What Is an 8 Bag Filter Housing?

An 8 bag filter housing is a multi-bag filtration vessel designed to hold eight filter bags simultaneously. The incoming liquid is distributed evenly throughout the housing, allowing each filter bag to contribute to the filtration process.

Compared with smaller filtration systems, an 8 bag configuration offers:

  • Significantly higher flow rates
  • Increased dirt-holding capacity
  • Longer service intervals
  • Lower operating costs
  • Improved process efficiency

Because of these advantages, 8 bag filter housings are commonly used in facilities with continuous production processes and large liquid handling requirements.


How Does a Multi Bag Filter Housing Work?

The operating principle is straightforward yet highly effective.

Step 1: Liquid Enters the Housing

Contaminated liquid enters the vessel through the inlet connection and flows into the upper chamber.

Step 2: Even Flow Distribution

The housing’s internal design ensures equal liquid distribution across all eight filter bags.

Uniform flow distribution provides:

  • Consistent filtration performance
  • Reduced pressure loss
  • Maximum filter bag utilization

Step 3: Contaminant Removal

As liquid passes through the filter media, unwanted particles are retained inside the bags.

Typical contaminants include:

  • Sand
  • Sediment
  • Rust
  • Process debris
  • Suspended solids
  • Product impurities

Step 4: Clean Liquid Discharge

Filtered liquid collects in the lower chamber and exits through the outlet connection.

Step 5: Filter Bag Replacement

When differential pressure reaches the recommended level, the filter bags can be replaced quickly, minimizing system downtime.


Advantages of an 8 Bag Filter Housing

Extremely High Flow Capacity

One of the most important benefits of an 8 bag filter housing is its ability to process very large liquid volumes.

Typical flow capacities range from:

  • 150–350 m³/h
  • Higher capacities for custom-engineered systems

Actual performance depends on:

  • Bag size
  • Filtration rating
  • Fluid viscosity
  • Contaminant loading

For large-scale manufacturing facilities, this capacity can significantly improve productivity.


Maximum Filtration Area

The eight-bag configuration provides a large filtration surface area that helps reduce system pressure drop and improve contaminant retention.

Benefits include:

  • Better filtration efficiency
  • Higher contaminant capacity
  • Longer filter bag life
  • Improved system stability

Compared with a single bag filter housing, an 8 bag filter housing can provide up to eight times the filtration area.


Lower Maintenance Requirements

Because contaminants are distributed across multiple bags, each filter bag experiences a lower dirt-loading rate.

This results in:

  • Fewer filter bag replacements
  • Reduced labor costs
  • Less downtime
  • Lower maintenance expenses

Over the life of the system, these savings can be substantial.


Improved Equipment Protection

Effective filtration helps protect critical downstream equipment, including:

  • Pumps
  • Heat exchangers
  • Spray nozzles
  • Membrane systems
  • Production machinery

This reduces maintenance costs and extends equipment service life.


Space-Saving Design

Installing a single 8 bag filter housing is often more efficient than using multiple smaller filtration units.

Advantages include:

  • Reduced installation footprint
  • Simplified piping
  • Easier maintenance
  • Lower equipment costs
