Industrial liquid filtration is essential for maintaining product quality, protecting downstream equipment, and improving production efficiency. Among the many filtration solutions available, the 1 bag filter housing remains one of the most widely used systems due to its simplicity, cost-effectiveness, and high dirt-holding capacity.
Whether you operate in water treatment, chemicals, food processing, pharmaceuticals, or electronics manufacturing, a single bag filter housing can provide reliable filtration while minimizing maintenance costs.
As a professional manufacturer and supplier, Macrokun specializes in high-quality stainless steel bag filter housings with customizable configurations to meet various industrial requirements. In this guide, we’ll explore everything you need to know about single bag filter housing systems, including their advantages, applications, technical specifications, and selection considerations.

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:
Compared with cartridge filtration systems, a single bag filter housing often provides greater contaminant loading capacity and requires fewer filter change-outs.
The filtration process is straightforward:
The liquid enters through the inlet connection and flows into the housing chamber.
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.
Filtered liquid leaves through the outlet connection and continues downstream.
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.
Single bag systems provide excellent filtration efficiency at a lower operating cost than many alternative technologies.
Benefits include:
A standard filter bag offers significantly more contaminant retention than most cartridge filters.
Advantages include:
A single bag filter housing can handle substantial liquid volumes while maintaining low pressure drop.
Typical flow capacities range from:
Actual flow rates depend on:
Top-opening designs allow operators to replace bags quickly.
Maintenance usually requires:
This process typically takes only a few minutes.
