Air Conditioning Filter Drier Specification Example for Three-Wheelers: Quick Fit Version
Air Conditioning Filter Drier Specification Example for Three-Wheelers: Quick Fit Version
This is a worked specification for air conditioning filter drier in a quick fit version 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 quick fit version version exists because the duty cycle on three-wheelers is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually inconsistent hardness between lots.

Example specification
| Item | Air Conditioning Filter Drier |
|---|---|
| Application | Three-Wheelers |
| Version | Quick Fit Version |
| Base material | Chromed Steel |
| Controlled dimensions | 5 key dimensions, recorded per lot |

| Finish | zinc plated |
| MOQ | 2,000 pieces per specification |
| Sampling | 10 working days, 5 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 — Chromed Steel, 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
- die casting
- robot welding
- anodising
- CNC machining
- surface grinding
- assembly line testing
Where this example applies
Programmes that run quick fit version most often specify this build for three-wheelers. Related applications include fleet maintenance, three-wheelers, utility trailers, camper conversions, rental motorcycles.
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
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 happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
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.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 2000 pieces per line.
Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
