Vacuum Alarm Switch

SUPERIOR™ Digital Chlorine Vacuum Alarm Switch(VAS)

SUPERIOR Series VAS chlorine vacuum alarm switches are designed to alert gas chlorinator users when either of two critical situations arise:

HIGH VACUUM ALARM – indicates that the supply of chlorine gas has been interrupted. Either the chlorine supply is empty, or the chlorine cylinder valve has been shut off. In either case there is no chlorine gas entering the system.
LOW VACUUM ALARM – indicates that the ejector is not producing sufficient vacuum to operate the system, or a leak has occurred somewhere in the system.
