Filter bag for sludge dewatering 0.8 m³ – F-BAG XL (gravity filter bag)
Flexible sludge dewatering for larger batches
The WINKLER F-BAG XL (0.8 m³) filter bag for sludge dewatering is an economical solution for the reliable separation of solids and liquids in industrial wastewater. As a gravity-fed filter bag , it enables mobile sludge dewatering without the need for technical equipment and can be used directly on site.
The F-BAG XL is particularly suitable for applications with regularly occurring sludge volumes, where smaller filter bags would require too frequent changes. Its larger volume of 0.8 m³ provides a sufficiently large filter surface area, ensuring uniform dewatering and supporting stable process flows.
The robust filter material made of polypropylene needle felt is resistant to acids and alkalis and is therefore suitable for many industrial process waters.
Typical areas of application
The filter bag is particularly suitable for applications where sludge needs to be dewatered directly at the source:
- Washing facilities for vehicles and machinery
- Concrete processing and concrete plants
- Recycling plants and construction sites
- Industrial process wastewater
The filter bag ensures that solids are reliably separated and that downstream systems or separators remain protected.
Designed for larger sludge volumes, this filter bag serves specialized applications . It is frequently used in agriculture and farming , but also in heavy construction and large-scale energy and environmental facilities. Companies in the chemical and raw materials , transportation and logistics , and civil engineering and landscaping sectors also rely on its capacity.
How gravity filtration works
Dewatering is carried out according to the simple principle of gravity filtration. The contaminated water is introduced into the filter bag, while the solids are retained in the filter material. The purified water can then be discharged in a controlled manner or reused.
Thanks to the large filter surface, the water flow remains stable and the filter bag can be used for a longer period of time before emptying becomes necessary.
The F-BAG XL is particularly well suited for applications where medium to large quantities of sludge are regularly generated and a reliable mobile solution is required.
Their advantages in practical use
The F-BAG XL combines high capacity with easy handling and is suitable for many typical applications in industry and trade. Thanks to its robust design, the filter bag can also be used safely with heavy sludge.
- Large usable volume: 0.8 m³ for larger batches.
- Robust design: Suitable for industrial applications.
- Chemically resistant: Acid and alkali resistant.
- Efficient drainage: High water permeability.
- Safe handling: Reinforced lifting loops make transport easier.
Which filter bag is the right one? Size comparison of the F-BAG series
The appropriate size depends primarily on your sludge volume, batch size, and the structural conditions. A comparison will help you quickly classify the different filter bag options:
| variant | Usable volume | Area of application | Typical application |
| F-BAG M | 0.125 m³ | Small batches | Short-term deployments or smaller amounts of mud in limited space. |
| F-BAG L | 0.5 m³ | Medium-sized volume flows | Regular drainage with a good balance between size and handling. |
| F-BAG XL | 0.8 m³ | Larger batches | For applications with higher sludge volumes and longer dewatering intervals. |
| F-BAG XXL | 1.25 m³ | Industrial use | Maximum capacity for large volume flows and heavy industrial sludge. |
| F-BAG Special Size (GE Vernova) | Custom size | Special installation situations | Custom-fit filter bags for shaft systems or special containers with limited height. |
In addition to standard sizes , custom-made filter bags are also available. Special sizes are particularly suitable for existing systems or special installation situations where standard dimensions do not fit.

FAQ – Filter bag 0.8 m³ for larger quantities of sludge
Frequently asked questions about sludge dewatering with large-volume filter bags
The 0.8 m³ filter bag is particularly suitable for applications with larger quantities of sludge, where smaller filter bags would require too frequent changes. The larger usable volume and filter surface area ensure stable dewatering processes. Here you will find answers to frequently asked questions about using filter bags for larger batches.
When is a filter bag with a capacity of 0.8 m³ useful?
This size is often used when medium filter bags fill up too quickly, but an industrial size is not yet required.
What advantages does a larger filter bag offer for sludge dewatering?
At the same time, the larger filter area ensures a uniform water flow and stable drainage performance.
How much sludge can a 0.8 m³ filter bag hold?
The actual amount depends on the solids content and the water content of the sludge.
Is the filter bag also suitable for heavy industrial sludge?
The reinforced lifting loops enable safe recovery even with heavier loads.
When should a larger filter bag be used instead of a 0.8 m³ one?
The larger capacity reduces change intervals and is particularly suitable for continuous industrial applications.
