Purge Setting
The PSA Purge has been set in the factory and should not require adjustment. The purge can be
checked by connecting a simple
Rotameter
type flow meter to the outlet of the drier purge valves in turn.
The connection is for 4mm plastic hose. The correct setting is 12 l/min. This assumes a maximum
generator output of 30 l/min. A reduced purge rate will result in higher levels of contaminate gases over a
period of time.
