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.

The casing design and construction are well suited for indoor or outdoor applications and can be easily installed in ducted or non-ducted systems. The RA fan is designed to significantly reduce operating costs with peak total efficiency ranging from 70-86%.
