LORO-X Series 43 model DUOFLUX double pipe DN 70 with weir

The new LORO-X DUOFLUX Attika-Direkt main-emergency-combination drains with weir on the right or left side DN 70/DN 70 with adhesive flange for the direct installation in the edge of the parapet roof combine the main drainage consisting of downpipe and rain standpipe with the emergency drainage as spout overflow with only one drain.

They enable the architect to design the double pipe on the facade. If the spout for the emergency drainage shall be arranged in flow direction, e.g. left of the collector box for the main drainage, the drain main drainage gravity flow with weir on the left side should be selected.

Advantages:

• only one drain for the main and emergency drainage
• discharge rate and water height compliant to the roof drainage standard:
- main drainage with gravity flow DN 70, discharge rate 2.2 l/s at a water height of 35 mm
- emergency drainage with gravity flow DN 70, discharge rate 3.4 l/s at a water height of 75 mm
