Roof inlet gravity vent DN75/110 horizontal, with ring and leaf basket HL64

Gravity roof inlet – reliable flat roof drainage

This roof inlet, with a diameter of DN75/110, is a key element of the roof drainage system. Designed for gravity water drainage, it performs well in various roof configurations – from traditional, inverted and ventilated, to green roofs. Thanks to the possibility of using additional elements (supporting and drainage rings of the HL350 or HL65 series), it can be perfectly adapted to the specifics of a particular roof.

The inlet is characterized by a tight connection with the waterproofing layers, which guarantees long-term protection against leaks. Made of high-quality polypropylene (PP), it is resistant to corrosion and mechanical damage. The included leaf basket effectively prevents clogging of the drain with impurities, minimizing the need for frequent inspections and maintenance.

Versatile installation and adaptation to installations

Installation is simple and intuitive. The inlet allows for a DN75/110 socket connection or the use of a manufacturer's compensating socket for HDPE welded pipe systems. This provides flexibility in the selection of materials and installation methods, which will be appreciated by both professionals and those performing renovation work independently.

Using this inlet is not only protection of the building against moisture, but also an investment in the durability and reliability of the drainage system. A flow rate of 10.00 l/s for DN75 and 6.00 l/s for DN110 ensures effective water drainage even during heavy rainfall. A wide range of additional accessories allows for optimal drainage solutions for roofs with very diverse layer arrangements – this is a key feature for demanding architectural projects.
