Frequently Asked Questions

When should I use a downdraft table rather than a fume extractor with an arm?

It can be beneficial to use a downdraft table when perfoming applications like sanding, welding, and grinding. Extact-All Downdraft Tables will draw contaminants (i.e. dust, fumes, smoke) down and away from the operator’s breathing zone.

Can I use my downdraft table for painting?

Downdraft tables can be used to capture fumes from light touch-up painting. However, downdraft tables are not meant to capture or filter paint and may cause damage to the filters or unit.
