Valsir can supply a waste system with a 110 mm and 160 mm diameter ventilation branch.
This is the ideal solution in high-rise buildings where the simultaneous use factor of the sanitary appliances is high.
This innovative waste system guarantees excellent ventilation of the waste stack and branches on each floor, limiting pressure fluctuations in the system.
This system also offers significant advantages in terms of money savings thanks to the possibility of constructing single stacks (therefore without installing parallel ventilation) in one single diameter, either 110 mm or 160 mm with double the draining capacity as compared to systems with primary ventilation.
