AALBF-2C High-Capacity Size #2 Top-Entry PPH Bag Filter Housing for Industrial Filtration

The AALBF-2C Top-Entry PPH Filter Housing, developed and manufactured by AAL Filter, is a high-capacity top-entry (top-loading) bag-type liquid filtration housing engineered for large flow rates, aggressive chemicals, and continuous industrial operation.

Manufactured from premium imported Polypropylene Homopolymer (PPH) using one-piece injection molding technology, the housing features a seamless, weld-free structure. Combined with its top-entry filtration design, this construction effectively eliminates leakage risks and internal bypass, ensuring consistent and reliable filtration performance.

The AALBF-2C adopts a top-in / bottom-out flow configuration, allowing liquid to enter from the top and flow through the filter bag or cartridge in a controlled vertical direction. This top-loading design minimizes turbulence, prevents bag misalignment, and improves filtration stability—making it ideal for applications requiring high precision and operational reliability.

Designed for standard Size #2 filter bags (φ180 × 810 mm), the AALBF-2C also supports multiple 20-inch top-entry cartridge configurations, including multi-cartridge arrangements or a single high-flow cartridge. This flexibility allows easy switching between bag and cartridge filtration based on process requirements.

Fully compatible with globally recognized brands such as EATON, FSI, and PALL, the AALBF-2C is widely used in municipal water treatment, chemical processing, electronics, electroplating, pharmaceuticals, food & beverage production, industrial wastewater treatment, and seawater desalination systems.

Key Features

1. Top-Entry (Top-Loading) Filtration Design

Top-in / bottom-out flow configuration reduces internal bypass and turbulence, ensuring stable and reliable filtration performance.

2. High-Capacity Size #2 Bag Filtration

Designed for standard Size #2 filter bags (φ180 × 810 mm), ideal for high-flow applications and extended service life.

3. Dual Compatibility: Top-Entry Bags & 20″ Cartridges

Supports multiple top-loading filtration options:

● Six 20″ cartridges (OD 62 mm)

● Five 20″ cartridges (OD 68 mm)

● One 20″ high-flow filter cartridge

4. International Standard Compatibility

Compatible with filter bags from EATON, FSI, PALL, and other international or domestic brands.

5. One-Piece Molded, Weld-Free Housing

Seamless construction provides superior mechanical strength and completely eliminates leakage risks.

6. Premium PPH Construction

Lightweight yet highly resistant to acids, alkalis, and most industrial chemicals. Optional materials include PVDF, ETFE, and PFA.

7. UV-Resistant & Weatherproof

UV-resistant additives ensure long-term durability for both indoor and outdoor installations.

8. Top-Entry Swing Bolt Cover Design

Swing bolt top cover allows quick opening and tightening, even in confined spaces, simplifying maintenance and bag replacement.

9. Polished Inner Surface

Smooth internal finish prevents crystallization and residue buildup, making cleaning easier.

10. Optimized Flow Path for Energy Efficiency

Enlarged internal spacing combined with top-entry flow reduces pressure drop and pump energy consumption.

11. High-Precision Radial Sealing Basket

Handle-equipped basket enables easy top removal; radial sealing design prevents internal bypass.

12. High Pressure & Temperature Rating

Rated up to 116 psi (8 bar) and 194°F (90°C) for demanding industrial conditions.

13. Flanged Inlet & Outlet Connections

Reinforced flanged connections ensure compatibility with international piping standards.

14. Wide Filtration Range

Supports filtration ratings from 0.1 μm to 800 μm.
