4000 Series 1,600 CFM Aluminum Roof Mount Power Attic Ventilators

Quick Overview

Model CX4000AA, VXSVRAA. Unit available in mill, black, brown, and weathered grey.

4000 Series Power Attic Vents are built for ventilating residential attic spaces up to 2,400 sq. ft. Our low profile aluminum dome is aesthetically pleasing on the roofline, withstands impacting wind, debris, and hail, and has a galvanized steel mesh screen to protect against insects, birds, and rodents. Install is straightforward and requires no special tools to complete. This roof mount vent is designed to ventilate hot air from the attic and pull in cooler air through under eave or soffit vents, prolonging the life of composite roof shingles, helping to prevent weather-induced home deterioration, and making living areas more comfortable. Swap your pre-wired thermostat for a thermostat/humidistat combo (XXDUOSTAT) or add a rain guard (XXRAINGUARD) for installs on steeper roof pitches.
