![]() Purchase HEPA/ULPA replacement filters directly through Filtco Filters or find a range of replacement carbon filters designed to fit most global manufacturers’ models. This gauge accurately measures airflow pressure through the filter and minimizes the potential for insufficient filtration.įind more information on Purair laminar flow cabinets, applications and uses. Problem: Inability to properly monitor filter’s current particulate density causes improper filter replacement timingĪir Science’s Solution: All Air Science laminar flow cabinets have a factory-installed pressure gauge to confirm filter performance. Problem: Insufficient air flow through the filter results in limited air filtration capabilitiesĪir Science’s Solution: Purair Laminar Flow Cabinets maintain a 70-90 fpm (0.35-0.45 m/s) airflow velocity, measured 6″/150 mm from the filter with a uniformity of +/- 20% across the filter face. Using pre-filters extends HEPA/ULPA filter life and maintains filter efficiency. Pre-filters are easy to replace even while the cabinet is operating. ![]() Problem: Costly HEPA/ULPA filters become too quickly obstructed by large particulates and require frequent replacementĪir Science’s Solution: Each Air Science laminar flow cabinet includes an electrostatic pre-filter for trapping larger particulates that can accelerate the saturation of HEPA/ULPA filters. ![]() How Do Air Science’s Vertical and Horizontal Laminar Flow Cabinets Address These Issues? A flow hood consists of a coarse pre-filter, a blower and a very fine filter (the so called HEPA (High Efficiency Particulate Air) filter which filters particles from the air to a high degree. Inability to properly monitor current particulate density causes premature filter replacement timelines Insufficient or uneven airflow through the filter results in limited air filtration capabilities Some air filtration units present limitations including:Ĭostly HEPA/ULPA filters become too quickly obstructed by large particulates and require frequent replacement The highest quality filtration media cannot overcome a poorly designed laminar flow hood that does little to support and optimize the filter’s purpose. Laminar Flow Hoods: Addressing Challenges to HEPA/ULPA Filtration Replacement HEPA Filters for Clean Rooms and Laminar Flow Hoods H13 grade HEPA filters to capture up to 99. HEPA filters are 99.99% efficient for trapping particulates down to 0.3 μm, and ULPA filters provide 99.999% efficiency for particle sizes between 0.1 to 0.3 μm. We also offer an optional protective cover that doubles as a work surface.HEPA and ULPA filters are a standard in many industries for work that requires an environment free of biological contaminants.Ĭomprised of a dense mat of randomly-arranged fibers, both HEPA and ULPA filters work in the same way. If your order has not shipped in 14 days (you get an email or text when it does), feel free to contact our customer service department to get an update on your order. However, from time to time we get backed up and it takes longer. Generally this item ships in 14 days or less.
