![]() ![]() Our HEPA filters are available in several different sizes and are compatible with our laminar flow hoods as well as with clean rooms and other brands of laminar flow hood. We sell a range of pre-filters and high efficiency filters. The Ossila Horizontal/Vertical Laminar Flow Hood accepts a variety of different types of filter. H14 HEPA filter - 575mm x 575mm replacement filter 99.999 Effective - Perfect solution for DIY Laminar Flow Hoods 5 out of 5 stars (226) Sale Price 287.64 287. Passing the air through a pre-filter prevents larger particulates from reaching (and subsequently clogging) your HEPA filter. To extend the useful life and efficiency of your HEPA filter, we always recommend using a laminar flow hood pre-filter. This grade of air filter can achieve air cleanliness values of ISO Class 5, giving you a working environment with a minimal amount of particulate contamination. Our HEPA filters are H13 grade and will capture up to 99.99% of particulates from the air passed through them by the laminar flow hood. High Efficiency Particulate Air (HEPA) filters use a pleated microfibre structure to capture particles across a wide range of size. HEPA filter and laminar flow products are manufactured in Australia under an accredited Total Quality Management system.Clean rooms and laminar flow hoods use filters to capture airborne particles to keep the air in the room/hood clean and particle free. Holding frames that provide effective clamping and sealing of filters are available for ducted applications. These modules are suitable for use in ceilings of plasterboard or laminated-panel construction, and can be supplied in fan-assisted configuration. TFP modules are terminal HEPA filter plenums fitted with Microseal™ filters, and are designed for ceiling installation in new cleanroom construction, or for upgrading existing rooms. In typical laminar flow systems, filters have an initial resistance of 120-130 Pa, and are replaced if non-uniform airflow characteristics are observed or when increased resistance due to dust loading affects airflows. However, in most ventilation applications, filters are selected to operate at much lower pressures, and are replaced when dictated by system fan performance, or at a specified final resistance. ‘Type’ testing has shown that Microseal™ filters can safely withstand static pressures up to 2.5 kPa. Fluid seal filters are suitable for use up to 55✬. Standard filters are suitable for conditions up to 115✬ and 100% RH. Find products of Tool Parts with high quality at AliExpress. All testing is conducted in a ISO-registered factory laboratory, and a ISO-endorsed test label, being an extract of the test report, is affixed to each filter. Buy laminar air flow replacement dust hepa filter with free shipping and free return online. Their light weight and compact dimensions make them the preferred selection for laminar flow cleanrooms and low-profile ceiling modules.Įach filter is individually certified to achieve an arrestance efficiency of not less than 99.995% to the stringent BS3928 Sodium Flame test. Typically, a minipleat filter has similar airflow/pressure drop characteristics to a conventional filter of the same face dimensions, but has only one third of the depth of the conventional filter. These filters are of low-depth construction and use very close pleating of the medium, with separation of the pleats achieved by means of continuous, narrow beads of a special hot-melt compound. Filters are produced in a wide range of face dimensions and in two standard depths of nominally 150mm and 300mm. The rated filter life is 3,000 hours or 3-5 years of normal use. Standard filters have a closed-cell neoprene gasket on the air-leaving side, and filters for fluid seal installation have an extended frame with a 60mm skirt to engage the sealant channel. Bonsai HEPAFLOW-12 & Bonsai HEPAFLOW-XL Replacement HEPA Filters. Filters for trace-metal laboratories are produced in ‘metal-free’ construction with wood frames and non-metallic separators. This forms the filter element which is bonded into a rigid corrosion-resistant steel frame with all joints encapsulated and sealed in a special urethane elastomer. A laminar flow hood, also called a clean bench, is a piece of laboratory equipment used to prevent workspace contamination. A continuous sheet of special microfine glass-fibre filter medium is pleated into a vee configuration with corrugated aluminium separators inserted between the pleats. ![]()
