Product details
Part 7020ER is the bag-full display assembly for SEBO's D-range canisters, supplied as the indicator together with the spring that calibrates it. Fitment: SEBO AIRBELT D1 TURBO and SEBO AIRBELT D4 PREMIUM. The two pieces are catalogued as one item rather than separately, because the spring is not an accessory to the indicator — it is the reference the display reads against.
The gauge measures pressure difference, not dust volume. Suction on the motor side of the filter bag works against spring tension, and as the bag loads up, restriction climbs and the mechanism travels across its scale. That makes the spring the calibration itself: let it fatigue, unhook or corrode and the window can sit at empty while a packed bag hides behind it, or read full on a bag that has covered one room. Neighbouring positions on the AIRBELT D parts drawing complete the picture — item 33 is the bag indicator adjuster 8127ER, the separate trim adjustment for this display, and item 23 is the filter bag spring 8140ER, which holds the bag collar to its seat. Both carry the same D1 TURBO and D4 PREMIUM listing as this assembly.
Diagnose in that order. A blocked hose, wand or nozzle raises restriction just as a full bag does, so clear the airway first and only then judge whether the display is telling the truth. If it still reads wrong with a fresh bag and a clear path, the indicator and spring are the answer.
