Replacement Filter Bags for Liquid Filtration
Replacement liquid filter bags for industrial bag filter vessels, available in felt, mesh, extended life, high-efficiency and pleated media options.
Monarch Asia Pacific supplies filter bags for process water, chemicals, coatings, resins, food and beverage, wastewater and general industrial liquid filtration applications. We can assist with media selection, micron rating, bag size, seal type, chemical compatibility and replacement options for existing bag filter housings.
Filter bags are the replaceable filtration media used inside compatible bag filter vessels. They capture suspended solids as liquid passes through the bag, helping improve liquid cleanliness, protect downstream equipment and support reliable process operation.
The correct filter bag depends on the fluid, particle size, solids loading, operating temperature, chemical compatibility, flow rate and the level of removal efficiency required. For many applications, a standard nominal-rated felt bag is suitable. Other applications may require mesh, extended life, high-efficiency or pleated media.
Monarch Asia Pacific supplies filter bags for new filtration systems and replacement requirements, including options suitable for many industry-standard bag filter housings.
In a bag filter vessel, liquid is directed into the filter bag while the bag is supported by a perforated basket. The filter media captures suspended solids either on the surface of the material or within the depth of the media, depending on the bag construction.
Once the filter bag becomes loaded with retained solids, the pressure drop across the vessel increases and the bag is replaced. Choosing the right media and micron rating helps balance filtration performance, bag life and pressure drop.
Select from economical felt bags, mesh bags, extended life bags, high removal efficiency bags and pleated media options.
Economical nominal-rated filter bags for general liquid filtration applications where practical solids removal and low operating cost are required.
Mesh-style filter bags for applications requiring defined openings, coarse particle removal or lower resistance media.
Increased dirt-holding filter bags designed to provide longer service life than standard nominal-rated felt bags in suitable applications.
Filter bags selected where a higher level of particle retention is required at a nominated micron size.
Higher surface area filter bag options for applications where increased media area is beneficial within a standard bag filter vessel.
Assistance with matching the correct bag size, media, micron rating, ring style and material compatibility to your vessel and process.
The correct filter bag type depends on required particle removal, dirt loading, bag life, fluid compatibility and pressure drop.
| Filter Bag Type | Removal Size Range | Typical Selection Reason |
|---|---|---|
| Standard Felt Bags | 1 to 200 micron nominal | Economical general-purpose filtration for many industrial liquids. |
| Nylon Monofilament | 25 to 1250 micron | Mesh filtration where defined openings or coarse particle removal are required. |
| Extended Life Bags | 1 to 100 micron nominal | Longer service life and reduced changeout frequency in suitable applications. |
| High Removal Efficiency Bags | 0.2, 0.6, 1, 5, 10 and 25 micron absolute ratings | Improved particle retention at nominated micron ratings. |
| Pleated Media - Nominal | 1, 5, 10, 25, 50, 100 and 200 micron | Higher media area with nominal filtration performance. |
| Pleated Media - Absolute | 1, 5, 10 and 25 micron | Higher surface area with absolute-rated filtration options. |
Filter bag ratings can be described in different ways. A nominal micron rating is a general guide to particle removal and is commonly used for economical felt bags and many general-purpose filtration applications.
Absolute-rated or high removal efficiency filter bags are selected where the application requires more controlled particle retention at a nominated micron size. These bags may provide improved removal performance but can also create higher pressure drop and may require more careful sizing.
For critical applications, filter bag selection should consider the required removal efficiency, operating conditions and acceptable changeout frequency rather than relying on micron rating alone.
Filter bags are available to suit many industry-standard bag filter housings. When replacing bags in an existing vessel, it is important to confirm the bag size, ring type, material, micron rating and vessel sealing arrangement.
Many industrial bag filter vessels use common Size 01, Size 02, Size 03 or Size 04 bags, but variations can occur between brands and vessel designs. Monarch can assist with identifying suitable replacement options when bag or vessel details are available.
Filter bags are used across many industrial liquid filtration applications where suspended solids need to be removed from compatible liquids.
