This system is suitable in very high buildings (hotels, barracks, office blocks) and where the flow rate and factor of contemporary use are important.
It is economically viable for buildings with more the 7÷8 floors.
Our systems with 110 mm ventilation branches allow the connection of 45 apartments of equal size and up to 195 apartments of equal size with the 160 mm ventilation branch (for more details see the Valsir technical handbook “Waste systems inside the building”).
Allows an increase in the flow of the waste stacks of 45-55% as compared to a parallel or secondary ventilation system.
Significantly reduces pressure fluctuations inside the stack thanks to the special configuration of the ventilation branch.
Each ventilation branch is equipped with 6 connections that allow different attachment configurations of the sanitary fixtures.
The stacks can be created with 110 mm or 160 mm diameters depending on the dimensions of the ventilation branch used.
Up to 8 WCs can be connected to each ventilation branch.
A system with ventilation branches will drain greater flows than any other type of waste system. The UNI EN 12056-2 Stand indicates the maximum flow that a waste stack can drain in relation to the ventilation system adopted, it is therefore possible to compare them to the ventilation branch system.
