Static filters in the energy and biomass industry

During the processing of biomass, dust is removed from large storage halls by means of recirculation and ventilation systems. A static filter ensures that air and dust are then separated from each other. The dust ends up in the filter and, depending on the type of filter, is either periodically replaced or blown clean using compressed air. Air Solutions Holland offers solutions that are mounted in the biomass processing rooms themselves, in an air duct or a filter plenum. The most important variables are accessibility, dimensions, filter class, filter frame and the housing / cladding. A static filter can be constructed with several different filter steps in a row. The best choice often depends on several factors: where dust is released, which substances/vapours need to be captured and how much space is available.

Air Solutions filters are available in various designs and classes from panel filters to bag filters to HEPA absolute filters or activated carbon filter cylinders to remove odour components. Filter frames are available in cardboard, plastic, galvanised steel, steel coated or stainless steel (AISI 304 and AISI 316L). The filters can then be mounted in a filter frame, filter box (single wall or insulated), air handling unit or mobile unit. Different materials can also be used for the casing. In order to be able to easily maintain/replace the filters, the cabinets are fitted with an access hatch or door.
