This page covers vent-filter and dust-aspiration installation arrangements: direct silo mounting, floor-mounted units with hoppers, and aspiration at powder transfer or dump-hopper points. Filter area, cleaning method, fan arrangement and materials are selected for the dust and process duty. For the Tuff-Vent® product range and standard options, see the Tuff-Vent® silo vent filter page. Particulate filters do not treat every gas or vapour; the required treatment scope must be assessed separately.
