A multiple-stage HEPA filter and pre-filter can be developed to ensure the laminar hood is filtering air particles efficiently and keeping Contact APC for Custom HEPA Filters for Laminar HoodsĪPC Filtration has been designing, testing, and manufacturing custom HEPA filters for laminar flow cabinet hoods. Often, laminar hoods will require custom HEPA filters to be created to ensure they create the right pressure drop and fit the equipment perfectly to prevent leaks. Air is taken through this HEPA filtration system and exhausted across the work surface as part of the laminar flow process.īecause a laminar flow cabinet is enclosed on the sides, a constant positive air pressure can be maintained to prevent the intrusion of contaminated room air and personnel contamination. This set up id designed to create a particle-free working environment and provide product protection from contamination. Laminar flow hoods create this unidirectional flow of air with one or more HEPA filters and pre-filters. Class III biosafety cabinets provide the highest attainable level of protection to personnel and the environment and are suitable for human pathogens and BSL-4 materials.
Class II are designed for work involving BSL-1, 2, and 3 materials and provide an aseptic environment for cell culture experiments. Class I is suitable for laboratory personnel with similar air flow characteristics to chemical fume hoods. Each of these are suitable for working with different types of materials as each has its own level of protection and filtration. There are three classes of laminar flow hoods, Class I, II, and III. The flow can either be horizontal or vertical, depending on the lab’s needs. Laminar flow hoods work to protect the working environment from dust and other airborne contaminants by maintaining a consistent, constant, unidirectional flow of filtered air over the work area.
