The Series ADPS/EDPS Adjustable Differential Pressure Switch is designed for pressure, vacuum, and differential pressures. The dual scaled adjustment knob in inches water column and pascals allows changes to the switching pressure to be made without a pressure gage. The ADPS/EDPS is available with settings from 0.08 in w.c. (20 Pa) up to 20 in w.c. (5000 Pa). The silicone diaphragm and PA 6.6 body make the series ADPS ideal for use with air and other noncombustible gases. Series EDPS models meet UL508 and are constructed of plenum rated plastics. The compact size, adjustment knob and low cost make the ADPS/EDPS the perfect choice for HVAC applications.

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 15Pa higher than scale;
• with cover facing downwards, switching point is 15Pa lower than scale.
Note: Do not install upside down with trip pressures of less than 50pa!
