The AAL H Type Disc Filter is a high-efficiency water filtration solution designed for agricultural irrigation systems, industrial water treatment, and reverse osmosis (RO) pre-filtration applications. Featuring a dual disc filtration structure, this filter provides higher flow capacity and reliable filtration performance, making it ideal for continuous water filtration in irrigation and industrial systems.
Manufactured from high-strength composite engineering plastics, the filter housing offers excellent pressure resistance, impact strength, and corrosion resistance, ensuring long-term durability under demanding water conditions and outdoor environments. Combined with precision disc filter elements, the system effectively removes sand, suspended solids, and particulate impurities from water.
In RO pre-treatment and desalination filtration systems, the AAL H Type Disc Filter plays an important role in protecting downstream equipment and RO membranes. By reducing particulate contamination and membrane fouling, the system improves operational stability and extends membrane service life.
Developed by AAL Filter, a professional manufacturer of industrial filtration equipment, this disc filtration system provides a reliable, efficient, and easy-to-maintain solution for modern irrigation and water treatment systems.
The H-type design integrates two disc filtration units in parallel, providing higher flow capacity and improved filtration efficiency for irrigation and industrial water systems.
Constructed from premium composite engineering plastics, the filter housing offers excellent pressure resistance, corrosion resistance, and impact durability.
The disc filter element features precision grooves that create multiple filtration channels, effectively capturing sand particles, suspended solids, and fine particulate impurities.
The modular design allows flexible configuration and easy integration into different irrigation and industrial filtration systems.
The user-friendly structure allows quick filter cleaning and maintenance, minimizing downtime and reducing overall operating costs.
