Be Alerted when Vacuum Rises or Falls in your System with Presairs’ Vacuum Alarm.
You’ve heard of our Presair Pressure Alarm but did you know we can also do a Vacuum version?
Presairs’ Vacuum Alarm is a perfect way to be alerted when vacuum rises or falls in your system.
By Pairing a vacuum switch with a quick connect coupling, this allows for effortless setup. A magnetic stack light and/or alarm connected to the switch alerts personnel as soon as the airline drops below your specified inH2O. A protective switch boot keeps connections safe and damage free. Not only will this save you time, but money too! Never miss a line down again!
The switch
In this application, we used Presairs’ adjustable 
vacuum switch. Its broad range of setting vacuums and high proof pressure rating provided the ideal switch for monitoring airline vacuum. A form-fitting switch boot, made from soft PVC, provides a layer of protection for the wiring terminals of the switch.
