Air Differential Pressure Switches

Air Differential Pressure Switches


Air Differential Pressure Switches are crucial components in HVAC systems, ensuring optimal performance by monitoring and controlling the differential pressure of air across two points. These switches are designed for reliability and precision, making them indispensable in both industrial and residential settings.

How They Work

Our air differential pressure switches operate by sensing the pressure difference between two air sources. When this differential exceeds a preset threshold, the switch activates, triggering a response such as turning on a fan, shutting off a system, or activating an alarm. This functionality is essential for maintaining air quality and ensuring efficient operation of heating, ventilation, and air conditioning systems.


  • HVAC Systems: Enhances system efficiency by regulating air flow and maintaining designated air pressure levels.
  • Clean Rooms: Maintains necessary pressure levels to prevent contamination.
  • Industrial Ventilation: Ensures proper ventilation by adjusting airflow based on pressure changes.
  • Safety Applications: Activates alarms in case of significant pressure drops or rises, indicating potential system failures.

Features and Benefits

  • High Sensitivity and Accuracy: Ensures precise pressure monitoring, leading to better system control and reduced energy consumption.
  • Durability: Built to withstand harsh environments and provide reliable performance under varying conditions.
  • Easy Integration: Compatible with most HVAC systems, allowing for straightforward installation and maintenance.
  • Customizable Settings: Adjustable thresholds to meet specific application requirements, ensuring flexibility and optimal performance.
