Bag Filter Vessels for Industrial Liquid Filtration

High-Efficiency, Cost-Effective Filtration Solution for Industrial Applications

Bag filter vessels are widely used in industrial liquid filtration processes to remove solid particles, impurities, and contaminants from fluids. Designed for high flow rates, easy operation, and low maintenance, they provide a reliable and economical solution for industries such as water treatment, chemical processing, food & beverage, pharmaceuticals, and oil & gas.

Our bag filter housings are engineered with durable construction, flexible configurations, and high filtration efficiency, ensuring consistent performance in demanding environments.

What Is a Bag Filter Vessel?

A bag filter vessel (bag filter housing) is a pressure filtration system that uses a filter bag to capture solid particles from liquids.

The system typically consists of:

  • Filter housing (vessel body)

  • Filter bag (filtration medium)

  • Support basket

  • Inlet and outlet connections

It is ideal for coarse to fine filtration (1–2000 microns) and large-volume liquid processing.

Working Principle of Bag Filter Vessel

1. Liquid Inlet
The fluid enters the vessel through the inlet pipe.

2. Filtration Process

• Liquid flows into the filter bag

• Solid particles are trapped inside the bag

• Clean liquid passes through and exits

3. Collection & Discharge

• Contaminants accumulate inside the bag

• Bag is replaced or cleaned when full

This simple yet effective process ensures high dirt-holding capacity and stable filtration performance.

Types of Bag Filter Vessels

▶ Single Bag Filter Vessel

  • Designed for low to medium flow rates

  • Compact and cost-effective

  • Easy installation

Best for small-scale applications

▶ Multi-Bag Filter Vessel

  • Holds multiple filter bags (2–24 bags)

  • Suitable for high flow rates and large systems

Ideal for:

  • Industrial plants

  • Water treatment systems

▶ Top Entry Bag Filter Housing

  • Bag loaded from top

  • Better sealing and leak prevention

Common in high-purity applications

▶ Side Entry Bag Filter Housing

  • Bag accessed from side

  • Faster maintenance and replacement

Preferred for industrial efficiency

▶ Duplex Bag Filter System

  • Two vessels operate alternately

  • Continuous filtration without shutdown

Suitable for:

  • Critical processes requiring uninterrupted operation
