AALBF-4A Solid-Liquid Separation Polypropylene Filter Housing for Acid and Alkaline Filtration

The AALBF-4A PPH Filter Housing is a compact yet high-performance polypropylene bag filter housing designed specifically for solid–liquid separation in acid and alkaline filtration applications.

Manufactured from imported Polypropylene Homopolymer (PPH) using one-piece injection molding, the AALBF-4A features a seamless, weld-free structure that completely eliminates leakage risks while delivering excellent mechanical strength and chemical resistance. Its lightweight construction, combined with UV-resistant additives, makes it suitable for both indoor and outdoor industrial environments.

Designed for standard Size #4 filter bags (φ105 × 380 mm), the AALBF-4A can also be converted into a single 10-inch cartridge filter housing, providing flexibility for process optimization. Fully compatible with internationally recognized filter bag brands such as EATON, FSI, and PALL, this housing ensures easy replacement and global availability of consumables.

With an operating pressure of up to 8 bar (116 psi) and temperature resistance up to 90°C (194°F), the AALBF-4A PPH Filter Housing is widely used in chemical processing, pharmaceuticals, electronics, electroplating, wastewater treatment, and other applications where metal housings are unsuitable.

Key Features

1. Compact Bag and Cartridge Filtration Design

Designed for Size #4 filter bags (φ105 × 380 mm) and convertible to hold one 10″ filter cartridge, the AALBF-4A allows users to flexibly switch between bag and cartridge filtration based on process requirements.

2. International Standard Compatibility

Manufactured to international standards, the housing is fully compatible with filter bags from global brands such as EATON, FSI, and PALL, as well as domestic standard filter bags, ensuring easy sourcing worldwide.

3. One-Piece Molded, Leak-Free Construction

The seamless one-piece molded body eliminates welding points entirely, providing superior structural integrity and zero liquid leakage risk, even under demanding operating conditions.

4. Premium Imported PPH Material

Constructed from imported Polypropylene Homopolymer (PPH), the housing offers excellent resistance to acids, alkalis, and most industrial chemicals. Optional materials such as PVDF, ETFE, and PFA are available for highly aggressive media.

5. UV-Resistant and All-Climate Durability

UV-resistant additives prevent material aging caused by sunlight exposure, allowing stable long-term operation in both indoor and outdoor installations.

6. Tool-Free Screw-Cap Operation

The screw-cap design enables quick opening and closing without tools, significantly reducing maintenance time and system downtime during filter replacement.

7. Polished Inner Surface

A smooth, polished interior minimizes chemical crystallization and residue accumulation, ensuring easy manual cleaning and consistent filtration performance.

8. Optimized Internal Flow Design

Carefully engineered spacing between the basket, housing wall, and bottom ensures smooth liquid flow, reduced turbulence, and lower pump energy consumption.

9. Precision Basket with Radial Sealing

The basket features a convenient handle for easy removal and installation. Its radial sealing design completely prevents internal bypass, meeting high-precision filtration requirements.

10. High Pressure and Temperature Resistance

Rated for operation at 116 psi (8 bar) and temperatures up to 194°F (90°C), the AALBF-4A delivers reliable performance in demanding industrial processes.

11. Robust Flanged Connections

Reinforced inlet and outlet flanges comply with international pipeline standards, ensuring secure installation and leak-free operation.

12. Wide Filtration Range

Supports filtration precision from 0.1 μm to 800 μm, covering both fine and coarse filtration needs across multiple industries.

13. Broad Industrial Applications

Widely applied in municipal wastewater treatment, copper and gold recovery, chemical processing, petroleum, bioengineering, pharmaceuticals, electronics, electroplating, industrial wastewater treatment, seawater desalination, dyeing, and papermaking industries.
