Crawl Space Ventilation Fans Protect Home Structure and Promote Health of Occupants
White Bear Lake, Minn. —A family of new crawl space ventilation fans, called “UnderAireTM”, developed by Minnesota based-Tjernlund Products, offer homeowners a simple, easy and cost-effective way to mechanically circulate fresh outdoor air underneath homes and porches. Left untreated, high humidity in these enclosed areas can foster a myriad of structural problems including premature rotting of structural support columns, joists, floors and beam supports (increasing the potential for termite infestation) as well as plumbing failures due to rusting and corrosion. On the other hand, proper ventilation helps vent radon, suppresses mold, off-gassing from treated lumber and odors that might otherwise migrate into living areas.
Tjernlund’s UnderAire fans are the only crawl space ventilators currently listed by ETL as “suitable for damp conditions.”
All three UnderAire models have factory-installed freeze protection thermostats that prevent the units from operating if temperatures are below 40° F. The two deluxe models come ready to plug into an electrical outlet and also include a dehumidistat that allows the homeowner to select the humidity level that activates the ventilator.
Tjernlund UnderAire fans can be installed in minutes, require no maintenance and are whisper quiet.
Complete UnderAire information, including installation, number-of-ventilators-required calculator, performance and dimensions is available at www.tjernlund.com/retail or by calling 800-255-4208.
