Description

Alumasc Harmer Roof AV is an economic, general purpose range of outlets that provides anti-vortex performance. Harmer Roof AV incorporates a patented baffle within the grating to prevent water swirl and air entrapment, enabling the outlet to drain at 90% of its pipe capacity.

The Harmer AV Multi Gulley roof outlet is designed to provide multi-directional drainage. Rotated on site, the interchangeable spigot pipe allows for any angled outflow from vertical to horizontal. It directly connects to PVC O-ring socketed pipe or to cast iron and HDPE pipework by means of a suitable coupling.
