Multifan Recirculation Fans: Creating a uniform climate

The Multifan 20in. Q Greenhouse Fan is designed for heavy-duty, high moisture laden ventilation and circulation in a greenhouse. This fan exhibits exceptional performance in high moisture or wet environments. Unique housing design creates tighter airflow patterns for enhanced air movement throughout the greenhouse without plant disruption.
