Air Conditioning Filter Drier Specification Example for Camper Conversions: Sealed Unit

This is a worked specification for air conditioning filter drier in a sealed unit 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 sealed unit version exists because the duty cycle on camper conversions 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.

Questions buyers ask

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.

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 the specification be held on file?

Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the ECE R90-compliant build instead of a fresh interpretation.

Do you handle mixed containers?

Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 200 pieces per line.
