100 Micron Liquid Filter Bag for Coarse Industrial Filtration and High-Flow Pre-Filtering

A 100 micron liquid filter bag is a high-flow filtration solution designed to remove large particles, sediment, rust, fibers, gels, scale, and visible suspended solids from industrial liquids. It is commonly used as the first filtration stage in water treatment, chemical processing, coatings, inks, oils, food processing, wastewater pre-treatment, and general industrial liquid filtration systems.

Compared with 10 micron, 20 micron, or 50 micron filter bags, a 100 micron filter bag provides coarser filtration. Its main advantage is not ultra-fine particle removal, but higher flow rate, lower pressure drop, longer service life, and better performance in liquids with heavy solids loading. For factories that need to remove larger contaminants before finer filtration, a 100 micron liquid filter bag is often the right starting point.

Macrokun is a professional liquid filter bag manufacturer and supplier, offering 100 micron filter bags in PP, polyester, PE, nylon mesh, and customized filtration materials. We support standard sizes, custom dimensions, OEM production, private label packaging, and bulk supply for global industrial users and distributors.

What Is a 100 Micron Liquid Filter Bag?

A 100 micron liquid filter bag is designed to capture particles around 100 microns and larger from a liquid stream. In industrial filtration, 100 micron is usually considered a coarse filtration grade. It is suitable for removing large visible contaminants before the liquid enters pumps, spray nozzles, valves, cartridge filters, membrane systems, heat exchangers, or finer filter bags.

Because the pore size is larger than 50 micron, 25 micron, or 10 micron filtration, a 100 micron filter bag allows liquid to pass through with lower resistance. This makes it suitable for high-flow systems, dirty liquids, circulation loops, wastewater, and processes where quick clogging is a concern.

A 100 micron liquid filter bag can be installed in standard bag filter housings, multi-bag filter housings, open filtration tanks, custom filtration vessels, and circulation filtration systems.

Why Choose a 100 Micron Filter Bag?

The main reason to choose a 100 micron filter bag is operating efficiency. When a liquid contains heavy contamination or large particles, using a very fine filter bag at the first stage can cause fast clogging, high pressure drop, reduced flow, and frequent replacement. A 100 micron liquid filter bag solves this problem by removing larger solids first.

Key benefits include:

• High flow rate for large-volume liquid processing
• Low pressure drop compared with finer filter bags
• Longer service life in dirty liquids
• Effective removal of visible particles and large suspended solids
• Reduced load on downstream finer filters
• Protection for pumps, valves, spray nozzles, and heat exchangers
• Lower maintenance frequency
• Cost-effective first-stage filtration

For many industrial systems, a 100 micron filter bag is not the final filtration step. It is the protective first step that makes the whole filtration process more stable.

Typical Applications of 100 Micron Liquid Filter Bags

A 100 micron liquid filter bag is suitable for coarse particle removal and pre-filtration in many industries.

Industrial Water and Process Water Filtration

In industrial water systems, a 100 micron filter bag can remove sand, pipe scale, rust flakes, sediment, algae fragments, and large suspended particles. It is commonly used in cooling water systems, circulating water filtration, process water treatment, wastewater pre-treatment, and water recycling systems.

When installed before finer filters, the 100 micron liquid filter bag reduces the solids load and helps prevent premature clogging of cartridge filters or membrane systems.

Wastewater Pre-Treatment

Wastewater often contains mixed impurities such as fibers, sludge, grit, plastic fragments, organic residues, and process debris. A 100 micron liquid filter bag can be used as a practical pre-treatment step to remove larger particles before downstream treatment.

This can help improve system stability, reduce equipment blockage, and lower the replacement frequency of finer filtration elements.

Chemical Processing

Chemical liquids may carry undissolved raw material particles, gel pieces, tank debris, catalyst residue, and process contamination. A 100 micron filter bag is useful when the first goal is to remove large unwanted solids before finer filtration or packaging.

For chemical applications, choosing the correct material is important. PP filter bags are often suitable for many acids and alkalis, while polyester, nylon, or special materials may be better for higher temperature or specific solvent conditions.

Paints, Coatings, Resins, and Ink Production

In paint, coating, resin, and ink production, large particles can cause quality problems, nozzle blockage, uneven coating, and visible defects. A 100 micron liquid filter bag can remove larger agglomerates, skins, fibers, gels, and coarse impurities before the product moves to finer filtration or filling.

For many coating lines, 100 micron filtration is used as the first screening stage, followed by 50 micron, 20 micron, or 10 micron filtration when cleaner product output is required.

Oil, Lubricant, and Cutting Fluid Filtration

Industrial oils, lubricants, hydraulic fluids, cutting fluids, and process oils can contain metal chips, dust, sludge, carbon particles, and larger debris. A 100 micron filter bag helps remove coarse contaminants and protect circulation pumps, valves, hydraulic systems, and processing equipment.

For viscous liquids, 100 micron filtration can be more practical than very fine filtration because it keeps lower resistance and better flow.

Food and Beverage Coarse Filtration

In food and beverage processing, a 100 micron liquid filter bag may be used for removing larger suspended solids from edible oils, syrups, sauces, beverages, process water, and liquid ingredients. It can also be used before finer filtration or clarification steps.

For food-related applications, customers should confirm material safety, cleanliness requirements, and process standards before selecting a filter bag.

Surface Treatment and Plating Solutions

In plating, surface treatment, and cleaning systems, particles can accumulate in circulation tanks and affect product quality. A 100 micron filter bag can remove larger particles, metal residues, tank debris, and suspended solids from circulating liquids.

This helps improve bath cleanliness and reduce equipment blockage.

Material Options for 100 Micron Filter Bags

Macrokun can manufacture 100 micron liquid filter bags in different materials according to liquid type, temperature, chemical compatibility, and filtration method.

100 Micron PP Filter Bag

A 100 micron PP filter bag is made from polypropylene felt or polypropylene mesh. It is widely used for water treatment, chemical liquids, plating solutions, wastewater, and general industrial filtration.

Polypropylene is lightweight, economical, and resistant to many acids and alkalis. It is often the first choice for customers who need cost-effective disposable filtration bags.

100 Micron Polyester Filter Bag

A 100 micron polyester filter bag provides good strength and better temperature resistance than PP in many applications. It is commonly used for oils, coatings, inks, resins, lubricants, and process liquids.

Polyester felt is suitable for depth filtration, while polyester mesh may be used for surface filtration depending on the application.

100 Micron Nylon Mesh Filter Bag

A 100 micron nylon mesh filter bag is one of the most popular options for washable and reusable coarse filtration. Nylon mesh has a clear pore structure, good flow performance, and strong particle separation ability.

It is often used when customers need to capture larger particles, recover solids, clean the filter bag after use, or reduce disposable filter cost.

Custom 100 Micron Liquid Filter Bag

Macrokun can also produce custom 100 micron filter bags based on customer drawings, samples, housing dimensions, filtration vessels, or special process requirements. Customization can include diameter, length, top ring, drawstring, handle, bottom shape, sewing method, welded structure, packaging, and label design.

100 Micron vs 50 Micron Filter Bag

A 100 micron filter bag is coarser than a 50 micron filter bag. It allows higher flow and generally provides longer service life in dirty liquids, but it captures larger particles only.

A 50 micron liquid filter bag removes smaller particles and provides cleaner output than 100 micron. However, it may clog faster when the liquid has heavy suspended solids.

For high-solids liquids, a common staged filtration method is to use 100 micron first, then 50 micron, and then 20 micron or 10 micron if finer filtration is required. This approach reduces the load on each stage and improves total filtration efficiency.

100 Micron vs 200 Micron Filter Bag

A 200 micron filter bag is coarser than 100 micron and is usually used for very large debris, heavy particles, or rough screening. It provides very high flow but lower particle removal accuracy.

A 100 micron liquid filter bag is a better choice when the process still needs coarse filtration but requires cleaner output than 200 micron can provide. It is often used as a more controlled first-stage filter for general industrial liquids.

100 Micron vs 20 Micron Filter Bag

A 20 micron filter bag is used for finer particle removal. It is suitable when the liquid needs better clarity and stronger downstream protection.

A 100 micron filter bag is used for coarse filtration and high-flow pre-filtering. It should not be used as a replacement for 20 micron filtration when fine particles must be removed. Instead, it works best as the first stage before a 20 micron or 10 micron filter bag.

How to Choose the Right 100 Micron Liquid Filter Bag

Selecting the correct 100 micron filter bag requires a clear understanding of the filtration goal.

1. Confirm Whether You Need Coarse Filtration

A 100 micron liquid filter bag is best for removing larger particles, not for fine polishing. If your liquid contains visible sediment, rust, fibers, scale, gels, or process debris, 100 micron may be suitable.

2. Check the Solids Loading

If the liquid is dirty or has high solids content, 100 micron can provide longer service life than finer filter bags. If the liquid is already relatively clean but needs fine particle control, a lower micron rating may be required.

3. Choose the Correct Material

PP is suitable for many water and chemical applications. Polyester is often selected for higher temperature, oils, coatings, and stronger mechanical conditions. Nylon mesh is ideal for washable surface filtration and particle separation.

4. Match the Housing Size

The filter bag must fit the housing properly. A poor fit can cause bypass, unstable sealing, and reduced filtration performance. Standard sizes such as #1 and #2 are common, but custom sizes are available for non-standard equipment.

5. Consider Flow Rate and Pressure Drop

One major advantage of a 100 micron filter bag is high flow performance. For large-volume filtration systems, the correct bag size and housing design are important to keep pressure drop within a safe operating range.

6. Decide Between Disposable and Reusable Options

PP and polyester felt bags are often used as disposable filter bags. Nylon mesh and some polyester mesh bags may be washed and reused depending on the application. The right choice depends on operating cost, cleaning method, and process requirements.
