Drain Basket A4 Retention System for Plastic Pellets – 70 µm Complete Set

Maximum Retention Security for Deep Road Drains Under EU Regulation 2025/2365

For main traffic areas and logistics zones with deep catch basins, the Drain Basket A4 with a 70 µm micron rating is the highest-performance option within our plastic pellet retention systems. This complete set was developed specifically to help industrial operators meet EU Regulation 2025/2365 in a legally compliant way. It offers maximum capture volume for plastic pellets and the finest abrasion directly at the point of surface drainage.

Thanks to its tall design (Form A per DIN 4052), this system is ideal for areas with high water volumes and potentially larger pellet emissions. It's an essential technical component for companies pursuing Operation Clean Sweep certification or looking to secure their environmental standards long-term.

Primary Use: High-Traffic Industrial and Logistics Areas

Model A4 is the standard for high-volume drainage systems on industrial sites, particularly in sectors such as Energy & the Environment or Chemicals & Raw Materials:

• Central loading zones for silo vehicles in Transport & Logistics.
• Main access roads and logistics routes in the plastics-processing industry.
• Large car parks and yard areas on industrial sites.
• Areas with deep road catch basins per DIN 4052, common in Civil Engineering & Landscaping.

Zero Emissions Through Mechanical Forced-Flow Design

A critical weak point of many filter systems is the bypass. Our A4 system prevents particles "slipping through" with a fully sealed design:

1. High filter volume: The dimensionally stable 70 µm fabric uses the full depth of the A4 bucket to ensure long service intervals.
2. Integrated collar: The fine filter fits directly over the bucket's rim, forming a physical barrier between the bucket wall and the shaft.
3. Secure fixing: A reinforced industrial drawstring holds the filter in position even under high water pressure. With no emergency overflow, every particle above 70 µm is reliably retained.
