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 set point can be set in the field by an adjustable dial with an integrated scale. Test nipple integrated in 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 H2 S.
A “dry” gas has a dew point lower than +15 ¡F and its relative humidity is less than 60 %
