SFFILTECH’s DFM/DFG scraper self cleaning filter housing is designed for continuous, high efficiency filtration of liquids with high solid content or viscosity. The internal scraper mechanism automatically removes contaminants from the filter element without interrupting flow, ensuring stable pressure and long service life.

Key Features

• Scraper self cleaning mechanism enables continuous operation with minimal downtime.
• Handles low to high viscosity fluids with filtration precision from 50 μm to 500 μm.
• Robust construction using stainless steel (304/316L) or carbon steel to withstand high temperatures and pressures.
• Automatic or manual scraping options to suit your process requirements.
• Easy maintenance with quick element replacement and reduced labor costs.
• Compact footprint and customizable inlet/outlet orientations for simple integration into existing systems.

Typical Applications

• Cooling water and process water filtration in chemical and petrochemical plants.
• High viscosity fluids such as adhesives, resins, paints, inks and polymers.
• Food & beverage industry, including sugar refining, starch production and vegetable oil filtration.

Why Choose SFFILTECH

FAQ

Q: What materials are used in SFFILTECH filter housings?
A: Our filter housings are built from high-quality stainless steel (304/316L) or carbon steel to resist corrosion and ensure long service life.

Q: How does a scraper self-cleaning filter housing differ from a cartridge filter housing?
A: A scraper self-cleaning filter housing uses an internal scraper mechanism to continuously remove contaminants without interrupting flow. Cartridge filter housings use replaceable cartridges that trap particles; they require periodic replacement rather than automated cleaning.

Q: What are the benefits of stainless steel filter housings?
A: Stainless steel filter housings offer superior strength, high temperature and pressure resistance, and sanitary surfaces suitable for food, beverage and pharmaceutical applications. They are easy to clean and maintain.

Q: When should I choose a scraper self-cleaning filter housing?
A: Scraper self-cleaning filter housings are ideal for processes involving high-viscosity fluids or liquids with heavy solids loading where continuous filtration and minimal maintenance are important.
