Roof inlet body DN50/75/110 with vertical outlet, sealing flange, siphon and bituminous jacket d 500mm HL317KH

Universal roof drain with bituminous collar

This roof drain body, with a diameter of DN50/75/110, is a key element in systems for draining water from flat surfaces. Designed for both new installations and modernization of existing ones, it provides a reliable and tight connection with the waterproofing layer. Its design with vertical outlet and siphon prevents unpleasant odors and ensures efficient water flow.

Tightness and durability in every detail

The drain body is equipped with a 500mm bituminous collar, which guarantees an excellent seal with the moisture insulation. This is particularly important on terraces, flat roofs and in rooms with increased hygiene requirements. The material of construction – polypropylene (PP) – is characterized by high chemical and mechanical resistance, ensuring long-term operation even in difficult conditions. Additionally, the product exhibits thermal resistance up to 95°C.

Performance and installation flexibility

Water flow at 1.8 l/s ensures rapid drainage of rainwater or wastewater, minimizing the risk of flooding. The drain design allows easy adaptation to different roof layer arrangements and completion with elements from the HL350 series (extensions) and HL66 and HL67 (gratings). This gives installers great freedom in designing and implementing even the most demanding investments. It is worth remembering the possibility of using it with an adjustable frame in the range of 20-70 mm and a frame with dimensions of 147 x 147 mm.
