Axial fans VAH

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
