what you're looking for

I don't totally understand everything about your system. But it sounds like you're saying your problem is, when you send your airmix pipe gases (which are the same pressure as what's in your base) somewhere else, you lose that pressure and thereby lose pressure in your base. I think what you want is a backpressure regulator. What this does is only send something out of a pipe when the pipe pressure will go beyond the setting. So if you want to maintain 1 atmosphere (101 kPa) in a pipe, you put a backpressure regulator on it, which tells the pipe network, never let this pressure drop below 101 kPa. Maybe something like that placed somewhere will work for you.
