Banish Damp Crawl Spaces

Banish Damp Crawl Spaces

Ventilation is the Answer

The Tjernlund UnderAire™ fan-powered ventilator protects your home and family by quickly reducing moisture in crawl spaces. This increased air circulation prevents mold, mildew, condensation and wood rot. It also helps vent radon gas, treated wood gases and odors, preventing them from entering your living spaces and threatening your family’s health.

Built Tough

This Tjernland deluxe two-fan crawl space ventilator is sturdily built from heavy-gauge galvanized steel and is equipped with sealed bearing fan motors rated for continuous duty. This is the only crawl space ventilator with a special ETL Safety listing “suitable for damp locations.”

Simple to Install and Use

The two-fan ventilator features a trimmable galvanized steel faceplate, so it’s easy to fit into any space. It typically mounts into ventilation openings in block foundations. Ventilator can be installed in minutes with the pre-installed power cord and included hardware packet. Fan is equipped with built-in automatic humidity control and freeze control thermostat. The controls are easy to use and understand. The UnderAire ventilator will instantly go to work, drawing out moisture from your crawl space.

How Many Ventilators Will I Need?

Calculate the cubic area of the crawl space by multiplying the length x width x height (in feet). Divide this number by 15 to determine the minimum CFM required to fully ventilate the space in 15 minutes. For example, this two-fan crawl space ventilator delivers 220 CFM and will ventilate a 3,600 cubic foot area in 15 minutes.
