Product Categories / Laminar Flow Hoods

The DFMZ LHV Series Vertical Laminar Flow Hoods create the ideal environment for processes that require excellent product protection. The downward vertical airflow blankets the work surface with HEPA-filtered clean air (ISO 5 conditions) while maintaining positive pressure within the work zone. The all welded polypropylene construction of the LHV Series Hoods offer excellent resistance to many acids and other chemicals as well as being suitable for metal-free and low level trace analysis applications.
