Adjustable Air Differential Pressure Switch
An adjustable air differential pressure switch designed for HVAC, ventilation, and gas flow monitoring applications. Available in multiple ranges, this compact switch provides reliable airflow and pressure detection for duct systems, filters, and fan protection circuits.
This air differential pressure switch is engineered to monitor pressure differences in air and non-aggressive gas systems. Commonly used in HVAC and building services, it detects airflow presence, filter blockage, fan failure, and duct pressure variations.
The adjustable setpoint allows operators to configure switching thresholds within the selected range (20–200Pa or 30–300Pa), making it suitable for a variety of ventilation and air handling applications.
Designed with a durable plastic housing, the unit is lightweight and easy to install. It connects to ducting via pressure ports and activates a switching output when the preset differential pressure is reached.
This device is widely used for:
-
Air filter monitoring
-
Fan proving applications
-
Duct airflow detection
-
Cleanroom pressure control
-
Gas flow monitoring (non-corrosive gases)
-
Boiler and combustion air systems
