Product Description
Direct-drive fans help to ventilate a fume hood. They feature a propeller that's directly mounted on the motor shaft. This reduces friction and improves efficiency when compared to a belt-drive fan. Direct-drive fans also have fewer moving parts and typically require less maintenance than belt-drive fans.
