Aviation coatings require precise environmental control over temperature and humidity in order to cure properly, and contamination control is a vital factor in the aviation finishing process. GFS aircraft paint booths meets and exceeds the highest standards in the world.
GFS has designed aircraft paint booths with both downdraft and crossdraft airflow. Air flows through each booth differently, and each style has its own advantages.
Generally regarded as the best airflow style, downdraft aircraft paint booths are a sign of a truly world class finish. There’s an advantage of allowing gravity to pull overspray to a pit in the floor. Downdraft aircraft booths can be designed for a specific plane to optimize the airflow design and overall efficiency. For the most economical design, a downdraft booth should be incorporated early into your facility’s design process.
Making up about 75% of all aircraft paint booths, crossdraft booths are the most common style of booth for aerospace finishing operations. Air flows from end to end in a crossdraft booth, matching the natural flow of air across the aircraft. This provides excellent quality finishes.
Aircraft paint booths can be constructed within an existing hanger or as an integrated part of new building construction.
If hanger space is available, Aircraft Paint Booth Inserts may be the perfect solution for your refinishing operations. Paint booth inserts are placed inside the hanger and are completely self-supporting, requiring only that the user bring in utilities and connect to the insert. GFS' aircraft paint booth inserts are typically purpose built for the type of aircraft being painting in the facility.
In some instances, such as new building construction, it is better to integrate the paint booth with the building elements. With a Hybrid Aircraft Paint Booth, the structure of the hanger holds up the booth ceiling and the building sidewalls can be integrated into the booth design to economize on material. GFS will work with the building architect(s) to integrate our paint booth design goals with the building design goals.
Aerospace National Emission Standards for Hazardous Air Pollutants (NESHAP) requires the use of high efficiency filters to remove 95% of particles over 2 micron in size under certain conditions. The use of a 3-stage filtration system is mandatory and the filters must be in accordance with EPA Method 319. GFS uses a filtration system that provides 99% removal of most paint spray aerosols. This exceeds the requirements of both of these environmental protection agencies. The 3-stage filtration system consists of roll media, a MEPT panel filter and a 6-pocket bag filter.
As with all of our booths, GFS' aircraft paint booths feature superior lighting. Ceiling and wall lights are strategically placed to provide a luminous environment for the painter to apply the finishing touches. GFS will work with you to design the most energy-efficient lighting setup for your paint booth, without sacrificing quality.
Low-energy consumers, T-8 fluorescent fixtures are used in the majority of our paint booths designs. Some booths, especially larger ones, utilize T5-HO tubes. T5-HO lights give off much more light than a plain T-5 light. Although they use more power than T-8 lights, less fixtures are needed because they give off more light. For high-bay facilities above 35 ft., HID lights are used.
Plenum Filter Doors
Plenum Filter Doors allow for fully controlled airflow into the booth. They are only used on crossdraft booths that are forced draft booths. The air is double or triple filtered to provide the ultimate in cleanliness and freedom from dust and lint. The only way that dirt can enter the booth is for painters to carry it in.
The use of an air-ride suspension on the door drive system is unique and provides the most forgiving ride for this style of door over uneven terrain. The design keeps a low center of gravity to allow for precise control of the door positioning and low inertial wobble. It also provides a wide steady base to resist.
Doors are a critical element of paint booth design and many options are available to suit the layout of an installation. These include:
GFS guarantees that our products meet or exceed all of the applicable codes related to the equipment. Our engineers regularly follow and contribute to the advancement of codes and standards that affect the industries that we work in. One of our engineers currently serves on the NFPA Technical Committee on Finishing Processes, a key standard in the finishing industry.
GFS has pioneered the use of conformal aircraft paint booths. With this design, air is introduced at a higher velocity in the spraying zone than in the non-spraying areas of the paint booth. This provides excellent painting performance, while minimizing the amount of air and energy required for the process.
In some cases, these designs can result in a savings of 15-30% in capital and operating costs when compared to that of a traditional booth design.
With computational fluid flow dynamics (CFD) software, our engineers can simulate booth airflow performance. This technology is especially beneficial for large, custom projects, as it allows us to test our engineering designs before the equipment is built, saving time and money, and improving the overall product performance.

Modern aircraft paints are best applied in a narrow temperature range. To help maintain the required temperature and humidity in the paint booth, temperature and humidity controls can be designed into the air replacement systems.
GFS has successfully integrated these controls into many of our aircraft paint booths.
Recirculation is an effective method of reducing not only operating costs of the paint booth, but also equipment costs.
GFS can provide a recirculated air system for your booth that will provide accurate control of the booth climate and airflow, while providing the most efficient operating system possible.
