The Process

Pre-treated compressed air enters the active column of the generator and follows up through the molecular sieve. The undesirable gases are being adsorbed while the oxygen passes through to buffer tank. When the pressure is released the molecular sieve completely regenerates and the adsorbed gases are led to exhaust. Oxygen from buffer tank is boosted at high pressure to the filling ramp and cylinders are filled.


The filling station compact is preferred solution in remote areas where commissioning of classic filling station is considered difficult or transportability is needed.
