Aircraft paint booths must be designed to fit the aircraft's unique shape and size in order to reduce artist exposure to process hazards, reduce energy costs, improve coating quality and increase production. The biggest factor in achieving this is ensuring airflow is where it is most needed – on the surface of the aircraft.
The two most common airflow forces for aircraft paint booths are crossdraft and downdraft. Both types of airflow have advantages and disadvantages. You can also visit https://spraytech.com/aerospace-refinishing/aircraft-paint-booths/ to know about aircraft paint booth manufacturers in CA.
Here are some considerations when choosing between cross flow and downflow for an airplane paint booth:
1. Type of aircraft
The crossdraft spray booth offers the greatest flexibility and configuration options to handle a wide variety of aircraft types and sizes in one chamber. Smaller cabin aircraft for large aircraft can also be placed closer to the exhaust system to optimize airflow around the aircraft.
Although downdraft spray chambers lack flexibility in accommodating different aircraft sizes, they are very effective in handling a single airplane model or multiple models with similar wing and fuselage profiles.
2. Control over spillage
Controlling excess spray during the painting process is very important not only for the quality of your finished product, but also plays an important role in ensuring the painter's safety and process efficiency.
3. Easy to change filter
Replacing the filter in an aircraft paint booth can be time consuming and expensive, as most aircraft cabins require exhaust gas filtration that meets three-stage NESHAP standards.
4. Paint quality
Undoubtedly, the paint booth provides a more efficient environment for painting aircraft, resulting in a better paint job compared to an open paint hangar.
