A.J. Antunes JD-2-PURPLE Differential Vacuum Switch

A.J. Antunes JD-2-PURPLE Differential Vacuum Switch is an essential part of HVAC systems that measures pressure variations to optimize the system. It is used to measure the pressure difference between two points which are normally across air filters and blowers. It triggers alerts or initiates system actions as soon as the pressure drop is attained which can be as a result of a filter becoming blocked. It is installed in HVAC systems resulting in equipment protection, improved air quality, and energy savings.
