Reznor 105507 Pressure Switch

The Reznor 105507 is a pressure switch, which is a critical component in many HVAC systems such as furnaces and air handlers. It serves as a diligent guardian, monitoring air pressure and ensuring that it remains within acceptable limits. Consider it a miniature maestro, autonomously turning on or off the equipment based on predetermined pressure levels. The switch features a sensitive diaphragm that monitors air pressure changes. When the pressure reaches a predetermined level, it completes the circuit and activates the associated equipment. If the pressure goes below the set point, the diaphragm opens the circuit, causing the machine to stop. It optimizes airflow, protects equipment from damage, and even boosts energy efficiency. and three-phase electric furnaces, gas furnaces, and air handlers, quietly functioning behind.
