It is lightweight yet mechanically strong, ensuring stable operation, easy maintenance, and long-term reliability.
AAL Filter’s FRP high-flow series includes melt-blown cartridge housings, bag filter housings, high-flow cartridge housings, and multi-stage FRP filtration systems—offering complete compatibility across various flow rates, processes, and installation requirements. The housing is fully compatible with Parker, 3M, Pall, and other major high-flow cartridge brands, providing users greater supply flexibility and cost efficiency.
Manufactured using advanced fiberglass winding, the vessel offers:
● excellent corrosion resistance
● high mechanical and pressure strength
● long-term structural stability
Perfect for seawater desalination, chemical processing, and corrosive industrial applications.
Supports 2–12 pieces of 40" Parker high-flow cartridges, enabling:
● high throughput
● extended filtration cycles
● greater dirt-holding capacity
Ideal for large-scale industrial filtration lines.
The top sealing chamber includes an adjustable sealing block and high-strength compression nut, ensuring:
● secure cartridge installation
● zero-bypass sealing
● stable filtration performance
The ergonomic lifting ring allows operators to open and close the housing easily, reducing downtime and improving service efficiency.
Available sizes: DN100, DN125, DN150, DN200, DN250
Connection options include flanged, clamp, or customized types.
The eco-friendly coating improves surface durability, corrosion resistance, and aesthetics. Custom colors are available for factory integration or branding needs.

1. Ensure the filter cartridge is installed correctly and tighten the sealing block nut.
2. Do not exceed the rated working pressure (≤ 6 kg/cm²).
3. Before system startup, open the air-release valve and close it after all air is expelled.
4. If the inlet–outlet pressure difference exceeds 1.5 kg/cm², replace the cartridge immediately.
The housing is widely used in industries requiring high flow, high corrosion resistance, and long service cycles, including:
● Seawater desalination & pretreatment
