AAL UPVC Bag Filter Housing High-Precision, High-Flow and Corrosion-Resistant Filtration System

Product Overview

The AAL UPVC Bag Filter Housing is a high-performance liquid filtration solution engineered for applications requiring high filtration precision, large flow capacity, and superior corrosion resistance. Constructed from durable UPVC material, this bag filter housing offers long-term reliability in acidic and alkaline liquids, chemical processing, wastewater treatment, seawater and brackish water pretreatment, and reclaimed water reuse systems.

Designed to support both #1 (size 1) and #2 (size 2) filter bags, the unit is compatible with a wide range of bag materials and micron ratings, making it suitable for diverse industrial filtration needs. The top cover includes G1/4" threaded ports for easy installation of air vent valves and pressure gauges. Metric pressure gauges and PP diaphragm gauges are available upon request. With a maximum operating temperature of 45°C, the AAL UPVC Bag Filter Housing delivers a reliable, leak-free, and cost-effective filtration performance for modern water treatment applications.

Key Features

1. Excellent Corrosion Resistance

Constructed from 100% UPVC, it provides outstanding resistance to acids, alkalis, and corrosive liquids. Ideal for chemical filtration and aggressive industrial environments where metal housings fail.

2. Secure Locking Seal Design

A robust pressure plate and buckle-type sealing mechanism ensure reliable clamping and leak-free operation even under continuous pressure.

3. Innovative Anti-Collapse Internal Structure

Specially engineered to prevent the filter bag from collapsing into the basket, guaranteeing 100% leak-free performance and stable filtration efficiency.

4. Compact, Lightweight, and Easy to Operate

The compact footprint, aesthetic design, and lightweight structure make installation, filter bag replacement, and daily operation extremely convenient.

5. Wide Filtration Range (0.5–200 Microns)

Supports various process requirements—from coarse to fine filtration—making it suitable for multi-stage water treatment systems.

6. High Flow Capacity and Dirt-Holding Efficiency

Large filtration area ensures high flow rates and excellent contaminant retention, extending filtration cycles and reducing maintenance frequency.

7. Cost-Effective Alternative to Imported Systems

AAL’s UPVC bag filter housing provides comparable performance to imported models but at a significantly lower cost, delivering competitive value.
