Crawlspace Ventilation Fans

The crawl space is the most common place for moisture and mold because it is dark and enclosed. Ventilator fans are a great invention to solve this problem. If you have a wide crawl space, then it can assist the dehumidifier to increase airflow and air velocity. While your crawl space is narrow, they are the right size to install on the wall to help you circulate the ventilation.

AlorAir ventilation fans are designed for maximum airflow, portability, and efficiency. Some have an IP55 rating, dust and water-resistant. The humidity range is adjustable from 5%-80% RH for any crawl space from 2400-7400 Cu. Ft.
