Welcome to our dedicated guide on full downdraft spray booths. Whether you’re a seasoned industrial expert or just getting started, we’ll provide you with all the valuable insights to help you decide whether this type of spray booth is suitable for your needs.
Understanding Full Downdraft Spray Booths
A full downdraft spray booth is a fully enclosed paint booth designed to ensure clean and efficient paint applications while minimising the release of overspray into the surrounding environment.
The term ‘full downdraft’ describes the specific airflow pattern of the spray booth. In a full downdraft spray booth, air is drawn in from the ceiling and then pulled down, exiting through the lower exhaust system located in a concrete pit or raised floor basement. This downward airflow helps to direct overspray and contaminants away from the object being painted, guiding them towards the floor where they are captured and filtered.
Allows you to produce high quality, premium finishes.
Airborne particles are continuously directed downwards even when the painter is spraying from different directions.
The full downdraft design covers the entire work area, ensuring that overspray is effectively managed across the entire painting process.
Improves air quality and creates a much safer environment for the operator.
Typically designed with enough room to comfortably accommodate large vehicles and other sizable objects.
Easy to keep clean and provides excellent throughput capacity.
Ideal for the automotive and aerospace industries.
Things to Consider
When deciding on a type of booth to go for, it’s important to keep in mind all types of considerations. For example, a full downdraft booth requires more space compared to other conventional designs and will typically use more air (around 20 to 40 percent more). This means they require bigger air units, exhaust fans, filters, and more power – resulting in higher installation and operational costs.
Comparing Full Downdraft and Semi Downdraft Designs
Full downdraft spray booths draw air vertically from the ceiling to the floor, while semi downdraft booths employ a diagonal airflow. The difference lies in the intake and exhaust systems, resulting in distinct airflow patterns and levels of overspray control. The nature of the airflow in downdraft paint booths produces the fewest blemishes, with the least amount of buffing required.

What is a Semi Downdraft Spray Booth?
A semi downdraft spray booth is a specialised enclosure designed for the application of paints, coatings, and finishes. It’s a hybrid solution that combines distinctive attributes from both crossdraft and full downdraft booths. A ventilation system draws air from the upper portion of the booth and exhausts it through filters located at the rear. This configuration creates a controlled airflow pattern that directs overspray away from the operator and the object being painted.
How Does a Semi Downdraft Spray Booth Operate?
In a semi downdraft spray booth, air is introduced into the booth through a filtered intake plenum positioned at the upper section. This air is then guided diagonally across the work area, carrying overspray particles away from the operator. The air is finally exhausted through filters situated at the rear of the booth, ensuring clean air circulation.
Benefits of Using a Semi Downdraft Spray Booth
Semi downdraft spray booths offer several advantages for industrial painting processes:
Effective Overspray Control – The airflow pattern in semi downdraft booths effectively captures and contains overspray particles, reducing the risk of contamination and improving paint transfer efficiency.
Improved Air Quality and Worker Safety – By directing the airflow away from the operator, semi downdraft spray booths help maintain a clean and safe working environment, minimising exposure to harmful fumes and particulates.
Energy and Cost Savings – The airflow design of semi downdraft booths reduces the volume of air that needs to be heated or cooled, resulting in energy savings and lower operational costs. Furthermore, these booths eliminate the need for costly concrete installation and as such, are an excellent choice for those on a budget.
Improved Productivity – The efficient overspray control and improved airflow pattern contribute to faster drying times and shorter paint curing cycles, increasing overall productivity.
What Industries are they used in?
Semi downdraft spray booths are used in various industries, including:
Automotive Refinishing – These booths are ideal for automotive body shops and collision repair centres, providing a controlled environment for painting cars, trucks, and other vehicles.
Aerospace Manufacturing – Semi downdraft booths excel in achieving high quality finishes for aircraft components, including fuselages and wings, while adhering to rigorous industry standards.
Woodworking and Furniture Production – The controlled airflow in these booths enables precise application of finishes on wooden furniture, cabinets and other woodworking projects.
Industrial Coatings and Painting Processes – Semi downdraft spray booths are suitable for a wide range of industrial applications, such as metal fabrication, machinery painting, and equipment coating.
What’s the difference between Downdraft and Semi Downdraft Spray Booths?
Full downdraft spray booths draw air vertically from the ceiling to the floor, whereas semi downdraft spray booths draw air diagonally from the upper portion of the booth towards the exhaust filters. The main difference lies in the position of the air intake and exhaust systems, affecting the airflow pattern and the level of overspray control achieved.
