Belt- and direct-drive adjustable, pitched-vane axial fans are designed to efficiently move high volumes of air using a minimal amount of space, says the manufacturer. The compact vane axial fans include airfoil-shaped case aluminum blades and integral straightening vanes that work together to provide mechanical efficiencies of up to 75%, says the company. The fans are designed for use where space is limited, such as in new construction or retrofit situations.
