Darker AIRBELT E3 Premium bodies take the graphite finish, and 8224GSER is the filter compartment panel in it. This is the moulding as SEBO builds it rather than a trim piece laid over a damaged one, so the repair leaves the machine genuinely sound instead of tidied up.Pressure is what this panel supplies. Air only goes through a filter that is held against its landing across the entire face, and the clamping force comes from the cover and the handful of bosses and clips anchoring it. Crack one boss and the force on that side falls away. Nothing announces the change — the motor sounds identical, the filter looks clean, and yet a share of what the machine picks up returns to the air. Renewing the cover puts uniform load back across the whole media.Each finish on this canister carries its own number rather than a shared one with a colour option, so ordering is a matter of matching the code. Beside graphite, the AIRBELT E3 Premium takes 8224SWER in black, 8224DRER in red, 8224WEPRER in white, and the three pastels 8224CIER, 8224CMER and 8224CZER. Fits: SEBO AIRBELT E3 Premium Part number: 8224GSER Colour: graphite Job: clamps the media to its landing and closes the bay Tell-tale: fine dust settling near the machine while the filter itself still looks clean Other finishes for the same canister: 8224SWER black, 8224DRER red, 8224WEPRER white Two symptoms send people to this number. The first is obvious damage — a split panel, a catch that will no longer hold, a hinge tab found loose in the bay. The second is subtler and easier to misread: a machine that has quietly stopped holding on to fine dust, with a filter that looks perfectly clean when it comes out. Check the cover for hairline cracks around the fixings before condemning anything more expensive.Genuine SEBO stock; dispatch inside 2–5 business days.
