Pre-Filters for Infiltration Systems – Clean Inflow for Long-Lasting Performance
An effective pre-filter reliably protects your infiltration system from leaves, sand, and coarse debris. This helps keep infiltration trenches, soakaway crates, and infiltration tanks functioning efficiently over the long term while preventing blockages and reducing maintenance requirements.
GreenLife rainwater pre-filters are supplied ready for connection, manufactured from recyclable plastic, and designed for low-maintenance operation. They can be easily integrated into both new and existing rainwater management systems.
Ideal for use alongside rainwater tanks and cisterns, these filters ensure that pre-cleaned rainwater is discharged into the ground in a controlled manner. Protect the efficiency and longevity of your infiltration system with the right filtration technology.
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 waterEasy maintenance and quick cleaningDurable, walkable plastic cover includedEnvironmentally friendly & fully recyclableUV-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 DetailsTwo pre-assembled DN 110 connections with rubber lip sealsInlet and outlet for standard KG pipeInspection opening Ø 400 mmCuttable shaft with marking groovesMaterial: Polyethylene (PE), free of harmful substances, chemically inertWalkable 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 & QualityOur 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.

Pre-filter infiltration "EASY PRO"
Durable rainwater pre-filter with coarse debris basket – pre-assembled, low-maintenance, long-lasting The “Easy Pro” rainwater pre-filter is the reliable solution for pre-filtering rainwater before it enters your cistern or infiltration system. With two pre-assembled DN100 connections and a high-quality, walkable cover, this pre-filter offers an optimal combination of functionality, safety, and design. Thanks to the coarse debris filter basket installed in the shaft, coarse contaminants are efficiently retained. The filtered rainwater then flows cleanly for further use or infiltration into the ground. The filter is easily accessible, particularly easy to maintain, and ideally suited for installation in the ground. Product benefits at a glance:Ready to connect, pre-assembled & ready for immediate useCoarse debris filter basket for clean rainwaterDurable, slip-resistant plastic cover (load capacity up to 200 kg), child-proof screw-onuniversally applicable for cisterns or infiltration systemsTwo DN100 connections (lip seals pre-installed)Environmentally friendly: made from partially recycled PE, fully recyclableEasy to clean – ideal for areas with heavy leaf fall Application This pre-filter is ideally suited for use in infiltration systems, for example in combination with infiltration trenches, infiltration cubes, or infiltration blocks. It can also be installed upstream of a cistern to effectively remove coarse contaminants from incoming rainwater. Technical Data & NotesMaterial: durable, UV-resistant plastic (PE)Cover: walkable, slip-resistant, Ø 600 mmCleaning opening: easily accessiblePossible connection size: DN 110Symbolism: Cover design featuring the “Flower of Life” – slip-resistant & decorative Material & Quality The “Easy Pro” pre-filter is made of durable, eco-friendly polyethylene (PE)—an ideal material for use in rainwater management. PE is not only durable and shatter-resistant, but also fully recyclable, free of harmful substances, and chemically inert. This ensures that the quality of the filtered rainwater remains unaltered. Thanks to its high-quality construction, the filter is particularly easy to install and maintain. It is manufactured in a resource-efficient manner, partly using recycled plastic. Compared to pre-filters made of other materials, PE offers better recyclability, lower weight, and easier handling—both during installation and ongoing operation. Installation and Maintenance Instructions The filter should be embedded in a sand bed in a horizontal position and compacted. (An inclined position can impair function.) The shaft can be shortened and adapted to local conditions. For cleaning, we recommend regularly rinsing the filter basket with a garden hose depending on the amount of fallen leaves.

Two variants – the right fit for your project:Connection size selectable: DN 150 or DN 200 Includes inlet flow regulator, dome chamber, and child-safe cover Versatile, robust, well-designed – advantages at a glanceCombined chamber for sedimentation & filtrationfor rainwater from impervious surfaces up to approximately 1,000 m²Reliable protection against sand, leaves, oil, and suspended solidsEasy to maintain thanks to an easily accessible filter moduleSturdy, durable, and eco-friendly: made from recyclable PENo height difference between inlet and outletWalkable, optionally suitable for car/truck traffic (accessories sold separately)Decorative, slip-resistant cover featuring the “Flower of Life”Flexible installation thanks to stepless dome adjustment How the rainwater filter shaft works This product was developed for non-hazardous or low-pollutant stormwater runoff. 1. Inlet calming: The inflowing rainwater is slowed down by the inlet calming device. 2. Sedimentation: Coarse particles (e.g., sand, silt) settle in the spacious sedimentation chamber. 3. Filtration in the submerged pipe: Suspended solids, fine particles, fats, and oils are retained before the water enters the cistern or infiltration system. 4. Downstream system protected: Ideal for rainwater harvesting or safe infiltration. Material & Quality The rainwater filter shaft is made of high-quality, UV-stable polyethylene (PE)—it is shatterproof, durable, and 100% recyclable. The sustainable material is chemically inert and therefore ideally suited to ensuring long-term water quality. The shaft is fully pre-assembled and ready for immediate use. Installation & Maintenance The filter shaft (rainwater) is placed horizontally in a sand bed, filled in layer by layer, and compacted. The extendable leveling dome allows for easy adjustment to the ground level. Maintenance of the filter system is conveniently carried out via the inspection opening in the dome.
