5 inches and 10 inches PRI Series-Integrated Saccular Filter Cartridge used for slurry filtration

PRI Series For New Energy Field

The PRI series filter cartridge features a unique saccular structure. The feed liquid does not come into contact with the external environment, reducing harm to operation personnel. After replacing the filter cartridge, there's no need to clean the filtration device, which improves the operation environment while shortening replacement time and reducing labor costs.The tight structure of the internal winding filter cartridge and the saccular enclosure significantly reduces slurry loss.

The internal filter cartridge uses a winding style gradient filtration, layer‑by‑layer interception of particles of different sizes,effectively utilizing the multi‑layer gradient structure to increase the filter cartridge's dirt holding capacity, thereby prolonging the filter cartridge's use lifespan.

Each filter cartridge undergoes 100% pressure testing before leaving the factory to assure product quality and safety.

Application:

PRI filter cartridges are widely applied in the slurry coating process of lithium-ion battery manufacturing and have been used in production lines serving leading battery manufacturers, including CATL, Sunwoda, Samsung Battery and other major players in the new energy industry.

In cathode and anode slurry preparation, PRI filter cartridges effectively remove agglomerates, gel particles and process contaminants, ensuring stable slurry quality before coating. Reliable filtration performance helps improve coating uniformity, reduce defect rates and protect precision coating equipment from blockage or abnormal wear.

With stable structure, consistent pore size distribution and excellent chemical compatibility with battery slurry systems, PRI filter cartridges support continuous operation under high solid content conditions. They have been proven suitable for large-scale, high-efficiency battery production environments, contributing to higher yield, process stability and consistent battery performance.
