Description

General

The GGAO-A4… ventless differential pressure switch is an adjustable, gasto-gas differential pressure switch for automatic burner controls. These pressure switches are suitable for making and/or breaking a circuit when the differential pressure changes relative to the set point. The set point can be set in the field by an adjustable dial with an integrated scale. Test nipple is integrated in metal housing to verify set point.

Application

The GGAO-A4… differential pressure switch is recommended for industrial and commercial heating, ventilation and air-conditioning systems. The GGAO-A4… differential pressure switch is suitable for dry natural gas, propane, butane, air and other inert gases. Suitable for up to 0.1 % by volume, dry H2 S. A “dry” gas has a dew point lower than +15 °F and its relative humidity is less than 60 %.
