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.
