Lightweight yet highly resistant to acids, alkalis, and most chemicals. Optional materials such as PVDF, ETFE, or PFA are available upon request.

5. UV-Resistant and Weatherproof Design

UV-resistant additives provide long-term durability, making the housing suitable for indoor and outdoor installations under various climates.

6. Swing Bolt Cover for Easy Operation

The swing bolt closure enables quick opening and secure tightening, even in confined spaces, simplifying filter bag and cartridge replacement.

7. Polished Inner Surface

A smooth interior surface prevents crystallization and residue buildup, facilitating easy manual cleaning and stable long-term performance.

8. Optimized Flow Dynamics

Enlarged spacing between the basket, inner wall, and bottom improves liquid flow, reduces pressure drop, and lowers pump energy consumption.

9. Precision Radial Sealing Basket

The handle-equipped basket allows quick removal and installation, while radial sealing prevents internal bypass for high-precision filtration.

10. High Pressure and Temperature Resistance

Rated for operating pressures up to 116 psi (8 bar) and temperatures up to 194°F (90°C).

11. Robust Flanged Connections

Durable flanged inlet and outlet connections ensure compatibility with international piping standards and secure installation.

12. Wide Micron Range

Supports filtration ratings from 0.1 to 800 microns, covering both coarse and fine filtration requirements.

13. Proven Industrial Applications

Widely applied in municipal wastewater treatment, copper and precious metal recovery, chemical and petrochemical processing, biotechnology, pharmaceuticals, electronics, electroplating, industrial wastewater, seawater desalination, textile dyeing, and paper manufacturing.

Why Choose AALBF-2B PPH / PVDF Filter Housing?

When compared with conventional stainless steel or metal filter vessels, the AALBF-2B PPH / PVDF Filter Housing offers distinct advantages in corrosive, high-purity, and cost-sensitive industrial applications:

Superior Chemical Resistance

Unlike metal housings that may suffer from corrosion, pitting, or chemical attack, PPH and PVDF materials provide outstanding resistance to acids, alkalis, salts, and most aggressive chemicals—ensuring long service life in harsh environments.

No Corrosion, No Contamination Risk

Metal filter housings can introduce metal ions or corrosion by-products into process liquids. The AALBF-2B’s non-metallic construction eliminates contamination risks, making it ideal for pharmaceutical, biotechnology, electronics, and ultrapure water applications.

Leak-Free One-Piece Molded Design

Traditional metal vessels rely on welded joints that may weaken over time. The AALBF-2B features a one-piece injection-molded body with no welds, ensuring excellent structural integrity and long-term leak-free operation.

Lightweight and Easy Handling

PPH / PVDF filter housings are significantly lighter than stainless steel vessels, reducing installation effort, simplifying maintenance, and lowering overall system load—especially beneficial for large-size or high-capacity filtration systems.

Lower Total Cost of Ownership

Compared to metal filter housings, the AALBF-2B requires less corrosion protection, fewer maintenance interventions, and no costly surface treatments, resulting in reduced operating and lifecycle costs.

Optimized for High-Flow Industrial Filtration

Designed for long filter bags, multiple cartridges, and high-flow cartridges, the AALBF-2B delivers high throughput with low pressure drop—matching or exceeding the performance of metal vessels in many industrial processes.

Flexible Material Options for Different Media

While PPH is suitable for most chemical and water treatment applications, optional PVDF, ETFE, or PFA materials are available for higher temperature or more aggressive chemical environments, offering flexibility beyond standard metal solutions.

A Smart Alternative to Metal Filter Vessels

For applications involving corrosive liquids, high chemical purity, frequent maintenance, or outdoor installation, the AALBF-2B PPH / PVDF Filter Housing is a proven, reliable, and economical alternative to stainless steel filter vessels.

Reliable Chemical-Resistant Filtration for High-Flow Applications

Engineered for durability, efficiency, and operational flexibility, the AALBF-2B PPH Filter Housing delivers stable and long-lasting filtration performance in the most demanding industrial environments.
