Studor Maxi-Vent

The Studor Maxi-Vent Air Admittance Valve (AAV) is an accepted alternative to replace all forms of conventional stack venting, utilising active air pressure control, allowing the air to enter the system at the point of need. The Maxi-Vent admits air under condition of reduced pressure in the discharge pipes and prevent water seals in traps from being drawn; thus contributing to the ventilation of the main drain to which the discharge stacks incorporating the Maxi-Vent are connected

• Screening on the inside and outside of the Maxi-Vent to protect the sealing membrane from foreign objects.
• Ability to divert condensation away from the sealing membrane.
• Prevents the release of foul air from the drainage system.
• Independently tested to verify operation from -40ºC.
