Description
The Weil McLain 511-624-657 Pressure Switch is an essential component in HVAC systems. This switch monitors and controls air at a pressure of 1.36″ WC to prevent unsafe or inefficient operation. It turns on or off circuits according to pre-set thresholds to prevent equipment damage. It is commonly used in boiler units for safety and system performance. The pressure sensing is accurate enough for optimal combustion, saves energy and promotes durability. The operation of this part is essential to maintaining consistent operation in heating applications.
