Lennox 65W49 SPST Air Pressure Switch 0.60" WC

The Lennox 65W49 Air Pressure Switch is an essential part made for HVAC systems, which has been designed to control the pressure. This SPST switch works at 0.60 inches of water column to turn on or off the system depending on the pressure. Therefore it improves the safety and effectiveness of heating and cooling in maintaining the air pressure just within the operational safe limit. It is widely used in gas furnace and air handler applications and serves the essential purpose of protecting the system from dangerous ranges by causing the system to stop if it becomes too low. The advantages of this change include increased dependability of HVAC systems, decreased energy use, and increased performance.
