Helicopter Paint Booth: The Rotor Governs Width, Not Length

Helicopter Paint Booth

Planning a chamber for a rotorcraft with fixed-wing habits gets the governing number wrong. An aeroplane drives length first; a helicopter drives width and height, because the rotor reaches out horizontally and the fuselage sits tall.

A helicopter paint booth is designed around that difference, and the final size comes from your structure rather than from a category.

Width before length

The delivered range in this family extends to 24,000 mm long, 20,000 mm wide and 6000 mm high — a range that takes structures at this scale. But where you sit inside it is set by required width first in this case.

The first practical question is whether the airframe enters with the rotor fitted or removed. The answer changes required width fundamentally, and it is an operating decision settled before design rather than after.

The door follows the widest section

The main door on large builds reaches 14,200×5,000 mm under powered operation, because an opening that size is not hand-operated on a repeated cycle.

It is measured on the widest section that actually enters, not on the airframe’s datasheet dimensions. That item specifically is discovered late on most projects that end up needing a redesign.

Airflow and safety at volume

Air capacity follows the volume rather than the aircraft type, with a published range reaching 190,000 m³/h per supply or extraction set. Large-structure builds also carry three-stage bag and high-efficiency filtration at ≥98%, plus gas monitoring and static discharge.

Preparation and painting are two stages

Stripping, preparation and inspection precede painting, and each carries different extraction requirements. Combining them in one volume makes one run short, and we fix the number of chambers after reviewing your process.

Frequently asked questions

Have you delivered a chamber for a rotorcraft specifically?

Our published delivery range covers chambers to 24,000 mm long, 20,000 mm wide and 6000 mm high — airframe dimensions rather than vehicle dimensions. Reference projects that can be named publicly are requested from the sales team directly.

How does it differ from a fixed-wing chamber?

In how the dimensions distribute, not in principle. An aeroplane drives length and a rotorcraft drives width and height, and both sit inside the same published range. We take your airframe dimensions and build on them.

Can humidity be held in this chamber?

Yes where the coating or the acceptance requirements call for it. Temperature and humidity control together is delivered on custom builds, with the range set per project from the finishing material and the part’s requirements.

How many chambers does the project need?

It depends on stage separation. Stripping, preparation and inspection need different extraction from spraying, and combining them shortchanges one. We fix the number after reviewing your line.
