A Negative Flow Exhaust Workstation is the only option when you don't have access to ductwork.

Negative flow exhaust filtered workstations are used primarily in laboratories all across the world. It is a very fine tuned system of internal vents and ducts. The purpose of a negative flow exhaust workstation is to eliminate the need to duct to the outside of the room. Some times it is the only way to solve an air or fume issue. The air actually passes through 3 separate HEPA vent chambers. Each filter then filters the exhaust content to .03 microns of contaminants. Cleanzones' negative flow exhaust workstation also comes with a lighting system and a air speed adjust control. You can adjust the air flow from 70 - 180 fpm.
