Reznor 193806 SPDT Pressure Switch 0.20" WC

The Reznor 193806 SPDT Pressure Switch is used in HVAC systems to measure pressure. It is equipped with a Single Pole Double Throw switch and has an operational pressure of 0.20" of water column for controlling the system. This switch is applied in furnaces, air handlers, and other heating or cooling equipment to prevent the equipment from working at a pressure level that is beyond the recommended range. Some of the benefits include improved energy efficiency, longer system durability and protection from pressure variations that may cause the system to fail.
