AlorAir Crawl Space Ventilation Fan

AlorAir Crawl Space Ventilation Fans are designed to keep the air in your Crawl Space fresh, reducing humidity and improving indoor air quality. They are a great way to reduce mold growth, rot, and other problems associated with high humidity levels. Basement ventilation fans come in many different shapes and sizes, making them suitable for most any type of crawl space or basement.
Most ventilation fans are designed to be installed on the ceiling or floor of the crawl space, but some models can be mounted in a wall cavity. Our attic ventilation fans have adjustable speeds and use a thermostat to regulate when they turn on and off. This helps maintain an optimal temperature in your crawl space while reducing electricity costs. Additionally, some crawl space ventilation fans also come with air filters to help reduce dust, pollen, and other airborne allergens.
