Most P-10 gas systems don’t need constant gas supplies to work properly.  This unit has timers to adjust the flow on and off to keep your instruments sufficiently purged.  The timer can be set from 1-99 minutes.

Operates on 120VAC with 12V power supply.

The Model 1031-1 fails open on a loss of power to keep your instrument purged.  There is a flush button, and a reset button to flush and to re-initiate the timer.
