Vane Axial Fans

Vane Axial Fans

Vane axial inline fans are the most efficient axial design. Precision machining creates a tight tip clearance between blade tips and the fan housing. Integral straightening vanes redirect swirling airflow after the impeller into a linear flow at the discharge, further adding increased efficiency. Best suited for applications where there are high volumes of air at medium to high pressures, applications include mining, tunnel ventilation and large space ventilation such as atriums, halls, and stadiums.
