Roof inlet gravity DrainBox DN125 vertical, with bituminous collar d500mm, heated (10-30W/230V) HL63.1H/2

Gravity roof drain DrainBox is an effective solution for draining water from flat roofs. The construction based on a corrugated sheet ensures durability and stability, and the adjustable height (100-160mm) makes it easy to adapt to specific installation conditions. Designed for spigot connections DN125 or HDPE welded systems, providing flexibility in choosing the remaining installation elements.

This model features a built-in, self-regulating heating set (10-30W/230V) that prevents ice formation and ensures continuous operation of the drainage system even in harsh weather conditions. A bituminous jacket with a diameter of 500mm guarantees a tight connection with the roof insulation, minimizing the risk of leaks. A flow rate of 12.2 l/s allows for efficient drainage of large amounts of water, which is particularly important during heavy rainfall.

• Efficient flow: 12.2 liters of water per second ensures quick drainage of water from the roof.
• Freeze protection: Built-in heating system (10-30W/230V) eliminates the problem of ice formation and blockages in the drain.
• Tightness: Bituminous jacket with a diameter of 500mm provides a reliable seal for the connection with the roof insulation.
• Versatility: Compatible with spigot connections DN125 and HDPE welded systems.
• Height adjustment: Adjustable housing height (100-160mm) facilitates installation and adaptation to the specifics of the roof.
• Durable construction: Made of high-quality PP plastic, resistant to weather conditions and mechanical damage. The Laubfangkorb drain grid with a diameter of 145mm prevents leaves and other debris from entering the water drainage system.

The weight of the drain itself is about 3.73 kg, which makes it easy to transport and install. The DrainBox design has been thought out in terms of easy assembly and service – both for professionals and DIY enthusiasts.
