AXIAL FANS WITH DIRECT DRIVE FOR BUILDING VENTILATION AND AERATION
Based on two fans connected in series, suitable for underground car park extract air (66% redundancy in emergency mode)
- Suitable in horizontal and vertical style.
- The desired operating point is achieved with the best efficiency due to the optional number of blades (6 / 9 / 12).
- Optimised outlet guide vanes for increasing the pressure coefficients, so low-noise operation due to low circumferential speed
- Extensive adjustments to the relevant operating point and subsequent motor rating corrections can be made by steplessly adjusting the impeller blades without any need to disassemble the impeller
- The total pressure increase is double that of single fans.
- Casing available in all RAL colours
- 15 sizes
- Impeller’s nominal diameter 315 to 1,600 mm
- Volume flow rate 400,000 m3/h max.
- Total pressure increase max. 4,500 Pa
