1 Bag Filter Housing: The Complete Guide to Single Bag Filter Housing Systems


What Is a 1 Bag Filter Housing?

A 1 bag filter housing, also known as a single bag filter housing, is a pressure vessel designed to hold one filter bag for liquid filtration applications.

The housing directs liquid through a filter bag where contaminants, particles, sediments, and impurities are captured. Clean liquid then exits through the outlet port while solids remain trapped inside the filter bag.

Single bag filter housings are widely preferred because they combine:

  • High flow rates
  • Large dirt-holding capacity
  • Easy bag replacement
  • Low operating costs
  • Compact installation footprint

Compared with cartridge filtration systems, a single bag filter housing often provides greater contaminant loading capacity and requires fewer filter change-outs.


How Does a Single Bag Filter Housing Work?

The filtration process is straightforward:

Step 1: Contaminated Liquid Enters

The liquid enters through the inlet connection and flows into the housing chamber.

Step 2: Filtration Through the Bag

The liquid passes from the inside to the outside of the filter bag.

Particles larger than the filter bag‘s micron rating are retained inside the bag.

Step 3: Clean Liquid Exits

Filtered liquid leaves through the outlet connection and continues downstream.

Step 4: Bag Replacement

When differential pressure reaches the recommended limit, the filter bag is replaced, restoring optimal filtration performance.

This simple operating principle makes the 1 bag filter housing ideal for continuous industrial filtration processes.


Advantages of 1 Bag Filter Housing

1. Cost-Effective Filtration

Single bag systems provide excellent filtration efficiency at a lower operating cost than many alternative technologies.

Benefits include:

  • Affordable filter bags
  • Reduced maintenance labor
  • Lower replacement frequency
  • Minimal downtime

2. Large Dirt-Holding Capacity

A standard filter bag offers significantly more contaminant retention than most cartridge filters.

Advantages include:

  • Longer service life
  • Reduced bag changes
  • Improved process efficiency
  • Lower consumable costs

3. High Flow Rate Capability

A single bag filter housing can handle substantial liquid volumes while maintaining low pressure drop.

Typical flow capacities range from:

  • 5 to 40 m³/h for Size #1 bags
  • 20 to 80 m³/h for Size #2 bags

Actual flow rates depend on:

  • Liquid viscosity
  • Micron rating
  • Contaminant concentration
  • Operating pressure

4. Easy Maintenance

Top-opening designs allow operators to replace bags quickly.

Maintenance usually requires:

  • Opening the lid
  • Removing the used bag
  • Installing a new filter bag
  • Closing and restarting the system

This process typically takes only a few minutes.


5. Multiple Material Options

Macrokun offers:

  • Stainless Steel 304
  • Stainless Steel 316L
  • Carbon Steel
  • Customized alloy materials

These options ensure compatibility with different process fluids and operating environments.
