Description of the L series axial fans (blowers).
The axial fans of the L series are designed for lower pressure with higher volume flow rates at the same time.
Range of application of the axial fans
The blowers are suitable for use on heat exchangers, in refrigeration technology, ventilation technology such as ventilation systems and for separate cooling of industrial fans.
Technical description of the blowers
The axial fans are controllable over the entire voltage range, i.e. the volume flow is continuously adjustable via the speed.
The nominal diameters of the axial fans of the L series are:
- Diameter with 250mm
- Diameter with 300mm
- Diameter with 350mm
- Diameter with 400mm.
The nominal speeds are from 1400 rpm up to 2800 rpm. This covers a range of volume flows from 0 m³/h to 5500 m³/h.
Speed controllers for axial fans
Speed controllers 400V and speed controllers 230V are available for the control.
CO2 controllers, air quality controllers and temperature controllers are available for the control of the fans. The fans can also be controlled with frequency converters in compliance with DIN-IEC/TS 60034.
Technical characteristics of the blowers
The standard protection class of the blowers is IP 44, but IP 54 and up to protection class IP 66 are also possible on request.
The permissible temperature range for storage and transport is -40°C to +60° C. This makes the axial fans suitable for use in ventilation and refrigeration applications.
The fans are designed according to continuous duty class S1.
In the range of nominal voltages, everything from 230 volts alternating current to 400 volts three-phase current is covered. Special voltages of 480Volt, 60Hz and 575Volt, 60Hz for the North American market voltage USA, voltage Canada, Mexico) are also available.
Ecodesign Directive ERP 2015
All L series fans are energy efficient in accordance with the Ecodesign Directive ERP 2015 (ErP Directive 2009/125/EC EU Regulation No. 327/2011).
Stainless steel fans V2A and V4A
The axial fans, blowers of the L series are also available as stainless steel fans in V2A (material number 1.4301 or ANSI 304 or X5CrNi189) for the food industry. Furthermore available as stainless steel fans in V4A (material number 1.4571 or ANSI 316 or X10CrNiMoTil810) for salty air (offshore).
Air directions and installation types in different shapes can be ordered when placing the order.
In addition to plastic impellers, aluminum impellers are also available for the L series axial fans.
