Pre-filter for infiltration

Product information " Pre-filter for infiltration"

Reliable pre-filter for rainwater infiltration – for effective rainwater filtration 

Reliably protect your infiltration system from dirt and coarse particles – with our high-quality rainwater pre-filter. The pre-assembled filter chamber, made of durable, eco-friendly plastic, is the ideal solution for efficient and long-lasting rainwater infiltration. 

Your benefits at a glance:

  • Ready to connect & ready for immediate use (inlet & outlet DN 110)
  • Effective coarse debris filtration for clean water
  • Easy maintenance and quick cleaning
  • Durable, walkable plastic cover included
  • Environmentally friendly & fully recyclable
  • UV-resistant and opaque 

Product description 

The rainwater pre-filter impresses with its ease of use, long service life, and quick installation. Incoming rainwater is filtered through a coarse debris filter basket. Filterable solid particles such as leaves and sand remain in the basket, while the purified water then flows into the infiltration system. The filter unit is easily accessible and can be easily inspected and cleaned—ideal even in areas with heavy leaf fall. 

Technical Details

  • Two pre-assembled DN 110 connections with rubber lip seals
  • Inlet and outlet for standard KG pipe
  • Inspection opening Ø 400 mm
  • Cuttable shaft with marking grooves
  • Material: Polyethylene (PE), free of harmful substances, chemically inert
  • Walkable cover, child-proof screw-on 

Application 

This pre-filter is ideal for use in infiltration systems, e.g., in combination with infiltration trenches, infiltration cubes, or infiltration blocks. It can also be placed upstream of a cistern to treat incoming rainwater. 

Material, Manufacturing & Quality

Our rainwater pre-filter is made of polyethylene (PE)—a material ideally suited for rainwater products because it is environmentally friendly, free of harmful substances, and chemically inert, meaning it does not react with other substances. Thus, the quality of the rainwater is not negatively affected. 

Maintenance & Installation Instructions 

As with the installation of KG pipes, the rainwater filter must also be embedded in gravel and compacted evenly all around. Please ensure—using a spirit level, for example—that the filter is installed horizontally. 
The shaft can be cut to any length and easily adapted to local conditions. It features circumferential marking grooves that serve as a guide when cutting with a standard jigsaw. Depending on the amount of fallen leaves, the filter insert should be removed several times a year for cleaning and, if necessary, rinsed with a garden hose.

Entlüftung Wassertank
Aerator and vent with DN 100 emergency overflow

Vent and air release valves for safe pressure equalization & reliable emergency drainage The vent and air release valve with DN 100 emergency overflow ensures reliable air equalization in tanks, pipes, and soakaway systems and effectively protects the system against overpressure or underpressure. If the maximum water level is exceeded, for example during heavy rain, the component also acts as an emergency overflow for safe drainage. The vent is typically installed at the end of an infiltration system and is usually discreetly located outdoors, e.g., in a hedge or flower bed. To ensure that (rain)water can flow smoothly into the system, a controlled air outlet must be provided elsewhere. For this purpose, a DN 100 KG pipe is installed behind the system, which safely guides the air to the surface. The vent is the terminus of this line and is designed to reliably prevent the entry of animals. Product Features & Benefits at a Glance Pressure equalization during water withdrawal or supply – prevents damage caused by overpressure or underpressure Automatic venting and de-airing – ensures trouble-free system operation Integrated emergency overflow – protects against overfilling during heavy rain Standard DN 100 connection – compatible with common KG pipe systems Lightweight & durable – approx. 350 g, made of robust polypropylene Made in Germany – manufactured to high quality standards and DIN EN ISO 14001:2015 Typical applications Rainwater storage tanks & infiltration systems – for ventilation and emergency drainage Wastewater collection pits & infiltration systems in wastewater treatment plants – for pressure equalization and operational reliability Sustainability The product is made of durable, single-grade, and fully recyclable polypropylene. The material is long-lasting, free of harmful substances, environmentally friendly, and chemically inert – it has no impact on the environment. The production and recycling of this plastic are resource-efficient. Responsible use in line with the circular economy is a central component of our sustainable practices. Notes The vent should be inspected once or twice a year to ensure consistently reliable operation.
