flow control hs11a fan

HS fans deliver improved airflow and efficiency to meet the cooling needs of new emissionized engines. Available in 610-864 mm [24-34 in.] diameters, the 11- or nine-blade fans feature a computer-optimized design. This unique construction minimizes deflection and reduces fan stress, providing more stable flow control and higher efficiency. The result is maximum cooling performance and cost efficiency with quieter operation.
