The DHEB and THEB models can simultaneously vent from multiple sources, offer duct size options in 4”, 6” and 8”, and are available in various configurations. Separator fins keep exhaust venting from interacting with each other within the cavity box.
X Vent Box incorporates a removable front louver and an integrated back draft damper
for easy inspection and maintenance without damaging any weather-tight seals
The molding process creates a monolithic box cavity that combined with an integrated balanced gravity dampers X Vent Box provides a superior barrier against wind driven rain. Our products successfully prevents water from breaching the exterior building envelope, even in extreme conditions like hurricanes or high wind event.
Differences in air moisture content and/or temperatures between interior and exterior can create conditions in which mold thrives and the deterioration of construction materials accelerates.
When wind encounters the basic vent cap it rattles the damper (if there is any), or even rips it off. People in beach/lakefront residences often find themselves kept up at night by wind. Our unique design makes use of windy conditions to make the damper close more securely, eliminating wind generated noises.
The front louver allows for proper air flow but prevents birds or other creatures from taking residence. Dealing with animal feces, and noise associated with nest-building, are not pleasant either. Our design makes it “Critter Proof” preventing birds or squirrels to access the duct, and insect access unlikely.
