BDPA

EDPS

The Series ADPS/EDPS/BDPA HVAC Differential Pressure Switches are 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/BDPA are 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 series

BDPA Adjustable Differential Pressure Alarms offer a versatile range of congurations allowing utilization of their many features including buzzer and LED notication, and

battery or line powered. The compact size, adjustment knob and low cost make the ADPS/EDPS/BDPA the perfect choice for HVAC applications.

BENEFITS/FEATURES

• Adjustment knob changes switching pressure easily with a pressure gage reducing components for application

• Low cost device makes it an excellent solution in BAS and HVAC applications requiring duct control and monitoring

• Relay contact allows simple integration with DDC or building systems

APPLICATIONS

• Air lter and ventilator monitoring

• Industrial cooling circuits

• Fire-protection damper control

• Ventilation duct monitoring

• Fan heater overheating protection

• Heat exchanger frost protection
