Vertical laminar flow Class II B2

MAS Laminar flow hoods are designed to protect samples and parts from particulate contamination. Air flows in a uniform direction with a constant speed within the enclosed bench with little to no crossover air streams. Airborne contamination is filtered through HEPA (filter 99.99% @ 0.3µm) or ULPA (99.999% @0.12µm) filters providing the cleanest work area. 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. Things to consider before purchasing a flow hood is the direction the air should flow, operator safety, clearance requirements, work surface required. Fans and filters are positioned at the top of a vertical configuration hood. Particles not captured by the filters are pushed out through front access area of the unit. A vertical flow helps move micro-contaminates onto the work surface or the laboratory floor, eliminating contaminants from floating around inside the enclosure. Laboratories with limited floor space may want to go with a vertical configuration. Since the fan and filters sit at the top of the unit the flow hood can be installed on a standard lab bench. Unlike a vertical flow hood, a horizontal flow configuration hood will require additional rear clearance to allow air to enter the enclosure. A deeper workbench and floor space will be required due to fan and filter placement.Class II BSC’s is a combination of Laminar flow hood and a laboratory fume hood that Provides personnel, product, and environmental protection, Biosafety Class II is to maintain the sterility of materials inside.
