Rheem-Ruud SP20130 Pressure Switch -0.90" WC

The Rheem-Ruud SP20130 Pressure Switch is vital to the accurate regulation and sustaining pressure in the heated and cool systems. This pressure switch has its water column pressure set at - 0. 90” and its constituent materials include both plastic and metal. Because of its electrical connection type, this probe may be used in any HVAC application. In other words, the switch is well programmed to work in such a way that when pressure is high or low the switch capability of changing pressures is either activated or deactivated. This serves as a protective measure to the equipment as well as possibly damaging the system by shutting of the power as soon as the pressure drops below the require setting.
