Description
The A.J. Antunes 8021203119 Differential Air Pressure Switch is an essential part of HVAC systems to some of the air pressure differences across some of the elements such as filters, coils as well as dampers. It works on the concept of measuring pressure variation between two points in the system. The pressure differential is above a set point, the switch turns on and sounds an alarm or starts a control system to alter the airflow or take other appropriate actions. This helps to get the better out of the system, protect the equipment and enhance energy utilization. The switch is highly utilized in a wide array of HVAC equipment, cooling systems, air handling units, chillers, and cooling towers.
