Length is the figure asked about first. Width is the one forgotten and then discovered on site — because a part enters on its length but is coated across its width, and the technician moves around the width rather than the length.
An internal width to 20 metres is the upper end delivered in this family, against a lower end of 3000 mm — a range that widens close to sevenfold between its ends.
What sits at each end
| Position in the range | Size | What it serves |
|---|---|---|
| Lower end | 3000 mm | Powder coating curing cabins for industrial parts |
| Automotive footprint | 4000 mm wide in INTECH models | Passenger cars and SUVs |
| Trucks and buses | up to 6500 mm | Buses and long vehicles |
| Upper end | up to 20,000 mm | Large-structure cabins |
Width and length do not move together
Internal length delivered runs 3,000 – 24,000 mm and width 3,000 – 20,000 mm. Maximum length is therefore close to double maximum width, because length is usually driven by how far a part extends while width is driven by its lateral spread plus the technician’s working space around it.
Why width is measured on the part, not on the room
Internal size is fixed from the dimensions of the part to be coated plus the technician’s working space around it. A chamber wide enough for the part alone puts the technician up against the surface, and that changes spray quality before it changes anything else.
Frequently asked questions
Does greater width mean greater air capacity?
Indirectly, yes. Air capacity is built on chamber volume, and the delivered range runs from 18,000 to 190,000 m³/h per supply or extraction set — the upper end serving those same large-structure cabins.
What door size goes with this width?
The published main door range runs from 3000×2600 mm to 14,200×5,000 mm powered. The door is measured on the widest and tallest section passing through it.
Does this width serve furniture and timber?
In woodworking and furniture the size follows the largest piece of furniture rather than a vehicle, and any required size is built to suit the part and the production line — inside the same published range.
How is the required width calculated for a site?
Start from the widest part to be coated, add the technician’s working space around it, then read the result inside the range. Send both figures together — part width and space available on site — because the second governs what can be built.

What to do next
Send the dimensions of the largest part to be coated, your site area and the supply capacity available, and we will come back with an internal size and a configuration built on it. Talk to a specialist. The published range sits on the paint booth family page.
