Harmer AV 90 degree Screw roof outlet
Anti-vortex.
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 90 degree screw roof outlet is for flat roof structures using in situ cast concrete, timber or lightweight metal deck construction. It directly connects to cast iron, HDPE and PVC pipework by means of a Harmer Roof screw threaded adaptor and appropriate coupling.
