Silent hood

Silent hood

The Silent Hood filter is a compact, low-noise, ready-to-install HEPA and ULPA filter diffuser used as a final filtration solution for cleanrooms. Ideal in laboratories, cleanrooms, hospitals, commercial kitchens, schools or wherever there is a strictly controlled environment.

Silent Hood is available from class H13 to H14 , with an MPPS of 99.95% to 99.995%. The media is pleated using our patented controlled media spacing (CMS™) technology for optimal airflow and best media performance. Together with intermediate hot-melt separators, this ensures uniform pleat spacing and the ability to form a rigid self-supported media pack. The media pack is permanently sealed to the filter frame of the module with a solid polyurethane sealant.

The frame is made of extruded and anodised aluminium, with the top connection spigot available in diameters of 305 mm or 250 mm depending on the model. The gasket seal is a seamless polyurethane gasket applied to the frame that eliminates the risk of air bypass.

Each filter is individually tested and certified to EN 1822 with a separate scan test protocol and serialized on the product label.
