Compliant with DWA-A 102 and BWK A 3 standards
Technical regulations such as DWA-A 102 and BWK A 3 place high demands on the retention of the finest fractions ( AFS63 ). While complex technical systems are often associated with high investment costs, our 70 µm fine filter bag offers an economical and technically feasible solution.
The installation takes place directly in the dirt collection bucket – without any costly modifications or infrastructural interventions.
Two-layer system for maximum operational reliability
The filter bag consists of two layers of polypropylene needle felt . This construction combines high water permeability with reliable retention of the finest particles down to 70 µm . The system is optimized for heavy rainfall events and withstands abrasive stresses from sand and tire wear.
Your advantages at a glance
- Highly efficient: Retention of the finest particles (nominal 70 µm) at high flow rates.

FAQ – Microplastic filter bag for street and yard drains
Frequently asked questions about microplastic filtration in street drains and debris buckets
The microplastic filter bag for street and yard drains (70 µm) was specially developed for the decentralized treatment of rainwater. It enables effective filtration of microplastics, tire abrasion, and fine particles directly in the debris collection bucket – without costly modifications to existing drainage systems.
What pollutants can the microplastic filter bag retain?
This significantly improves the quality of the drained rainwater, especially in the case of streets and courtyards.
Where is a microplastic filter bag used?
Typical areas of application include municipal roads, commercial yards, industrial areas or parking lots.
Does the filter bag support compliance with DWA-A 102?
By retaining fine solids, the proportion of filterable substances is reduced, which plays an important role in rainwater treatment.
How is the microplastic filter bag installed?
Retrofitting is possible without structural changes, allowing existing systems to be upgraded quickly.
How often does a microplastic filter bag need to be changed?
Regular inspection as part of routine shaft maintenance is usually sufficient.
