Overview

Industrial filter bags separate solids from liquids in various systems, such as water treatment plants and food production lines. Selecting the right filter bag helps your system run more efficiently, reduces strain on equipment and reduces maintenance and replacement costs.

In this guide, we discuss how to choose industrial filter bags by covering the key factors to consider before selecting a filter bag for your application.

Key Factors to Consider When Choosing a Filter Bag

Micron Rating

The micron rating refers to the size of particles a filter bag can remove. For example, a 5-micron bag will filter out much finer debris than a 100-micron one. Think of it like sieves with different mesh sizes.

In case of doubt, go for a smaller micron and adjust based on results.

Filter Media Material

Filter bags are made from different materials. Some materials perform better in high temperatures. Others are more suitable for handling chemical exposure or capturing finer particles.

Choosing the right media extends the life of your filtration system and improves its performance.

Chemical Compatibility

Not all filter bags industrial systems use can handle every fluid. Some materials don’t hold up well when exposed to acids, bases or solvents. Ensure the bag material suits the chemicals in your system to avoid damage or contamination.

Temperature Tolerance

Each filter media has a maximum working temperature. For instance, Polypropylene works for temperatures up to 95°C. Polyester is better for hotter liquids, holding up to 150°C. Exceeding these limits can cause the bag to warp or fail.

Size

Filter bags come in standard sizes. Size 1 bags are about 410mm long, while Size 2 bags are around 810mm long. Larger bags hold more contaminants and need fewer changeouts.

Make sure your choice matches your industrial bag filter housing and the flow rate of your system. Learn more about our available stainless bag filter housings and polypropylene bag filter housings.

Collar Type

Most industrial filter bags come with either a metal ring or a plastic collar. Plastic collars are often preferred for water filtration as they are non-corrosive and easier to handle. They’re also lighter, reduce the risk of damage during installation, and make routine maintenance faster — especially in systems that require frequent filter changes.

Application Type

The needs of each industry vary. The food and beverage industry may require FDA-compliant materials. For chemical processing, the focus might be on compatibility and filtration efficiency. Always choose filter bags that are purpose-built for your application.

For instance, in pharmaceutical systems, finer filtration and compliant materials are often required. Mining setups, on the other hand, prioritise strength and the ability to handle higher flow rates.

Common Mistakes to Avoid

Remember these common mistakes people make when choosing filter bags and why it's important to avoid them.

  • Ignoring chemical compatibility: Choosing the wrong material can lead to early failure or contamination.
  • Incorrect micron rating: A filter that is too coarse will not catch the right particles. One that is too fine may clog too quickly.
  • Choosing the wrong size: A mismatch between the bag and housing can reduce efficiency or cause leakage.
  • Overlooking flow rate: Not all filter bags suit high-volume systems. Make sure the bag can handle your flow requirements.
