Reznor 203933 SPDT Pressure Switch 0.75" WC

The Reznor 203933 SPDT Pressure Switch is used to control the airflow and pressure in the HVAC system to prevent any dangers. This type of switch operates or switches off circuits depending on pressure differences. The pressure reaches 0.75" of water column to turn the switch on for the appropriate functioning of the system. It is applied in furnaces and heating units to improve efficiency by reducing system failure resulting from pressure. This switch enhances energy consumption and durability of the equipment and is therefore essential in the proper functioning of the HVAC systems.
