Controflow Vertical Roof Outlet Flow Control and Overflow Chamber


Applications – blue and green roofs.

A universal combined flow control and overflow chamber for use on blue and green roofs with vertical outlets. The roof outlet chamber can be easily installed, and is ideal for restricting flows from blue/green roofs, without interfering with existing roof outlets. Each chamber is designed to limit the flow through an orifice at the required discharge rate, and has an integral debris filter and an unrestricted overflow through a vertical outlet. Supplied complete with light duty cover. The control chamber should be located at the edge of the roof in the pebble perimeter strip to protect the inlet.

Key Points:

  • Integral debris filter
  • Universal flow control outlet
  • Combined flow control and overflow
