Fully Automated Internal Scraper Self-Cleaning Filter

The internal scraper self-cleaning filter is an efficient, automated filtration device that employs an internal scraping mechanism to automatically remove impurities from the filter screen during the filtration process. Through its automated self-cleaning function, it effectively enhances filtration efficiency, reduces maintenance costs, and ensures continuous and stable operation of the system. It is widely used in petrochemical, fine chemical, pharmaceutical, power, papermaking, water treatment systems, automotive industry, mechanical processing, coatings, electronics, and other industries.
