Drone manufacturers in the Kingdom run into a conceptual trap: the part is small, so the chamber is assumed small and the requirements lighter. The first is true and the second is not.
A drone airframe finishing booth is sized by the part, but judged by aerospace standards — and those are two different things.
Size follows the batch
Airframes, wings and components are processed in counts rather than one at a time. Design therefore starts from parts per cycle and how they are hung, and internal size is derived from that.
The published range starts at 3000 mm long, below vehicle size, so it takes these applications comfortably — and usable volume is set by racking rather than by dimensions alone.
| Input | Effect |
|---|---|
| Parts per cycle | Internal size and usable volume |
| Largest airframe or wing dimensions | Minimum length and height |
| Racking method | Row spacing and air reach |
| Coating material | Heat curve and filter class |
| Your authority’s acceptance requirements | Filtration level and documentation |
Why the filter class rises as the part shrinks
A small surface is less forgiving, not more. A composite airframe shows any trapped particle clearly, and acceptance in aerospace is measured by repeating a result and documenting it.
Published filtration starts with stop, pre and ceiling stages at EU3, EU4 and EU5, extending to three-stage bag and high-efficiency filtration at ≥98% where the work requires it.
Reach between rows
Spacing between hung parts decides whether air reaches the inner part as it reaches the outer one. Rows set too close produce variation inside a single batch — a defect that shows at inspection rather than at spraying.
Preparation before finishing
These parts carry a preparation and inspection stage ahead of finishing, with extraction requirements different from spraying. A separate prep room with its own extraction precedes the finishing chamber where the site allows it.
Frequently asked questions
Do drones need an aircraft-sized chamber?
No. Size follows the largest part and parts per batch, and the published range starts at 3000 mm long. Filtration and documentation requirements follow the sector rather than the size.
What determines my filter class?
Your coating material and your authority’s acceptance requirements together. Send both so filtration is built on them rather than carried over from another application.
Can airframes and wings share one chamber?
Yes, if internal length takes the longest part and racking allows both. Send the range of sizes on your line so the arrangement is built on the range rather than one part.
Can you issue a specification fit for tenders?
Yes. We issue written technical specifications with the required conformity data so they can be inserted directly into a competition or contract without redrafting.
