Roof drain DN50/75 with articulated outlet and bituminous collar, siphon, and cast iron grating lid class L15 (1.5t) HL81.1GH

Roof drain DN50/75 with articulated outlet – reliable roof drainage

This roof drain, with a diameter of DN50/75, is a comprehensive solution for draining water from flat roofs. Equipped with an articulated outlet, water trap, and bituminous collar, it provides effective and tight drainage, minimizing the risk of leaks. The cast iron grate with a load class of L15 (1.5t) makes it an ideal choice for both residential and public buildings.

Design and functionality

A key element of this drain is the bituminous collar, which allows for a tight connection with the bituminous waterproofing layer. This avoids problems with water penetration under the roof covering. The adjustable outlet angle in the range of 90 degrees allows for adaptation to specific installation conditions and system layout. The water trap prevents unpleasant odors, and the adjustable grate height (in the range of 30-75mm) makes it easy to adapt to the thickness of the roof layers. A flow rate of 0.5 l/s ensures effective drainage even during heavy rainfall.

Application and compatibility

This drain is used in drainage systems for flat roofs of various designs. The possibility of expanding with additional elements – such as straight and collar extensions (HL340N, HL85N, HL85NC, HL85NH) – allows for adapting the drainage to the specific arrangement of the roof layers. Additionally, it can be equipped with a heating set HL82, which increases its functionality in difficult weather conditions. Thermal resistance up to 85°C guarantees its reliable operation even at high ambient temperatures. Load class A15 (1.5t) ensures safe use and resistance to mechanical damage.
