Pressure Switch for gas and air
The GAO-, GMH- and GML-A4… ventless pressure switches are adjustable pressure switches for automatic burner controls. These pressure switches are suitable for making and/or breaking a circuit when the medium pressure changes relative to the set point. The setpoint can be set in the field by an adjustable dial with an integrated scale. Test nipple integrated into the metal housing to verify set point.
The GAO-, GMH-, and GML-A4… pressure switch is recommended for industrial and commercial heating, ventilation, and air-conditioning systems.
The GAO-, GMH-, and GML-A4… pressure switch is suitable for dry natural gas, propane, butane, air, and other inert gases. Suitable for up to 0.1 % by volume, dry H^2S.
A “dry” gas has a dew point lower than +15 °F and its relative humidity is less than 60 %.Download Brochure
