Weighing Booth Extractor

Weighing Booth Extractor is designed specifically for powder containment applications, the Powder weighing enclosure employs carefully directed inward airflow at the face of the enclosure to hazardous powders or potent pharmaceutical compounds. The aerodynamically designed enclosure reduces airflow turbulence for maximum containment while minimizing the effect that air drafts may have on sensitive weighing balances. The enclosure design exceeds the containment requirements of proven by independent type testing. All exhaust air is HEPA-filtered, removing virtually all particulate matter, before recirculation to the laboratory.

weighing booth extractor Unitis with a variety of standard dimensions also our cabinet can be custom engineered to any size. Weighing Booth Extractor available in powder coated Mild Steel, SS 304 / 316 / 316L or a combination of both.
