Quiet & Efficient, Inline
Mixed Flow Fans
Mixed flow inline fans can be used for supply, exhaust, or return air installations. Our patented design excels in commercial applications where low sound is critical. In addition, Greenheck’s mixed flow fans are more efficient than comparably sized tubular centrifugal and vane axial fans, thus reducing the required motor horsepower and lowering operating costs.
Greenheck’s mixed flow fans are the quietest tubular inline fans in the industry!
