Series EDPS HVAC Differential Pressure Switch

Meets Standard UL508, Housing Materials UL94 V-0 Rated

The Series 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 EDPS is available with settings from 0.08" w.c. (20 Pa) up to 16" w.c. (4000 Pa). The silicone diaphragm and PA 6.6 body make the series EDPS ideal for use with air and other noncombustible gases. The compact size, adjustment knob and meeting the UL508 standard make the EDPS the perfect choice for H.V.A.C. applications.
