Air Conditioning Filter Drier Specification Example for Workshop Replacements: Standard Replacement
Air Conditioning Filter Drier Specification Example for Workshop Replacements: Standard Replacement
This is a worked specification for air conditioning filter drier in a standard replacement 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 standard replacement version exists because the duty cycle on workshop replacements is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a specification nobody had written down.

Programmes that run standard replacement most often specify this build for workshop replacements. Related applications include utility trailers, workshop replacements, delivery vans, emergency vehicles, trailer axles.
Checks before packing

- 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
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 1000 pieces per line.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the E-mark-compliant build instead of a fresh interpretation.
How is packing specified?
Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.
What testing is included?
Standard lots ship with dimensional and hardness reports. E-mark documentation is issued with the shipment when your market requires it.
