The Defender Series of Industrial Downdraft Tables by Clean Air Industries is your ultimate source capture solution for weld and soldering fume, grinding dust, and more. Defender Downdraft Tables boast a flexible modular design, available in standard sizes of 4×3, 4×6, and 4×9, ensuring an even face velocity and exceptional airflow ranging between 4,200 – 9,000 CFM.

Engineered to exceed typical industry standards, Defender Downdraft Tables prioritize safety and tranquility in your workspace. They feature an integrated exhaust silencer to minimize noise and advanced spark arrest technology to maximize safety.

Our exclusive quick-release doors make filter rotation or replacement a breeze. The built-in filter cleaning system efficiently dislodges dust, directing it into an accessible dust drawer for quick and easy maintenance.

You can customize your Defender Downdraft Table to meet your operational needs, with options including blue cushion protective matting, HEPA afterfilters, durable metal or clear Lexan back walls, side walls, and dividers, and more.

Health and Safety

Health and safety issues are being taken very seriously by a growing number of companies as OSHA, International, and industry standards increase. Many large US manufacturers are adopting European exposure limits as a global standard for their entire company and are exceeding OSHA Standards.

To meet these standards companies must implement a highly efficient dust and fume filtration system to filter out the harmful particulate. 

The European exposure limits these companies are targeting range from .02 – 1 mg/m3 depending on company policy, well below the 5 mg/m3 standard set by OSHA.
