Filter Bags
Aris Filtration manufactures and exports industrial Filter Bags for efficient liquid, process, pharmaceutical, and dust filtration applications. These filter bags are available in materials such as polypropylene, polyester, nylon, cotton, needle felt, monofilament, multifilament and Nomex, with filtration ratings selected according to the process requirement.
What Are Filter Bags?
Filter Bags are filtration media designed to separate suspended particles, contaminants and solids from liquids, process fluids or industrial air streams. They are installed in compatible filter housings or filtration equipment, where contaminated fluid passes through the filter media and retained particles are collected within or on the bag.
Filter bag selection depends on factors such as:
- Type of fluid or gas
- Particle characteristics
- Required micron rating
- Flow rate
- Operating temperature
- Operating pressure
- Chemical compatibility
- Dirt or solids loading
- Required filtration efficiency
- Filter housing configuration
Aris Filtration approaches filter selection as a complete filtration-system requirement, rather than selecting a filter bag only on the basis of micron rating.
What Types of Filter Bags Does Aris Filtration Offer?
The Filter Bags product category can be organized into application-specific filtration solutions:
| Filter Bag Type | Primary Application |
|---|---|
| Liquid Filter Bags | Liquid and process-fluid filtration |
| Process Filtration Bags | Industrial process and chemical filtration |
| FBD Filter Bags | Fluid Bed Dryer/Processor applications |
| Centrifuge Filter Bags | Solid-liquid separation in centrifuge systems |
| Dust Collection Filter Bags | Industrial dust and particulate collection |
This pillar page covers the overall Filter Bags category, while individual supporting pages can provide detailed information about each specialized filter bag type.
How Do Industrial Filter Bags Work?
A filter bag works by providing a controlled filtration path between the contaminated stream and the clean outlet.
The typical filtration process is:
- Feed entry: Contaminated liquid or air enters the filtration equipment.
- Flow through media: The process stream passes through the filter bag.
- Particle retention: Suspended solids and unwanted particles are retained by the filtration media.
- Clean-stream discharge: The filtered liquid or air leaves the filtration system.
- Bag replacement: The filter bag is removed and replaced when its contaminant-holding capacity is reached.
A correctly selected filter bag can help control particulate contamination while supporting consistent process flow and protecting downstream equipment.
What Materials Are Used for Filter Bags?
Different filtration applications require different media. Aris Filtration provides filter bags using multiple material options, depending on process conditions.
Common Filter Bag Materials
- Polypropylene (PP): Suitable for many liquid filtration and chemical-processing applications.
- Polyester: Used where suitable mechanical strength and process compatibility are required.
- Nylon: Used for applications requiring appropriate strength and chemical compatibility.
- Cotton: Used for selected filtration applications.
- Needle Felt: Provides depth-style filtration and can be selected for applications involving higher solids loading.
- Monofilament Media: Suitable where controlled surface filtration and particle retention are required.
- Multifilament Media: Provides a different filtration structure for selected liquid applications.
- Nomex: Used for selected high-temperature industrial filtration requirements.
The correct material should always be selected according to the fluid chemistry, temperature, pressure, particle characteristics and required filtration performance.
What Micron Ratings Are Available for Filter Bags?
Aris Filtration's liquid filter bags are available in filtration ratings from 1 micron to 150 microns, with commonly listed ratings including 1, 2, 5, 10, 25, 50, 100 and 150 microns.
| Parameter | Aris Filtration Liquid Filter Bags |
|---|---|
| Micron Rating | 1–150 micron (1, 2, 5, 10, 25, 50, 100, 150 µm) |
| Standard Sizes | 4" × 10", 4" × 20", 7" × 16", 7" × 32" |
| Custom Sizes | Available based on requirement |
| Collar/Fitting Options | PP Collar, SS Ring, Snap Band, Rubber Collar |
| Construction | Stitched / Welded |
| Media Options | PP, Polyester, Nylon, Cotton, Needle Felt, Monofilament, Multifilament, Nomex |
| Application | Liquid and process filtration |
Micron rating should not be considered independently; the actual filtration requirement, particle distribution, flow rate and contaminant loading should also be evaluated.

Where Are Filter Bags Used?
Filter bags are used across industries where removal of suspended solids, process contaminants or particulate matter is important.
Key Industrial Applications
- Water Treatment: Pre-filtration and process-water filtration to reduce suspended particles and protect downstream equipment.
- Refineries and Oil & Gas: Filtration of process fluids and selected hydrocarbon-related streams where compatible filter media are required.
- Mining: Filtration of process liquids containing suspended solids and particulate contamination.
- Pulp & Paper: Process-liquid filtration where fibers, solids and contaminants need to be controlled.
- Chemical Industry: Filtration of compatible acids, chemicals, solvents and process liquids.
- Textile Industry: Process-fluid filtration and protection of equipment from particulate contamination.
- Power Plants: Filtration applications for process water, cooling systems and other compatible fluid streams.
- Dye & Intermediates: Filtration of process liquids where particulate removal is required.
- Edible Oils: Filtration of oil streams to reduce suspended particles and improve process cleanliness.
- Automobiles: Filtration of industrial fluids, coolants, paints and process liquids.
Other applicable sectors include petrochemicals, paints, inks, aeronautics, cement, fertilizers, bio-pharma, ceramics, sugar, defence and marine industries.
Aris Filtration identifies oil & gas, textiles, mines and minerals, cement, electronics and water-treatment-related customers among its industrial markets.
What Are the Benefits of Industrial Filter Bags?
The right filter bag can provide several operational advantages:
- High flow filtration capability
- Low pressure drop when correctly selected
- High dirt-holding capacity
- Efficient particulate removal
- Easy installation and replacement
- Multiple media choices
- Wide range of micron ratings
- Compatibility with different industrial fluids
- Customizable dimensions and fittings
- Suitable for high-solids and high-viscosity liquid applications
Aris Filtration specifically lists low pressure drop, high flow rate, high efficiency, chemical compatibility, easy installation and high dust-holding capacity among the benefits of its liquid filter bags.
How Do You Select the Right Filter Bag?
Choosing a filter bag only by micron rating can result in poor filtration performance. The complete operating environment should be considered.
Filter Bag Selection Checklist
| Selection Factor | Why It Matters |
|---|---|
| Fluid Type | Determines media compatibility |
| Micron Rating | Defines the target particle size |
| Flow Rate | Influences required filtration area |
| Temperature | Determines suitable media and construction |
| Pressure | Helps determine suitable bag and housing |
| Chemical Composition | Prevents media degradation |
