Series 79 RAINSTAR parapet drainage systems with siphonic flow

Discover the RAINSTAR Series 79 parapet drainage, which was specially developed for the drainage of flat roofs and parapet roofs with external downpipes and powerful siphonic flow in commercial and industrial buildings. The systems are characterized by their flow-optimized system shape, which ensures efficient and reliable drainage of rainwater.

Low-lying pipe

An outstanding feature of the Series 79 RAINSTAR parapet drains is the lowered pipe, which leads to an improved start of the siphonic flow. This innovative design ensures that the high discharge of the siphonic flow is achieved safely and at an early stage.

Upstand as an assembly aid in the parapet edge

Another advantage of this series is the 45 or 90 degree upstand, which serves as an assembly aid in the parapet edge. This makes installation easier and enables precise and stable fastening of the parapet drain. The upstand also contributes to improved sealing.

Main and emergency drain on one level

Another highlight of this series is the expansion of the program to include the parapet emergency drain for gravity flow. This emergency drain with weir (reservoir element) is installed at the same level as the main drains and thus ensures additional safety and drainage capacity in the event of increased water volume.

Advantages

• High drainage capacity due to siphonic flow
• Upstand as an installation aid in the parapet edge
• Sealing in just one level
• Emergency drains are installed in the same level as the main drains
