Cabin Blower for BMW 3 Series: Powder Coated Steel
This cabin blower for the BMW 3 Series is specified around powder coated steel, which decides how it behaves in service far more than the part name does. We build to a written specification — base material, dimensions, finish and packing — and hold that specification on file so every reorder reproduces the approved piece.
The usual reason a programme changes supplier is not unit price. It is warranty claims traced back to a single lot, or lead time that slipped twice before bulk started. Both are specification problems, and both are preventable.

Fitment notes
Confirm the fitment against the VIN or the frame number before ordering; two model years often share a name and not a part.

Quality and packing
- In-line inspection with AQL 1.5 sampling on every lot.

- Carton marking and barcode to your specification.
- Golden sample retained at the factory as the reorder reference.
Questions buyers ask
Can you match an existing sample?
Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the SAE J431-compliant build instead of a fresh interpretation.
How long does sampling take?
Samples leave the factory in 7 working days, and each revision round adds about 3 days once you have seen the first piece.
What testing is included?
Standard lots ship with dimensional and hardness reports. SAE J431 documentation is issued with the shipment when your market requires it.
Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
