Mechanical Vacuum Switches
Dual Vacuum Controllers
These units can run two vacuum pumps in a lead lag configuration.
Also suitable to monitor vacuum at the point of use.
-1 to +1 bar range. Will withstand a pressure of 3 bar.
Power supply 12 to 24 Volt DC. Current consumption is less than 55 mA.
What is a Vacuum Switch?
A vacuum switch is an electronic or mechanical device that provides an electrical switching contact function at a defined vacuum gas pressure level. It’s used in many vacuum applications for pressure control purposes and safety interlock functionality.
Vacuum switches are an essential component for many monitoring and control applications in hydraulic, pneumatic and processing industries. Performing in critical processes, these switches sense a change in the vacuum and open or close an electrical circuit when the chosen setpoint is reached.
What are Vacuum Switches used for?
A Vacuum Pressure Switch operates by comparing the relative pressure between your process pressure and a vacuum.
The benefit of this technology is the ability to measure pressure below your local atmospheric pressure. To accomplish this, a vacuum switch has a sealed reference chamber, as well as a diaphragm and a Belleville spring to actuate when your pressure setpoints are reached.
Refrigerated air dryers from 750 liters/min up to 17000 liter/min ex-stock. Larger ex overseas. Dew point 4°C under pressure. Automatic drain pre and manual drain after filters.
Screw compressors have no valves or other mechanical forces to cause imbalances unlike piston compressors.
Airpower keeps universal spare parts for compressors. Pressure switches, non return valves and safety valves are universal to all compressors. Bottom entry filters/ regulators, electric motors and starters can be used for many makes of compressors.
