QAD series air pressure controls is used to sense tiny pressure change and widely used to control the flow of aerator, to monitor fan and air conditioner. It is also suitable for over heating protection and frost protection in industrial cooling system. Due to its outstanding design, the setpoint can be adjusted visually.

QAD series air pressure controls is factory-calibrated for vertical position. If installed horizontally, this will affect the switching point as following:
• with cover facing upwards, switching point is 15 Pa higher than scale;
• with cover facing downwards, switching point is 15 Pa lower than scale.
Note: Do not instail upside down with trip pressures of less than 50 pa !
