Tube Axial Direct Drive
The direct drive version of the tube axial inline fan may be the chosen if looking for a duct fan for a tighter space, lower maintenance than a belt drive unit, or a lesser cost for moving air in or out of a space. These inline fans are for dry environments only, such as welding shops. If moisture is present, a wet environment fan may be necessary. If space is even more limited, a square inline duct fan may be considered.
