Industrial Liquid Filtration Systems
Practical bag filter vessels, replacement filter bags and cleanable basket options for industrial liquid filtration applications.
Monarch Asia Pacific supplies bag filter systems for process water, chemical liquids, manufacturing fluids, coatings, resins and general industrial services. We can assist with vessel selection, filter bag compatibility, micron rating, material choice and practical installation requirements.
Bag filtration is one of the most widely used methods of liquid filtration because it is simple, scalable and cost-effective. A bag filter system normally consists of a pressure-rated vessel, a support basket and a replaceable filter bag. Liquid enters the vessel, passes through the filter bag and exits after suspended solids have been captured by the filter media.
The system can be configured for light-duty flows, high-volume process lines, chemical compatibility requirements or applications where operators need fast and straightforward filter bag changeout. Depending on the application, vessels may be stainless steel, non-metallic or custom fabricated.
Monarch Asia Pacific can support both new installations and replacement requirements, including vessels, filter bags, cleanable baskets, strainers, fabricated components and filtration skids.
In a typical bag filter vessel, contaminated liquid enters the housing and is directed into the filter bag. The filter bag is supported by a perforated basket so that the bag remains correctly positioned during operation.
As liquid passes through the filter bag, suspended particles are captured either on the surface of the media or within the depth of the material. The filtered liquid then exits the vessel and continues through the process line.
When the filter bag reaches its dirt-holding limit, it can be removed and replaced. In some applications, a cleanable stainless steel basket may be used instead of a disposable filter bag.
Bag filters are a practical choice where reliable solids removal, simple maintenance and flexible media selection are important.
Bag filter systems generally offer low capital cost, simple operation and practical replacement media for many liquid filtration duties.
The filter bag provides a useful filtration area and can hold a significant amount of retained solids when correctly sized.
Filter bags are normally quick to remove and replace, helping reduce maintenance time and simplify routine servicing.
Systems can be supplied as single-bag vessels, duplex arrangements, multi-bag housings or fabricated skid packages.
Filter bags are available in felt, mesh, high-efficiency and specialty materials to suit different fluids and particle retention requirements.
Monarch can assist with vessel selection, replacement bags, baskets, fabricated supports and application-specific filtration requirements.
Select from bag filter housings, replacement filter bags and cleanable basket options to suit your process.
Single bag filter housings for applications where one filter bag provides suitable flow capacity and dirt-holding volume.
Multi-bag vessels for higher flow rates, larger filtration area and longer service intervals in demanding process applications.
Corrosion-resistant non-metallic filter housings for compatible chemical, water treatment and industrial process liquids.
Replacement liquid filter bags in a range of materials, micron ratings, ring types and sizes for compatible bag filter vessels.
Cleanable perforated or mesh-lined baskets for applications where reusable filtration media is preferred. "Made in Australia"
Practical workshop support for fabricated frames, supports, skid arrangements and filtration-related modifications.
Bag filter housings can be selected to suit flow rate, operating pressure, temperature, chemical compatibility and connection requirements. Common vessel configurations include single-bag housings, multi-bag housings, duplex arrangements and fabricated skid packages.
Housing materials may include stainless steel or compatible non-metallic materials depending on the application. Connection options can include threaded, flanged, socket or fusion-style arrangements depending on the vessel type and process requirements.
| Common sizes | Industry-standard Size 01, 02, 03 and 04 bag housings |
|---|---|
| Configurations | Single-bag, multi-bag, duplex, skid and custom arrangements |
| Material options | Stainless steel, PP, GFPP, PVC, CPVC and selected custom materials |
| Connections | Threaded, flanged, socket or fusion-style options depending on vessel type |
Filter bags are available in different media types and micron ratings to suit the required particle removal performance. The correct filter bag should be selected based on the fluid, particle type, solids loading, temperature, chemical compatibility and allowable pressure drop.
Nominal-rated bags are commonly used for economical general-purpose filtration, while high-efficiency media may be selected where improved particle retention is required.
| Micron ratings | From fine filtration through to coarse particle removal, depending on media type |
|---|---|
| Common materials | Polyester, polypropylene, nylon, PTFE and specialty filter media |
| Seal options | Plastic ring, steel ring and sewn-in ring styles depending on bag type |
| Efficiency | Nominal and high-efficiency filter bag options available |
Flow rates vary depending on liquid viscosity, micron rating, solids loading and allowable pressure drop.
| Bag Size | Indicative Flow Rate | Approximate Bag Dimensions | Approximate Flow Area |
|---|---|---|---|
| Size 01 | 20,000 litres per hour | Ø178 mm × 420 mm | 0.24 m² |
| Size 02 | 40,000 litres per hour | Ø178 mm × 810 mm | 0.48 m² |
| Size 03 | 6,000 litres per hour | Ø102 mm × 230 mm | 0.08 m² |
| Size 04 | 12,000 litres per hour | Ø102 mm × 410 mm | 0.16 m² |
Filter bags are often described as either nominal-rated or high-efficiency media. A nominal rating is a general indication of the particle size range that the bag is expected to remove under certain conditions. Nominal ratings are useful for product selection, but they should not be treated as an exact or absolute particle removal guarantee.
High-efficiency filter bags are selected where improved particle retention is required. These bags may provide more consistent removal performance, but they can also create higher pressure drop and may require more careful sizing.
Correct bag filter selection starts with understanding the process. The vessel, bag size, media type and micron rating should be selected together so the system can handle the required flow without excessive pressure drop or short bag life.
A correctly sized system can reduce maintenance frequency, improve process reliability and help protect pumps, valves, spray nozzles, heat exchangers or other downstream equipment.
