What is a Bags Filter and How it Works?

A Bags filter is a filtration system used in industrial processes to separate solid particles from liquids using a replaceable filter medium. The liquid enters the housing, passes through the filter bag, and leaves contaminants trapped inside while the cleaned fluid flows out. The bag is positioned within a vessel and supported by a perforated basket to maintain stability during operation.

In applications where steady flow and controlled particle retention are critical, a Bags filter gives dependable performance. It is commonly used in water treatment, chemical processing, oils, and coolants to safeguard equipment and maintain operational balance. Maintenance is straightforward, making it practical for plants managing continuous production.

A Bags filter can retain particles either on the surface (mesh style) or within the depth of the felt media, depending on process requirements.
Most Bags filter systems operate on an inside-to-outside flow design to ensure efficient solids containment.
A Bags filter is suitable for viscous liquids and fluids exposed to chemical stress when paired with appropriate media.
Bags filter options are available in multiple micron ratings, covering coarse separation to fine filtration stages.
A Bags filter reduces particulate impact on pumps, membranes, spray systems, and heat exchangers.
Compared to cartridge setups, a Bags filter can provide a more cost-effective solution for large-scale liquid filtration.

Bags Filter
by Micron Rating

Micron rating is one of the most important factors when specifying a Bags filter for an industrial process. A micron is a very small unit of measurement used to describe particle size, and it tells you what range of solids the filter bag is intended to retain. The right choice depends on the process fluid, the type of solids present, and the required cleanliness of the outlet stream.

Finer micron selections can improve clarity, but they also change how the system behaves in real operation. Media structure, solids loading, and flow rate all influence pressure build-up and service life. Factoring these variables early helps you select a Bags filter that performs consistently and reduces frequent change-outs.

Nominal vs. Absolute Rating

Nominal ratings indicate typical capture efficiency at a stated size, while absolute ratings are defined for more precise retention where tighter control is required.

Get the Right Bag Filter

Micron Rating :

1–5 micron filters

Used where a Bags filter is required to capture very fine particles in polishing or final-stage processes, especially where downstream equipment demands tighter particulate control.
10–25 micron filters

Selected when a Bags filter needs to manage moderate contamination levels in process liquids while maintaining stable flow conditions.
50–100 micron filters

Commonly applied in Bags filter systems for sediment reduction and pre-filtration in water treatment, coolants, and general industrial liquid handling.
150–200 micron filters

Specified in Bags filter applications where larger suspended solids or debris must be separated efficiently from the liquid stream.

Bags Filter by Size (Standard Industry Sizing)

Just like micron choice, bag size decides whether a Bags filter seals correctly, holds a stable flow rate, and runs efficiently on the floor. Standard bag housings are typically referenced as Size 1 through Size 6, and each number maps to a specific diameter and length for that housing. When the wrong size is fitted, the bag can sit unevenly, lose its seal, allow bypass, or create avoidable pressure issues, so confirming size is essential before you place a purchase order for a Bags filter system.

For faster selection, share your housing size, liquid type, and target micron rating; our team can recommend the most suitable Bags filter.

Custom Sizes: mmp can manufacture Bags filter bags in specific lengths or diameters when an application needs a non-standard dimension.
Application-Based Selection: If sizing is uncertain, cross-checking the housing drawing/spec sheet is the fastest way to confirm fit and get the expected performance from your Bags filter.

FAQs: Bags Filter

What are Bags Filter?

A Bags filter acts on a liquid stream by filtering out the solid contaminants by using a bag-type filter that is housed inside a bag filter housing. As the liquid passes through the housing, the bag will retain specific contaminants according to their size in microns, while allowing the clean fluid to pass out of the bag to provide control over the solids and protection of all downstream equipment. Bags filters or bag filters have many applications, including the treatment of water, the processing of chemicals, the production of food, and the processing of oil. Due to the high flow rate and low cost-effectiveness of the bag filters, as well as the ability of the bag filters to hold on to dirt for longer service intervals.

What is the composition of industrial filter bags?

For filtering applications, industrial filter bags are usually composed of polypropylene, polyester, nylon, PTFE, or specialty media, depending on application requirements. In general, polypropylene is selected for applications requiring chemical resistance, while polyester is often used for processing oil-based liquids. Nylon is frequently chosen for applications that require abrasion resistance; PTFE is typically selected for applications that involve extreme temperature and/or corrosive processing conditions. Ultimately, the material actually used is determined by operating temperature, system pressure, and compatibility with the solution being filtered.

What is a Bags filter used for?

A Bags filter is used to remove solid particles from liquids. The liquid passes through a filter bag inside a housing, solids remain in the bag, and the filtered liquid exits the system. It’s commonly used in water treatment, chemicals, oils, coolants, and other industrial process liquids.

How do I pick the right micron rating for a Bags filter?

Start with what you’re trying to stop. If you need coarse removal, higher microns work; if you need clearer output, go lower. A Bags filter micron choice also depends on flow rate, solids load, and how often you want to change the bag. Share your liquid and target result, and selection becomes easy.

What’s the difference between nominal and absolute in a Bags filter?

Nominal means the bag captures “most” particles at that micron size, but not all. Absolute is tighter and more consistent. If your process needs predictable filtration quality, an absolute-rated Bags filter is usually the safer choice.

Which material should I choose for a Bags filter bag?

It depends on your fluid and operating conditions. Polypropylene is often used for chemical resistance; polyester works well with many oils; nylon handles abrasion better; and PTFE is selected for high-temperature or corrosive-duty applications. The right Bags filter material is always based on compatibility.

What are the standard sizes for a Bags filter?

Most bag housings use standard sizes like Size 1 and Size 2, while other sizes are used in special housings. A Bags filter must match your housing length, diameter, and sealing ring type; otherwise, you can get leakage or bypass.

Why does my Bags filter clog too fast?

Usually, it’s because the micron rating is too fine for the solids load, the media isn’t suited to the liquid, or the flow is higher than the bag can handle. In many cases, switching to a staged setup (coarse then fine) or changing the Bags filter media improves run time.

How much flow can a Bags filter handle?

A Bags filter can handle high flow, but capacity depends on bag size, micron rating, viscosity, and contamination level. For accurate sizing, you should match your flow rate and acceptable pressure drop with the bag and housing specifications.

Can I get a custom Bags filter for my housing?

Yes. A Bags filter can be made in custom sizes, micron ratings, media types, and sealing ring styles. Custom supply is common when housings are non-standard or when the process has specific temperature, chemical, or compliance requirements.

When should I replace a Bags filter?

Most plants replace a Bags filter when differential pressure rises, flow drops, or filtration quality starts to change. The best approach is to set a replacement point based on performance, not just time, and align it with your maintenance schedule.

Do you supply Bags filter in bulk for plants and distributors?

Yes. Bags filter is often purchased in bulk to maintain spares and avoid downtime. If you share your required sizes, micron ratings, and monthly consumption, we can plan a consistent supply for your plant, projects, or distribution network.
