HVAC Differential Pressure Switch
HVAC Differential Pressure Switch
Controls and Engrs offers HVAC Differential Pressure Switch, Series ADPS. This is designed for pressure, vacuum, and differential pressures. The dual scaled adjustment knob in inches water column and Pascal allows changes to the switching pressure to be made without a pressure gage. The ADPS is available with settings from 0.08? WC (20 Pa) up to 16? WC (4000 Pa). The silicone diaphragm and PA 6.6 body make the series ADPS ideal for use with air and other non-combustible gases. The compact size, adjustment knob and low cost make the ADPS the perfect choice for HVAC applications.
