A brochure explaining a cost-effective way to mechanically circulate fresh outdoor air within the crawl space to eliminate excess moisture is available to builders, remodelers, and homeowners. The brochure includes installation, number-of-ventilators-required calculator, performance, and dimensions. The company offers a family of crawl space ventilation fans, called Under-Aire™. All three 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 include dehumidistats that allow homeowners to select the humidity level that activates the ventilator. According to the company, UnderAire fans can be installed in minutes, require no maintenance, and are whisper quiet.
