Purifier Class I Enclosures protect the user from agents that require Biosafety Level 1, 2 or 3 containment but no product protection.

Exclusive features include an ergonomic air foil with aerodynamic Clean-Sweep airflow openings, upper dilution air supply and zone-perforated rear baffle with side-entry air foils and upper containment sash foil. These enclosures are designed for a nominal inflow velocity of 75 to 105 fpm. They are calibrated for use with 99.99% efficient exhaust HEPA filters. Includes a built-in variable speed blower with vibration-isolated impeller. These class I enclosures are built with an intrinsically-safe, negative pressure design. Available with fluorescent and 254 nm UV lamps, a UV protection panel is interlinked. The ergonomic 10° angled and hinged sash pivots upward, locks to a loading height of 20" and has side wiping seals to contain contaminants. Also includes two utility ports. Particulate containment tested.
