A wide range of filters for any level of filtration and contamination is available for the scraping cleaning system. Laser filters are used for fine filtration (from 60 mm to 300 mm) and punched filters for coarse filtration (up to 2000 mm). The working life of a punched filter can reach 1 week, while a laser filter can last up to 2 weeks. Laser and punched filters can be cleansed in a pyrolytic oven and reused up to 4 times for cutting cost. Back-flushing cleaning system is suitable for slightly contaminated materials and economic metallic mesh filters can be used.
