The ADPS/EDPS Adjustable Differential Pressure Switch is engineered to handle pressure, vacuum, and differential pressures with precision. Featuring a dual scaled adjustment knob calibrated in inches water column and pascals, it enables easy modification of switching pressure without the need for a pressure gauge. Offering a wide range of settings from 0.08 in w.c. (20 Pa) to 20 in w.c. (5000 Pa), it caters to various pressure requirements.
Crafted with a silicone diaphragm and PA 6.6 body, the ADPS series is well-suited for applications involving air and other noncombustible gases. For enhanced safety, the EDPS models comply with UL508 standards and are constructed using plenum-rated plastics.
With its compact size, convenient adjustment knob, and economical pricing, the ADPS/EDPS series stands out as an ideal choice for HVAC applications.
