Downflow Unit

TopAir’s Downflow Workstation is a standalone, ductless unit that protects lab staff from harmful powders or fumes.

The Downflow Workstation features an open structure which enables close inspection of various lab materials, and still provides a high level of protection.

Particles or fumes flow downward through the stainless steel work surface and contaminants are removed using several filters.

Following the filtering of fumes or particulates, clean air flows back into the room.
