1) All downflow containment booths feature Class 100 (ISO 14644-1 Class 5) HEPA filtered air at 90-100 fpm over the entire ceiling, resulting in no updrafts that would contaminate pure raw materials and endanger workers' safety.

2) Pre-filter intakes at low levels provide Class 100 air over small drums as well as large containers.

3) Negative pressure in the booth prevents material from escaping to the outside.

4) Smooth cavity-free containment walls allow for easy wipe down.

5) All models are covered by a three-year warranty.

6) All products are designed for long-term use and are of the highest quality construction.
