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
