Series 79 RAINSTAR parapet drainage with gravity flow

Discover the Series 79 RAINSTAR parapet drainage, specifically developed for the drainage of flat roofs and parapet roofs with external downpipe and Silent gravity flow in residential and commercial buildings. The drains are characterized by their flow-optimized construction, which ensures efficient and reliable discharge of rainwater.

Lowered pipe

An outstanding feature of the Series 79 RAINSTAR parapet drains is the lowered pipe, which leads to a significant improvement in drainage performance during gravity flow. Through this innovative construction, rainwater is effectively and quickly discharged, contributing to optimal roof drainage.

Upstand as mounting aid in the parapet edge

Another advantage of this series is the upstand at 45 or 90 degrees, which serves as a mounting aid in the parapet edge. This facilitates installation and enables precise and stable attachment of the parapet drain. The upstand also contributes to improved sealing.

Main and emergency drain at the same level

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

Advantages

• High drainage capacity through lowered pipe
• Upstand as mounting aid in the parapet edge
• Sealing at only one level
• Emergency drains are installed at the same level as the main drains
