Presair is a leading manufacturer of both adjustable pressure switches and factory set pressure switches. Our field adjustable pressure switches allow our customers the flexibility of easily setting the switch parameters in the field as driven by the needs of the project. Adjustable pressure switches span the range of pressure from 0.25 inches of water gauge to 125 psig. Pressure switches can be adjusted by rotating the hex screw located at the center of the pressure switch.
Presair’s adjustable pressure switch is field adjustable from 1.5 inches of water to 125 Psi. The adjustable range is 10% to 25% lower on falling pressure, although special differentials are available. Dual pressures switches available and can be factory set to allow each snap action switch to operate at a different pressure setting.
These switches allow for simple electrical on/off control over pressures and vacuums. As pressure goes up, one contact opens as the other closes. This provides a perfect solution for monitoring, controlling, and notifying.
