Airless Spray Gun Specification Example for Agricultural Trailers: Quick Fit Version
Airless Spray Gun Specification Example for Agricultural Trailers: Quick Fit Version
This is a worked specification for airless spray gun 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 agricultural trailers is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a supplier who changed material without saying so.

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.
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.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 200 pieces per line.
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.
Tell us the model, the fitment and the quantity and we will hold a production slot for you.
