Note:
Make gas connections using PTFE tape on all threaded
fittings. Do not use other compounds to seal the threads,
as this can contaminate the purified air.
When making connections from the zero air generator to your piece of

To ensure flow rates within the capacity of the generator, a flow meter should be
