Nuaire FumeGard NU-164 By-Pass Fume Hood

A Safe Continuous Environment
Constructed of stress-relieved polypropylene, the FumeGard NU-164 has a by-pass (protected by a grill) that maintains a constant volume of airflow. As the sash is closed, air is by-passed at the top of the hood, causing the hood face velocity to increase much more slowly than a conventional fume hood. A deflector vane across the bottom of the opening directs airflow across the work surface. This provides a permanent opening even when the sash is closed. Most of the exhausted air enters the fume hood through the by-pass. The eye-level Control Center has on/off switches for exterior mounted fluorescent light or optional electrical devices (outlets, window alarms, night setback controls, or exhaust blower interlock systems).
