A.J. Antunes JD-2-GREY .1-4 Inch Wc Dif-Vac-#, Pressure Sw.

The Honeywell A.J. Antunes JD-2-GREY Pressure Switch is a critical component used in HVAC systems for accurate pressure management. This switch monitors and controls pressure differentials to provide maximum performance and safety within a pressure range of 0.1 to 4 inches of water column. Installed in HVAC equipment, including air handling units, boilers, and furnaces, it is essential for avoiding over- or under-pressurization, which protects the system from potential damage and guarantees effective functioning. The switch contributes to improved HVAC system performance, lifespan, and energy economy by sensing changes in pressure and initiating the proper reactions to maintain optimum levels.
