Axial fans

• Operation on a frequency inverter also permissible in the event of smoke extraction, so ideal for
• multiple-area systems (as of an NG 630 fan and a 132 motor size)
• Large volume flow rates can be realised with small nominal diameters due to high permissible circumferential speeds
• Powder coating possible in all RAL colours
• Can be installed in the fire zone if the cooling system is provided by the customer.
• Optimised outlet guide vanes to increase the pressure coefficients
• Low-noise operation due to low circumferential speeds and thus high pressure coefficients.
• 12 sizes
• Impeller’s nominal Ø 500 to 1,800 mm
• Volume flow rate V max. 320,000 m³/h
• Total pressure increase pt max 4,000

• Impellers with different blade pitch angles are used depending on the size and the desired output; please specify when ordering.
• Compact size enables installation even when space is tight.
• Motors can come with thermal contacts or a PTC thermistor
• Casing available in all RAL colours
• Also available with acoustic insulation.
• Efficiency up to 63%
• 15 sizes
• Impeller’s nominal Ø 315 to 1,250 mm
• Volume flow rate V. max. 140,000 m3/h
• Total pressure increase pt max. 1,500 Pa
• M style – with direct drive. Impeller assembled directly on the motor shaft.

• For installation in the fire zone without additional cooling.
• Low-noise operation due to low circumferential speeds and high pressure coefficients.
• Optimised outlet guide vanes to increase the pressure coefficients.
• 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 impeller blades cannot be adjusted in the case of the F400 temperature class).
• The desired operating point is optimised to achieve the best possible efficiency using a variable number of blades (6 / 9 / 12).
• 15 sizes
• Impeller’s nominal diameter 315 to 1,600 mm
• Volume flow rate max. 230,000 m³/h
• Total pressure max. 3,150 Pa
• Casing available in all RAL colours
