As industrial production volumes continue to increase, manufacturers require filtration systems capable of handling higher flow rates while maintaining consistent filtration efficiency. A 3 bag filter housing offers an ideal solution for medium to high-flow liquid filtration applications, providing greater dirt-holding capacity and longer service intervals than single-bag or dual-bag systems.
Designed to accommodate three filter bags within a single pressure vessel, a 3 bag filter housing significantly increases filtration area while reducing maintenance frequency and operating costs. It is widely used in industries such as water treatment, chemical processing, food and beverage manufacturing, pharmaceuticals, paints, coatings, and electronics production.
At Macrokun, we specialize in manufacturing premium-quality stainless steel bag filter housings for industrial customers worldwide. As an experienced manufacturer and supplier, we provide both standard and customized 3 bag filter housing systems designed to meet diverse process requirements.
This guide explains everything you need to know about 3 bag filter housings, including their working principle, advantages, applications, technical specifications, and selection criteria.

A 3 bag filter housing is a multi-bag filtration vessel engineered to hold three filter bags operating simultaneously. The incoming liquid is evenly distributed among the bags, allowing contaminants to be captured efficiently while maintaining high flow rates.
Compared with smaller bag filter systems, a 3 bag filter housing provides:
These advantages make it an excellent choice for facilities requiring continuous operation and large-scale liquid filtration.
The filtration process is simple yet highly effective.
Process liquid enters the housing through the inlet connection and is distributed evenly throughout the vessel.
The liquid flows through three filter bags simultaneously.
During this process, contaminants such as:
are captured inside the filter bags.
After passing through the filter media, the filtered liquid exits through the outlet connection.
When the pressure differential reaches the recommended limit, the filter bags are replaced quickly and easily, restoring optimal filtration performance.
One of the primary benefits of a 3 bag filter housing is its ability to handle significantly larger liquid volumes.
Typical flow capacities range from:
Actual performance depends on:
With three filter bags operating simultaneously, the total filtration surface area is substantially increased.
Benefits include:
Because contaminants are distributed across three bags, dirt loading per bag is lower.
This results in:
A 3 bag filter housing helps reduce overall operating expenses by:
The housing can accommodate a wide range of filter bag materials and micron ratings.
Common filtration ratings include:
This flexibility allows the system to meet the requirements of various industries and applications.
A 3 bag filter housing is commonly used in:
It effectively removes suspended solids and particulate contaminants.
Chemical manufacturers utilize multi-bag filter housings for:
The stainless steel construction offers excellent corrosion resistance and long service life.
Filtration is essential for maintaining product quality and safety.
Applications include:
Macrokun sanitary designs are available for food-grade applications.
Pharmaceutical facilities require reliable liquid filtration for:
High-quality filtration helps maintain process consistency and product purity.
A 3 bag filter housing effectively removes:
This improves coating quality and product consistency.
Precision manufacturing processes often require filtration of:
Efficient contaminant removal helps protect sensitive equipment and improve production yields.
