The Presair Differential pressure Switch is a series of sensitive single pole switches that can be used as pressure or vacuum switches, or as differential pressure switches.

The Presair Differential Pressure Switch can monitor the difference between two systems. Sensing a low range of pressure, these single pole single throw differential pressure switches monitor air pressure in sensitive environments and sense when low pressure occurs. Sensitive differential switches are weatherproof and explosion proof can be factory set or adjustable simplified calibration.

Presair Sensitive Differential Pressure Switches cost is comparable or lower than conventional controls to meet the needs of the original equipment manufacturer.
