SFN series filters represent versatile equipment used to perform various aspiration tasks in a wide range of processes. These are cost-effective, fully automatic self-cleaning modular continuous pocket filters with compressed-air pulse regeneration. Pockets are installed in one section horizontally, 12 pieces in a row, from 1 to 7 rows up. Filtration surface area of one module ranges from 18 to 126 m2. The filter is designed for continuous operation to clean air or gases from various types of dry loose, fibrous, and slightly sticky dust, with an input concentration of up to 50 g/m3. The SFN filter is suitable for indoor and outdoor installations. Its modular design allows achieving the required capacity by choosing the size and number of sections. For dust discharge, the series uses containers for dust collection (drums of 60 and 100 l), equipped with manual cut-off valves to block the dust discharge point when the drum is removed from the running filter.
Applications
• Aspiration of furnaces, cast houses
• Aspiration of silo and bunker loading/unloading
• Aspiration of process and associated equipment
