AAL PSM Pleated Stainless Steel Mesh Melt Filter Cartridge: Durable, Reusable Filtration for High-Temperature Melt and Viscous Fluid Applications

Product Overview

The AAL PSM Pleated Stainless Steel Mesh Melt Filter Cartridge is engineered with woven stainless steel mesh as its primary filter media, utilizing a precision pleated structure to significantly enhance filtration surface area and flow efficiency. Renowned for its exceptional temperature and pressure resistance, this cartridge excels in precision filtration for demanding conditions involving molten materials, high-temperature liquids, and corrosive media.

What Are Metal Filter Cartridges?

Metal filter cartridges are designed for challenging applications where conventional filter media fall short, such as high temperatures, high pressures, corrosive chemical media, or scenarios requiring frequent cleaning and reuse. Typically crafted from 316L or 304 stainless steel, they can also incorporate titanium alloys for enhanced corrosion resistance and strength in extreme environments.

AAL Filter’s Metal Series

AAL Filter’s AAL PSM metal cartridge series is specifically developed for high-temperature, high-pressure, and high-viscosity molten media filtration needs. Featuring multi-layered woven stainless steel mesh as the core filter media, combined with precision pleating and full-welded construction, the AAL PSM delivers a robust, corrosion-resistant cartridge with an expansive filtration surface area.

Through optimized pleated design, the AAL PSM maximizes filtration efficiency while maintaining a compact form factor, making it ideal for high-viscosity fluids and precision filtration applications. Its all-stainless steel construction ensures outstanding high-temperature performance and mechanical strength, supporting multiple regeneration methods like backwashing, ultrasonic, and chemical cleaning. This reusability reduces operating costs and extends equipment lifecycle, positioning AAL PSM as a trusted industrial filtration solution for rigorous conditions.

What Is the AAL PSM Pleated Stainless Steel Mesh Melt Cartridge?

The AAL PSM metal cartridge employs multi-layered woven stainless steel mesh as its primary filter media, formed through precision pleating to create a large filtration surface area and stable flow path. Its typical structure comprises inner and outer support meshes, a primary filtration layer, and a protective layer, sealed with argon arc welding for superior structural integrity and leak-proof performance.

With uniform pore distribution, exceptional high-temperature and high-pressure resistance, and excellent cleanability, the AAL PSM is optimized for efficient filtration of high-temperature molten materials, viscous liquids, or particle-laden chemical media. Its all-metal construction ensures long-term stability in complex conditions, meeting the stringent demands of industrial filtration for strength, efficiency, and reusability.
