Dungs 248276 GGW10A4 differential pressure switches for air, flue and exhaust gases. Dungs 248276 GGW10A4 pressure switch technical description Dungs GGW10A4 248276 air pressure switch is an adjustable differential pressure switch for automatic burner controls. It is suitable for switching a circuit on, off or over on changes in actual pressure value relative to the set reference value. The reference value (switching point) is adjusted on a setting wheel provided with a scale. The test nipple is integrated in metal housing as standard. Dungs 248276 GGW10A4 differential pressure switch applications Dungs GGW10A4 248276 air pressure switch in furnace, ventilation, and air conditioning applications. Differential pressure switch: Suitable for employment with gas family 1, 2, 3, and other, neutral, gaseous media as well as air, smoke and exhaust gases. Dungs 248276 GGW10A4 pressure switch certifications EC type test approval as per EC Gas Applicance Directive: CE-0085 AQ 0012 EC type test approval as per EC Pressure Equipment Directive: CE0036 Approvals in other important gas-consuming countries. Dungs GGW10A4 248276 differential pressure switch function Dungs 248276 GGW10A4 differential pressure switch operating in the over- and under-pressure ranges. The differential pressure acts on the membrane, pressing it against the force of the adjusting spring and against the microswitch. Dungs GGW10A4 248276 pressure switch operates without outside power.
