These often very fine, respirable dusts are a strain for humans and the environment and must be retained inside the processing system. Silo vent filters are used for these applications because they assure the best separation efficiency. Infastaub, the German manufacturer for dedusting solutions, has turned its attention to these needs. The size of silo vent filters will depend on the bulk characteristics and process parameters. Often plant operators or plant contractors choose filters that are too small or inappropriate, causing defects in production. The costs of a correct lay-out are negligible if you consider the avoided costs of by shutdowns, retrofits or rebuilding caused by filter malfunction.
