The FA series self-cleaning safety filters can be installed on lines designed to transfer fluid products (chocolate, cream, fatty substances, etc.) to the final processing stage in order to remove any unwanted foreign bodies. The product transits through the system, featuring a rotary filtering basket, equipped with a scraper for removing the impurities that are discharged through a special valve. The filters are fitted with a sleeve for the circulation of tempered water and can also be added to existing lines, even in very limited spaces.
