The AAL Angle-Type Self-Cleaning Filter is a high-efficiency automatic pipeline filtration system specially designed for industrial water treatment and process water applications. Featuring a compact vertical cylindrical structure, the filter is mounted directly onto the pipeline, allowing efficient space utilization and simplified system integration.
Compared with traditional filtration equipment, the Angle-Type Self-Cleaning Filter offers a more compact footprint, making it particularly suitable for installations with limited space. Its intelligent automatic cleaning mechanism continuously removes accumulated contaminants from the filter screen without interrupting system operation, helping reduce maintenance frequency and minimize downtime.
Designed for reliable long-term operation, the AAL Angle-Type Self-Cleaning Filter combines high filtration efficiency, flexible maintenance, and convenient disassembly. It is widely used in industrial pipeline filtration, cooling water systems, process water treatment, wastewater filtration, and UF/RO membrane pretreatment applications.
The vertical angle-type design allows direct installation onto industrial pipelines while minimizing installation space requirements, making it ideal for compact filtration systems and retrofit projects.
The filter automatically initiates the cleaning cycle based on differential pressure or preset timer settings, reducing manual maintenance and ensuring continuous industrial filtration.
Equipped with a high-strength stainless steel filter screen, the system effectively removes suspended solids and protects downstream equipment such as pumps, heat exchangers, nozzles, and membrane systems.
The optimized structure allows convenient maintenance and flexible disassembly, helping reduce servicing time and operational costs.
During the cleaning cycle, the filtration process continues without shutting down the system, ensuring stable operation in continuous industrial processes.
The optimized self-cleaning mechanism minimizes backwash water usage, helping reduce overall water consumption and operating costs.
The filter is engineered to handle high flow rates and elevated suspended solids content, making it suitable for demanding industrial water filtration systems.
