Improved Allergen Protection
Dynamic Air Barrier
The single-sided design of model NU-621 creates a dynamic air barrier of 75 fpm (0.38 m/s) at the opening of the cabinet. The result is a more powerful air barrier improving allergen protection and animal sterility.

Minimize Work Zone Heat Build Up Redcuing Stress on Animals
Single Pass Airflow
The airflow pattern starts with the supply pre-filter located on top of the station, continues through the supply Impeller and through the supply HEPA filter providing 99.99% particle removal at 0.3 microns. The airflow moves in a uniform vertical pattern providing particulate-free air in the work zone. The down flow air is then pulled into the vacuum slots around the work surface, through the exhaust pre-filters, and the exhaust HEPA filter.

Making Transfers Easy
Large Access Opening
A Large 14-inch (356 mm) Access Opening makes it easy to add and remove the largest cages while providing your arms an extended range of motion.

Spacious Work Zone
