Description
Dungs AA-A1 Differential Air Pressure Switches have an adjustable setpoint (within listed pressure range) and a compact pressure switch for automatic gas burning equipment controls. Available with hose connections.
The Dungs AA…A1 series differential pressure switches are suitable for making and/or breaking a circuit when the medium pressure changes relative to the set point. Applications can be differential pressure monitoring in firing, ventilation and air-conditioning systems.
The Dungs AA…A1 can be used as a pressure, vacuum or differential pressure switch for air and non-aggressive gases. Not suitable for natural gas, propane, butane, and other combustible gases.
