SYR Filling Combination BA 6628, DN20 with thermal insulation shell, made of pressed brass

The FüllCombi BA 6628 is used for the automatic filling and refilling of hot water central heating systems in accordance with DIN EN 12828. According to DIN EN 1717, it is permanently connected to the drinking water pipe. If the supply pressure falls below the pressure of the heating system during the filling process, the BA backflow preventer (approved up to and including fluid category 4) integrated in the FüllCombi prevents the heating water from flowing back into the drinking water pipe. Even heating water with inhibitors (corrosion and antifreeze agents) can be permanently connected to the drinking water installation with the help of the FüllCombi BA, thus eliminating the previously common hose connection. After the filling process, the shut-off of the FüllCombi BA should be closed again for safety reasons.
The FüllCombi BA 6628 consists of a shut-off valve, pressure reducer, manometer, BA backflow preventer and waste water connection. It thus contains all components for standard-compliant filling of a heating system.
