Senasys Releases Low Cost Adjustable Vacuum Alarm to Help Prevent Significant Downtime

Be Alerted when Vacuum Rises or Falls in your System with Presair’s Vacuum Alarm.

Eau Claire, WI (December 15, 2021) — Presair, a division of Senasys, a well renowned manufacturer of pneumatic pressure and vacuum switches, recently released a cost effective and efficient device to monitor the amount of vacuum in an airline.

Much like the pressure alarm Senasys manufactures, the vacuum alarm is designed to grab the attention of qualified personnel to prevent and fix issues before they cause significant downtime.
This 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 or rises above your specified set point. A protective switch boot keeps connections safe and damage free.
The switch action is SPDT/SPST, and is UL & CUL rated for 100,000 cycles at 5 Amps @ 240VAC. The adjustable vacuum switch has a range of 2.5 - 300 Inches of Water and a differential vacuum of ± 10 Inches of Water. Add-ons such as magnets for easy mounting are also available. This vacuum alarm is MADE IN THE USA.
The vacuum switch is field adjustable by using a Phillip's head screw on the microswitch carrier and can be set anywhere between the range you select. All switches are 100% tested at high and low settings and at proof pressure tested.
