Air Auto Filter Specification Example for Dealership Service: Reinforced Build
Air Auto Filter Specification Example for Dealership Service: Reinforced Build
This is a worked specification for air auto filter in a reinforced build programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.
The reinforced build version exists because the duty cycle on dealership service is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a fitment that looked right on paper and failed on the bench.

Example specification
| Item | Air Auto Filter |
|---|---|
| Application | Dealership Service |
| Version | Reinforced Build |
| Base material | Anodised Aluminium |
| Controlled dimensions | 5 key dimensions, recorded per lot |
| Tolerance band | ±0.05 mm |
| Finish | painted |
| MOQ | 200 pieces per specification |
| Sampling | 14 working days, 3 days per revision |
| Compliance | RoHS |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Anodised Aluminium, in this example.
- List the dimensions that are actually controlled and the tolerance on each.
- Name the finish and what it has to survive.
- State the inspection level and who pays when a lot fails.

Processes involved
- electroplating
- anodising
- sintering
- rubber vulcanisation
- precision stamping
- shot blasting
Where this example applies
Programmes that run reinforced build most often specify this build for dealership service. Related applications include city buses, fleet maintenance, construction equipment, scooter fleets, long-haul trucks.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 1.5 sampling on the finished lot.
- Finish inspection under agreed lighting.
- Carton drop test on the first lot of a new packing specification.
Questions buyers ask
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the RoHS-compliant build instead of a fresh interpretation.
What testing is included?
Standard lots ship with dimensional and hardness reports. RoHS documentation is issued with the shipment when your market requires it.
What is the minimum order quantity?
The standard MOQ is 200 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 200 pieces per line.
