Axial fan VAN series

Product overview
The low-pressure axial fan type VAN is a high-performance axial fan designed for high volumetric flow in compact central systems. It features a welded steel housing and impellers with 10 twisted blades using NACA 16 series laminar profiles, manufactured in high-alloy cast aluminium to allow high peripheral speeds and optimum efficiency.

Advantages

• High volumetric flow even in small sizes
• Optimal aerodynamic performance
• High efficiency (up to 89.5%)
• Energy-efficient drive options
• Characteristic curve with limit-power behaviour (no motor overload in off-design operating conditions)
• Low noise due to streamlined impeller and housing contours
• Long service life from robust construction
• Versions for extreme conditions (high temperatures, aggressive media)
• Explosion-proof variants according to ATEX
• Customized solutions available
