The Air Intake Pop Vent provides fresh outdoor air directly into air ducts, attics or buildings.

The Air Intake Pop Vent is ideal for maintaining proper attic ventilation. Our line of intake roof vents allows your exhaust vents to work efficiently by bringing in fresh air. These intake roof vents are maintenance-free and UL certified; in other words, tested to withstand wind pressure speeds up to 200 mph. They are constructed of durable rust-free aluminum and we offer powder coating to match vents to your roof.

The Pop Vent has vertical louvers that prevent rain and snow from entering. These louvers also keep out insects and animals which allows maximum fresh air supply without resistance. This attic vent is suitable for both commercial and residential applications. AVP offers an array of sizes to fit all ventilation needs. The vent head is removable which, as a result, allows for easy access for inspections or duct maintenance. The Pop Vent roof louver with Curb Mount Flange arrives ready for installation directly onto Roof Curbs. You can make your own roof curbs on-site, or select one of our aluminum Roof Curbs. Selecting one of our roof curbs insures that your vent will fit perfectly.

The diameter size of all roof vents determines the Net Free Area, also known as the "NFA". NFA is the measured amount of opening each vent offers at each specific size. to be available for venting air through a specific vent size. The calculator below will find the overall number of vents needed to effectively ventilate the targeted attic space.

Once you have the area, pulldown to select the specific vent diameter to show the number of vents of that size which would ventilate the specified area with both 1/300 and 1/150 rule.

*Please note
The roof vent calculation values shown above are for the exhaust portion of the roof. The same amount of net free air inches is needed for air intake as well. Proper roof ventilation consists of 50% air exhaust and 50% air intake.
