Product Description
1.5A Air Differential Pressure Switches, 10 KPa DP Switch for HVAC
QAD Series Differential Pressure Switches are designed to sense minute pressure changes and are widely used for controlling aerator flow, monitoring fans and air conditioners. These switches are also suitable for over-heating protection and frost protection in industrial cooling systems. The innovative design allows for visual adjustment of the set point.

Installation Connections
QAD series air pressure controls are factory-calibrated for vertical position. If installed horizontally, this will affect the switching point as follows:
- With cover facing upwards, switching point is 15Pa higher than scale
- With cover facing downwards, switching point is 15Pa lower than scale
Do not install upside down with trip pressures of less than 50Pa!
