Filter bag for sludge dewatering, special size – F-BAG GE Vernova
Customized sludge dewatering for special installation situations
The WINKLER GE Vernova filter bag for sludge dewatering in a special size was developed specifically for applications where standard sizes cannot be used. As a gravity filter bag, it enables reliable separation of solids and liquids even in systems with limited height or unusual dimensions.
This special size is based on the proven F-BAG filter bag technology and combines robust industrial quality with a precision-fit design. This makes the filter bag particularly suitable for existing systems where filter bags must fit exactly into existing shafts or containers.
The filter material made of polypropylene needle felt is mechanically durable as well as acid and alkali resistant and therefore suitable for many industrial process waters.
Typical areas of application
The special size is particularly suitable for applications with fixed installation dimensions or special system concepts:
- Industrial plants with predefined shaft dimensions
- Power plants and energy facilities
- Car washes with special filter bag holders
- Recycling and process water plants
Thanks to its adapted design, the filter bag can be used where standard sizes would not fit or would only function to a limited extent.
Customized solutions like these are in demand in all highly specialized industries . We manufacture special sizes for power plants in the energy and environmental sector, for individual filtration requirements in the chemical industry , and for civil engineering projects. We also offer special dimensions for the construction sector , agriculture , and complex requirements in transportation and logistics .
How gravity filtration works
Dewatering is carried out using the 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.
The flat design allows for use in systems with limited height without compromising dewatering performance. This makes sludge dewatering easy to implement even in existing systems.
The filter bag is particularly suitable for businesses that need a reliable and perfectly fitting solution for their drainage processes.
Your advantages with special sizes
This special size combines the proven filter bag technology of the F-BAG series with a precisely adapted design. This allows existing systems to continue to be used without the need for extensive modifications.

Which filter bag is the right one? Size comparison of the F-BAG series
In addition to custom sizes, various standard sizes are available. The choice depends on the amount of sludge, the installation situation, and the desired capacity.
| variant | Usable volume | Area of application | Typical application |
| F-BAG M | 0.125 m³ | Small batches | Mobile operations, maintenance work and smaller quantities of sludge. |
| 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 this special size, we also manufacture filter bags to individual dimensions . This allows existing systems to be used optimally without having to make costly modifications.
