Description

Air Admittance Valves (AAV's) consist of a one-way valve designed to allow air to enter the plumbing drainage system when a pressure less than atmospheric develops. The device closes and seals by gravity under zero (0) differential pressure (static condition) and under positive pressure. These devices prevent sewer gases from entering a building. The device consists of a hooded or shielded body which contains a movable sealing assembly which seats and seals air flow when closed and allows air to enter when open.

Temperature Range: These devices shall function at temperatures from -40.0°F to 150.0°F (-40.0°C to 65.6°C).

Rating: These devices shall, at a minimum, pass the required volume of air according to Table 1 at -1.0 inch (-25.4 mm) water column.
