KTF Series - Tunnel Axial Fan

KTF Series are axial mixed flow fans designed with high strength material to serve tunnel ventilation application such as Transportation Tunnel, Underground Construction, Utility Tunnel, Wind Tunnel, etc. Fans are provided with non-stall design or anti-stall ring ensures stall-free operation and protect the ventilation fans and upstream/downstream equipment from potential damage. Truly Reversible (Reversibility of 97-100%) airflow direction is available. Air performance ratings are tested and certified by AMCA, in accordance to AMCA210 standard. High temperature (up to 400°C/2 Hours) in accordance with EN12101-3 certification by TÜV SÜD a third party globally renowned testing and certification organisation. All impellers are statically and dynamically balanced to ISO1940 and AMCA204 - G2.5 standards.
