Flow Switches Protect Sensitive Equipment

Used to detect the loss of air cooling due to blower failure, dirty air filters, or blocked air intakes, Model E differential pressure switches have dimensions of 2" x 2" x 1.5" and can operate on ultra low pressure of 0.02" of water column and have no detectable ON/OFF switch differential. The switches are often used to replace smaller switches with higher sensitivities. Model E switches have adjustable range of 0.02" to 1.5" column of water. They must be operated with diaphragms in a vertical plane.
