Available from Studor Australia , Maxi-Vent air admittance valves assist with the protection of trap seals within the drainage system.
These valves can be used for individual venting stack systems for buildings up to 10 storeys, removing the need of vent pipes through the roof. If a building is higher than 10 levels, a Positive Air Pressure Attenuator (PAPA) will be necessary.
Maxi-Vent air admittance valves remove the need for roof penetrations and can be used alongside the Mini-Vent valve in order to vent the whole building without conventional vents.
Maxi-Vent air admittance valves are able to withstand temperatures of -20°C to +60°C when used in combination with the correct packaging.
