A missing or cracked exhaust cover on a Windsor Sensor is not cosmetic. It is what holds the exhaust filter flat against the housing, and without it the filter shifts, dust bypasses the media, and the machine blows grit back into the room it just cleaned. This is the replacement exhaust filter cover for Windsor Sensor S12 and S15 commercial uprights, the wavy blue panel that snaps over the exhaust filter. Building-services managers order it whenever a cover is broken by a cart, a doorway or a stairwell drop.
Built for these use cases
- Replacing a cover cracked or lost during daily route cleaning
- Bringing a used or fleet-transferred Sensor S12 or S15 back to complete condition
- Keeping exhaust filtration sealed so dust is not blown back onto cleaned floors
- Scheduled preventive maintenance rebuilds on a fleet of Sensor uprights
- Restoring a machine before resale or return from a leased contract
Fit and compatibility
This is the exhaust filter cover for the Windsor Sensor S line, listed as position 102 in the Sensor S service parts manual and referenced as 2820BL, 86141380 and 8.614-138.0. It fits the S12 and S15 sizes. The exhaust filter that sits under it is a separate part at position 101 and is ordered on its own. Sensor covers have been produced in more than one color over the production run, including gray versions on later machines, so match by part number and by the wavy profile rather than by color alone. If the cover on your machine slides rather than snaps, you are likely looking at a different Windsor model and should check the manual for that unit.

Installation and care
- Unplug the machine before removing the old cover.
- Lift the exhaust filter out and inspect it while the cover is off, since a broken cover usually means the filter has been running loose.
- Clear grit from the cover seat so the new panel snaps flat with no gap along the edge.
- Seat the filter first, then snap the cover on, checking that it holds without finger pressure.
- Add the cover check to the same walk-around inspection used for the belt and brush roll.
On a nightly route, the fastest way to catch a broken cover is at the machine's own exhaust: if a Sensor starts leaving a fine dust line along baseboards where it parked, the exhaust path is not sealed and the cover is the first thing to check.
Frequently asked questions
Which machines does the 2820BL cover fit?
Windsor Sensor S commercial uprights in the S12 and S15 sizes. It appears as position 102 in the Sensor S service parts manual.
Does the cover include the exhaust filter?
No. The filter itself is a separate part, listed as position 101 in the same diagram. If your cover was broken, it is worth replacing the filter at the same time.
Can the machine be run without the cover?
It should not be. Without the cover the exhaust filter is not held in position, so unfiltered air escapes around the media and the filter can fall out during use.
How is it installed?
It snaps over the exhaust filter opening on the vacuum body. No tools or fasteners are required.
Is 86141380 the same part?
Yes. 2820BL, 86141380 and 8.614-138.0 all refer to this same Sensor exhaust filter cover.
