What is the difference between a backdraft table and a downdraft table?

Downdraft tables and backdraft tables are both designed to capture and extract airborne contaminants during various tasks. The key difference lies in the airflow direction. In a downdraft table, air is pulled downwards through a perforated or grated surface, making it ideal for operations producing heavy particulates like sanding or grinding. On the other hand, a backdraft table directs air horizontally from the front to the back, capturing rising fumes, which makes it suitable for tasks like welding where fumes ascend. The choice between them depends on the specific nature of the work and the contaminants produced.
