Efficient rainwater drainage from the roof

This roof inlet, part of the QuickStream (QS) system by WAVIN, is a solution designed for vacuum-based rainwater drainage. Its construction ensures efficient and reliable operation, and additional elements increase functionality and durability. The QuickStream system is not only efficient water drainage but also maintenance-free self-cleaning, which translates into long-term installation efficiency.

Design and application

The QS-M-75/260mm inlet is designed for installation on roofs of various structures. Made of durable stainless steel, the outlet guarantees corrosion resistance and longevity. A plastic spigot allows for easy and tight connection to the rest of the installation by welding or soldering. An additional gravel guard prevents debris from entering the system, protecting it from clogging and ensuring continuous operation. The inlet has a vertical outlet, which optimizes water flow.
