Superior finish quality
Vertical airflow removes overspray quickly and evenly, reducing contamination and delivering consistent results.
A downdraught spraybooth is designed to deliver clean, controlled airflow from ceiling to floor, drawing overspray and contaminants away from the painted surface.
Air is introduced evenly through the roof plenum and extracted at floor level, creating a stable, vertical airflow pattern that supports consistent, high-quality finishes. This configuration is widely recognised as the benchmark for paint application in professional bodyshops.
At STL, we don’t take a one-size-fits-all approach.
Our team works closely with each customer to assess workflow, throughput, available space and site constraints before recommending the most suitable airflow solution, whether that’s downdraught, rear extraction, side extraction or a hybrid configuration. The result is a spraybooth layout that delivers the right balance of finish quality, efficiency and practicality for your operation.
Downdraught airflow is proven to deliver superior finish quality, cleaner working environments and efficient booth performance.
Vertical airflow removes overspray quickly and evenly, reducing contamination and delivering consistent results.
Contaminants are drawn away from the vehicle and operator, improving visibility, safety and working conditions.
Even air distribution across the entire cabin supports repeatable performance across every job.
Widely adopted across professional bodyshops for its reliability, quality and performance.
The Cyclone is a high-performance downdraught spraybooth designed for busy, high-throughput bodyshops. With true wall-to-wall inlet filtration and flexible floor extraction options, it delivers uniform airflow and consistent finishing quality. As with all STL spraybooths, the Cyclone is engineered for long-term reliability, offering a market-leading solution backed by proven performance and in-house expertise.
The STL Qube offers a self-contained, external bodyshop solution that can be configured with downdraught airflow for controlled, professional finishing. Designed to integrate preparation, spraying and curing within a single enclosed structure, the Qube delivers the benefits of downdraught performance while making efficient use of available space. It is an ideal solution for sites with limited internal workshop capacity or where expanding existing facilities is not practical.
STL systems meet leading industry standards and accreditations, giving our clients confidence in safety, compliance, reliability, and long-term performance.
