Retrofit Filter for Plastic Granules – 70 µm (Available Individually)

Economical & Sustainable Retrofitting in accordance with EU Regulation 2025/2365

Existing drainage systems do not need to be completely replaced to meet modern environmental requirements. Our retrofit filter with 70 µm filter fineness enables industrial companies to cost-effectively upgrade existing gully pots and catch basins to the standard of EU Regulation 2025/2365. As the core component of our specialized retention systems for plastic granules, we offer this high-performance filter individually to provide you with maximum flexibility for maintaining and equipping your plant premises.

This replacement filter is the ideal solution for companies that want to implement technical retention measures as part of Operation Clean Sweep and continue to use existing resources such as galvanized gully pots according to DIN 4052. It stops plastic pellets and fine abrasion directly where they originate. Especially in sensitive areas of the Chemicals & Raw Materials and Energy & Environment industries, this retrofit is a central component of environmental protection.

Focus on Flexibility: Individually Instead of in Packs

We have adapted our offering to meet your actual industrial needs:

  • Available individually: Order exactly the quantity you need for your current replacement cycle.
  • Universal fit: Available for all common bucket sizes from A4 to yard buckets.
  • Cost reduction: The stable metal buckets are retained – only the filter medium is replaced.
  • Sustainability: Less material usage through targeted replacement of the wear component, ideal for requirements in Transport & Logistics.

Secure Sealing through the Winkler Principle

A retrofit filter is only effective if it seals absolutely tightly. Our system prevents the dreaded "gush-through" of granules past the bucket wall:

  1. Integrated collar: The 70 µm fabric features a reinforced collar that is simply pulled over the rim of your existing bucket.
  2. Mechanical fixation: A robust, industrial drawstring secures the filter to the bucket body. This guarantees forced passage of water through the fabric.
  3. No bypass: By eliminating an emergency overflow, the retention function is 100% maintained – a decisive advantage for your legally compliant site security in Civil Engineering & Landscaping.

Comparison of Retention System Models

When ordering the retrofit filter, simply select the size that matches your existing bucket type:

Model Application Area Bucket Type (DIN 4052) Special Feature

FAQ – Retrofit filter for granule retention 70 µm

Important information on replacing and retrofitting your granulate filter systems.

Can I use the retrofit filter in any slotted bucket?

Our retrofit filters are designed to fit the standard dimensions of slotted buckets according to DIN 4052 (A4, B1, C3, D1) as well as common yard buckets. As long as your existing bucket complies with these standards, our 70 µm filter can be easily retrofitted using the collar and drawstring system.

Why is the filter offered individually and not only in a set?

We want to offer industrial companies maximum flexibility. Often, the wear and tear at different drainage points on a factory site varies greatly. By ordering individual items, you can replace exactly those filters that show wear during inspection, without building up unnecessary stock.

How long does a 70 µm retrofit filter last in industrial use?

The service life depends heavily on mechanical stress (sediment load) and cleaning frequency. Since the fabric consists of a high-strength and chemical-resistant polymer, it is designed for several years of use. We recommend a monthly visual inspection to ensure the integrity of the fabric.

Does the retrofit filter meet EU Regulation 2025/2365?

Yes. The regulation requires effective technical measures to prevent pellet loss. With a filter fineness of 70 µm and bypass-free installation, you meet the high demands for retention security and make a significant contribution to water protection.

Is special tooling required for filter installation?

No. Installation is tool-free. The filter is placed over the edge of the bucket, and the integrated drawstring is tightened and secured by hand or with simple pliers. The system is designed for quick replacement by on-site maintenance personnel.
