Emergency roof inlet gravity vent DN75 vertical, heated at 230V with overflow with adjustable height 28-68mm and PP collar HL62.1FSAFE/7

Emergency roof drain DN75 – reliable protection against water

This vertical roof inlet, designed for emergency drainage systems, provides crucial protection for the building against the effects of heavy rainfall. Its design is based on the principle of gravity drainage, activating in situations where the main roof drainage system cannot cope with excess water. It is important to remember that the emergency system should be a separate installation, not connected to the main roof drainage system.

Design and functionality

The inlet is made of high-quality polypropylene (PP) and equipped with a flange to facilitate installation and ensure a tight connection. Its design also includes an adjustable overflow height – in the range of 28 to 68 mm – which allows for precise adjustment to specific installation conditions and ensures optimal operation regardless of the water level. In addition, the inlet has a built-in self-regulating heating set powered by 230V, which prevents water from freezing in winter and ensures continuous system functionality. The use of a 180 mm diameter grate effectively stops larger debris, such as leaves or branches, protecting the installation from clogging.

Application and benefits

This roof inlet is primarily used in buildings with large roof areas, where the risk of overloading the drainage system is increased. Its installation is an investment in building safety and minimizes the risk of damage caused by water.
