Purair vertical-flow cabinets guide a laminar flow of air directly toward the work surface. An ultra-low-penetration air (ULPA) filter is mounted above the work surface, and perforations in the rear wall remove a small amount of air to minimize turbulence. The cabinets are available in 36-in., 48-in. and 72-in. widths. All three models provide a nominal filter face velocity of 0–45 m/s (90 ft/min), which ensures a sufficient number of air changes for maintaining cleanliness within the work zone.
