Adjustable off-center roof inlet DN50/75 with sealing flange and leaf basket HL80.3

Roof water drainage – reliable roof inlet DN50/75

This adjustable roof inlet, with a diameter of DN50/75, is a key element of the roof water drainage system. Its eccentric design allows for flexible adaptation to the roof layout, and the adjustable outflow angle within a range of 90 degrees ensures optimal performance regardless of conditions. The set includes a sealing flange and a leaf basket, which significantly simplifies installation and ensures long-term functionality.

The inlet is designed for gravity drainage of the roof and is characterized by a flow rate of 1.0 l/s, making it suitable for surfaces up to 33 m² with typical rainfall (300 l/(s·ha)). Made of durable PP/PE materials, it guarantees resistance to weather conditions and long service life.

Installation and versatility

A key advantage of this inlet is the possibility of a tight connection with the waterproofing layer thanks to a dedicated sealing kit from the HL83 series. This is important to ensure the integrity of the roof and prevent leaks. In addition, compatibility with simple and flanged extensions (HL340N, HL85N, HL85NH) and a drainage ring (HL180) allows you to adapt the drainage system to specific needs and the layout of the roof structure. For installers, this means greater design freedom and the ability to create an optimal solution for every roof.

It is worth mentioning the possibility of using the HL82 heating set, which prevents ice formation during the winter – especially important in regions with harsh climates. The leaf basket effectively stops debris, protecting the drainpipes from clogging and ensuring the continuous operation of the system throughout the year. This translates into less frequent inspections and lower maintenance costs.
