About Studor 20342 Maxi-Vent Air Admittance Valve With
Product Description The Studor Maxi-Vent Air Admittance Valve (AAV) is an accepted alternative to replace all forms of conventional stack venting, utilizing 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. Fits 3- or 4-inch connections. Dimensions: 5.25-inch vent height x 4.875-inch vent diameter. Rubber construction with a temperature Rating of -40 to 150 deg F. From the Manufacturer This advanced AAV protects the trap seals in the drainage system by allowing the intake of air, so a soil pipe can maintain the right level of pressure within the drainage system.
