Description
The Lennox 59W74 Air Pressure Switch is an essential part used in HVAC systems that work with pressure of 0.80 inches of WC and uses SPST. This switch works with the aid of measuring the pressure of the air inside the system the system switches on or off depending on the pressure. This is beneficial so that different systems run smoothly and safely this means that there cannot be system failure because of low-pressure. This is especially true in uses like gas furnaces and other heating systems where the proper flow of air must be closely controlled for safety and efficiency. This switch also helps in maintaining the right pressure hence increasing efficiency, decreasing, and the durability of HVAC systems.
