Floor inlet DN40/50 horizontal with connection flange, water siphon and stainless steel cap 121x121mm with grate HL510N-3000

Roof inlets – reliable drainage for terraces and balconies

This roof inlet with a connection flange is an optimal solution for draining water from terraces, balconies and other surfaces exposed to precipitation. Designed for easy installation and tightness, it ensures effective water drainage, minimizing the risk of leaks and structural damage. Equipped with a water trap, it prevents unpleasant odors from entering the building.

Construction and functionality

The inlet is characterized by a solid construction made of high-quality materials – polypropylene (PE) and high-grade steel (V2A/V4A). The inlet flange allows for a tight connection with the waterproofing layer, which is crucial for the proper functioning of the entire system. The adjustable height of the top in the range of 10-80mm allows for adaptation to differences in the thickness of the floor layers. The "Klick-klack" locking system facilitates the removal and cleaning of the grate. Water flow at a level of 0.55 l/s at a head of 20mm and 0.40 l/s at a head of 10mm guarantees quick and effective drainage of water even during heavy rainfall. Thermal resistance up to 85°C ensures durability and reliability in various operating conditions.

• Tightness: The connection flange in combination with the HL83 sealing kit ensures a completely tight connection with the waterproofing. This is crucial to avoid problems with leaks and moisture.
• Installation flexibility: Adjustable height of the top (10-80mm) allows adaptation to different floor layer arrangements, which facilitates installation and minimizes the need for additional modifications.
• Efficiency: A flow rate of 0.55 l/s ensures rapid water drainage, even during heavy downpours.
• Durability: The use of materials such as polypropylene and high-grade steel guarantees corrosion resistance and long-term use.
• Hygiene: The water trap effectively blocks access to unpleasant odors from the sewer into the building.
• Easy maintenance: The "Klick-klack" system allows for quick and convenient removal of the grate for cleaning or maintenance.

Application and compatibility

This inlet finds wide application in both residential and commercial construction – it is ideal for terraces, balconies, flat roofs and other places requiring effective drainage. The possibility of using additional elements (straight and flange extensions HL340N, HL85N, HL85NC, HL85NH) allows adaptation of the drainage to the specific needs of a given project. Load class L - 1.5 t ensures safe use even in places with high pedestrian traffic.
