Product Overview

Active Ventilation Products Keepa Vent will alleviate moisture in the winter and heat in the summer to extend the life of the roof and building structure. The Keepa Vent is best used for flat roof attic spaces as an exhaust roof vent or fresh air supply intake roof vent. Made of corrosion resistant aluminum, the Keepa Vent has a round concentric vent cap and standard 11 in. collar height, square flange and an inner louver wildlife guard. The vent cap is a manufactured one piece spun round aluminum cap that prevents rain and snow from entering the vent. The vent cap is removable to allow access for an easy rubber boot installation for membrane roofs. The 11 in. standard collar is excellent for locations that accumulate high levels of snow falls and the round design is aerodynamic to with stand wind speeds up to 200 mph. The Keepa Vent has proven to be an excellent and economical choice for a flat roof application.

I want to use this vent for a bathroom. The problem I have is that a regular 4 inch duct won't fit in this vent. Can you tell me how I can use this vent in a bathroom application?

Rated 1.0 out of 5 by 1 reviewer.
Rated 1.0 out of 5.0 by Not suitable for anything other than attic exhaust The manufacturer states that this vent can be used to vent a bathroom. The vent dosen't have a starting collar, and a regular 4 inch duct won't fit in it, making it impossible to use it for bathroom applications. October 26, 2015
