Horizontal Laminar Air Flow Unit

Horizontal laminar flow hoods direct air, well, horizontally. Air is pushed through a HEPA or ULPA filter positioned on the back wall and moves forward across the work surface until it exits the enclosure.Laminar flow hoods are available in horizontal or vertical airflow configurations. A horizontal flow hood will move air from the back of the unit through HEPA or ULPA filters and to the front of the work surface. A vertical flow hood will move air from the top of the unit through filters and down to the work surface.Fan or blower sucks the prefiltered air from the filter pad that primarily traps the air contaminants. Then, the prefiltered air goes through the high-efficiency particulate air filter that removes the contaminants like fungal spores, bacteria, dust etc.
