TDD Series - Vane Axial Flow Fan - Direct Driven Type

For commercial and industrial application where large volume of air is required at moderate to high pressure. Volume coefficient ranged from 0.3 to 0.6 and pressure coefficient ranged from 0.2 to 0.6. Specially designed integral straightening vanes reduce turbulence and provide high efficiency and low sound level. Both air and sound performance ratings are tested and certified by AMCA, in accordance to AMCA210 and AMCA300 Standards. 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.
