This 12-inch crawlspace ventilator fan is engineered to regulate humidity, temperature, and airflow in enclosed spaces such as crawlspaces, basements, attics, and garages. It creates strong exhaust airflow to remove stale air, moisture, and odors, helping protect your home from mold, mildew, and structural damage.
The dual 120mm DC fans use PWM technology to maximize airflow with minimal noise and power consumption. Built from heavy-duty anodized aluminum with IP55-rated fans, the system provides long-lasting resistance to dust and moisture. The included 10-speed controller makes it easy to fine-tune ventilation performance for different environments.
