Roof inlet body DN75 with vertical outlet with sealing flange, siphon and stainless steel insert HL317KN

Universal ceiling drain DN75 – reliable water drainage

This ceiling drain body, with a diameter of DN75 and a vertical outlet, is a solid solution for draining water from ceiling surfaces. Made of high-quality materials, combined with a stainless steel insert, guarantees durability and corrosion resistance. Designed for both new installations and modernization of existing systems.

Design and application

The drain body features a sealing flange that allows for a tight connection with the waterproofing layer – particularly important when using HL84 series insulation kits. The siphon prevents unpleasant odors and backflow of air from the sewer. The vertical outlet facilitates integration with existing hydraulic infrastructure. The stainless steel insert ensures long-term reliability and ease of cleaning.

A flow rate of 1.6 l/s ensures effective water drainage even during heavy rainfall. Additionally, thermal resistance up to 95°C allows for use in areas exposed to higher temperatures – e.g. near heating devices or hot domestic water. The possibility of expanding with elements from the HL350 series and caps with grates HL66 and HL67 allows you to adapt the drain to specific project requirements and room aesthetics.

Key advantages

• Tightness: The sealing flange ensures the integrity of the waterproofing layer, minimizing the risk of leaks and structural damage.
• Durability: The stainless steel insert guarantees corrosion resistance and the longevity of the element, even in difficult operating conditions.
• Efficiency: A flow rate of 1.6 l/s effectively drains water, preventing flooding of the ceiling surface.
• Versatility: The ability to expand with additional elements (HL350, HL66, HL67 series) allows you to adapt the drain to different ceiling layer layouts and individual aesthetic preferences.
• Thermal resistance: Withstands temperatures up to 95°C, which increases the range of product applications.
• Siphoning: Prevents the return of unpleasant odors from the sewer.
