Drain Basket B1 Retention System for Plastic Pellets – 70 µm Complete Set
Standards-Compliant Pellet Retention for Shallow Road Drains (DIN 4052)
Industrial outdoor areas with limited construction depth often use shallow catch basins. Our drain basket set B1 with a 70 µm micron rating is built exactly for these requirements. It lets industrial operators retrofit their drainage in a legally compliant way under EU Regulation 2025/2365, without any structural changes to existing installations. This specialised plastic pellet retention system protects your site against microplastic emissions.
The system is designed for high-traffic paved areas in the plastics-processing industry. Wherever pellets or regrind are loaded, the B1 drain basket serves as the last mechanical barrier before the sewer and is a key component for Operation Clean Sweep audits. It offers maximum security particularly in Transport & Logistics and Chemicals & Raw Materials.
Built for Shallow Installation Depths
Model B1, built to DIN 4052, is used wherever site conditions don't allow for a deep shaft. It's a proven component for infrastructure projects in Civil Engineering & Landscaping as well as Energy & the Environment:
- Shallow road drains on logistics and loading areas
- Car park drainage in industrial settings
- Access roads to silo systems
- Drainage of yard areas with limited shaft depth
No Bypass Risk Thanks to Winkler Fixing Technology
Conventional filter solutions often let particles pass around the edge. Our B1 system eliminates this risk with a mechanical forced-flow design for the water:
- Dimensionally stable design: The 70 µm fabric is engineered to make full use of the B1 bucket's shallow shape.
- Precision-fit filter collar: The filter fits over the rim of the galvanised bucket, creating a flush sealing surface.
- Secured with a drawstring: An industrial drawstring holds the filter permanently in place. Since we don't use an emergency overflow, the protective function stays 100% intact even during sudden heavy inflow (heavy rainfall).
