Air flow pressure switches and differential pressure switches work just like the light switches we have in our living rooms at home: when they are switched on, the switch makes contact, closes the circuit, and turns on. When they are switched off, the circuit is broken and power turns off. With air flow switches, instead of being manually switched, the air flow switch closes or opens the contact by reacting to changes in the air pressure at a pre-set actuation point, and turns on and off accordingly. These air pressure switches may be used to start/stop motors or fans, open/close dampers or louvers, sound alarms, and more. Continue reading “Let’s Chat About Air Pressure Switches!”
Question: What setpoint should I set my differential pressure switch to for indicating when my filter is dirty?
Question: Is there a kit I can buy with the Magnehelic® Differential Pressure Gage for monitoring air filters, so that I don’t have to buy all the tubing, static pressure tips, and a bracket separately?
