Sludge Dewatering Bag 0.125 m³ – F-BAG M (Gravity Filter Bag)
A Compact Solution for Small Sludge Volumes
The WINKLER sludge dewatering bag F-BAG M (0.125 m³) is the compact solution for reliably separating solids and liquids in industrial wastewater. As a gravity filter bag, it enables simple, mobile sludge dewatering with no technical plant required and can be used flexibly at different sites.
With a usable volume of 0.125 m³, the filter bag is particularly well suited to smaller batches, maintenance work or applications with limited space. The F-BAG M is quick to set up and easy to transport, making it especially suitable for mobile use.
The polypropylene needle-felt filter material is mechanically robust and resistant to acids and alkalis, making it suitable for a wide range of industrial process waters.
Typical Applications
The filter bag is particularly well suited to smaller dewatering tasks and mobile deployments:
- Maintenance and cleaning work
- Small washing systems and side streams
- Concrete processing with low sludge volumes
- Mobile use on construction sites
This compact filter bag proves its worth across a wide range of industries. It's particularly well suited to short-term use in construction or smaller side streams in agriculture. It's also a flexible choice for mobile service work in transport & logistics as well as in civil engineering and landscaping.
How Gravity Filtration Works
The principle behind it is simple: the sludge-water mixture flows into the filter bag under gravity alone. Solids stay trapped in the filter material while the water drains away in a controlled manner and can be reused.
Thanks to its compact design, the filter bag can be set up quickly and used flexibly. After dewatering, the sludge can simply be removed and disposed of properly.
The F-BAG M is particularly well suited to businesses that need a mobile solution for small sludge volumes or only dewater occasionally.
Your Benefits in Practical Use
The F-BAG M is designed for easy handling and flexible use. Its compact size makes the filter bag especially easy to transport and quick to deploy.
- Compact design: Ideal for limited space.
- High mobility: Easy to transport and ready to use quickly.
- Robust material: Suited to industrial applications.
- Chemically resistant: Copes well with acidic and alkaline process water.
- Efficient dewatering: The fabric lets water pass through freely.
Which Filter Bag Is Right for You? F-BAG Series Size Comparison
The right size depends mainly on your sludge volume, batch size and site conditions. This comparison helps you quickly identify the right filter bag variant:
| Variant | Usable volume | Application range | Typical use |
| F-BAG M | 0.125 m³ | Small batches | Mobile use, maintenance work and smaller sludge volumes. |
| F-BAG L | 0.5 m³ | Medium volume flows | Regular dewatering with a good balance of size and handling. |
| F-BAG XL | 0.8 m³ | Larger batches | For 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 Custom Size (GE Vernova) | Custom size | Special installation situations | Precision-fit filter bags for shaft systems or special containers with limited height. |
Alongside standard sizes, custom-made filter bags are also available. Bespoke sizes are especially well suited to existing plant or special installation situations where standard dimensions don't fit.
