2 Karl Dungs GmbH & Co. - The pressure switch specialists For decades we have been manufacturing pressure switches for a wide variety of applications. The original application field was firing systems followed by air-conditioning and ventilation systems as well as special machine tools. Today you can select a device tailored to meet your specific requirements from one of the largest pressure switch product lines. line overview of pressure switches for gas and air/contents Leaflet numbers Page 2 Short technical overview, conversion tables Page 3 overview Page 4 DDS differential pressure sensor Page Pressure switch as per EN 84 Page 6 Double pressure switch as per EN 84 Page 7 Pressure switch as per EN 84 Page 8 Pressure limiter as per EN 84 Page 8 Differential pressure limiter as per EN 84 Page 9 Vacuum switch as per EN 84 Page 9 Differential pressure switch as per EN 84 Page 0 DUNGS Klima-Set Page Centrifugal switch FW 00 / 2 as per EN 84 Page Pressure switch typeplates Page 2 For more detailed information, please refer to the leaflets listed below Pressure switch product line overview.00 High-pressure, gas and air pressure switches GW.0 Pressure switch GW A4.02 Pressure switch for multiple actuators GW A2.03 Differential pressure switch for air LGW A.04 Differential pressure switch for air LGW A2, LGW A2P.0 Differential pressure switch for air flue and exhaust gases LGW A4, LGW A4/2 (IP 6).07 Pressure switch for gas Differential pressure switch for air LGW C2.
