RA18759 Robinair Air Purge Gauge And Thermometer gives the operator a visual cue as to the air content of a cylinder during recycling mode. Operates on a pressure temperature equivalence similar to a pressure temperature chart. The temp scale reads from the red needle and the pressure scale reads from the green needle. All that is needed is to compare the needles on the gauge to determine if air is present.
Robinair does not warrant any "RA" repair item not installed by an Authorized Service Center.
