Low-noise fan VAH series

high-flowaxialexplosion-proof

The high-pressure axial fan type VAH is a high-performance fan with optimum aerodynamic properties. It is advantageous for high volume flows and pressures up to 3 300 Pa and is available with belt or direct drive. The impellers have 12 twisted blades with NACA 16 series laminar profiles and are made of high-alloy cast aluminum for maximum peripheral speeds and optimum efficiency. Advantages: • High volume flow • Optimum aerodynamic properties • High efficiency • Energy-efficient drives • Characteristic curve with limit power characteristic (no motor overload in operating conditions that deviate from the optimum design range) • Low-noise due to streamlined impeller and housing contour • Long service life thanks to robust design • Versions for extreme operating conditions (e.g. high temperatures, aggressive fluids) • Explosion-proof versions according to ATEX • Customized solutions
