Properties
Sickle formed profiled impellers made of cast aluminium result in a very low noise spectrum. The main concern was to keep noise emission low in the main range of application of the fan, while having an optimal performance curve with the long and short inlet cones.
Caja de contacto
Sirve como protección contra contacto y para montar el ventilador en el cono de entrada..
Inlet cones
External dimensions according to customer requirements. If necessary, please submit a drawing.

The casings of the high-performance axial fans are manufactured from galvanised sheet steel and get an electrostatically applied powder plastic coating.
- model EQ/DQ:
- with square wall plate
- model ER/DR:
- pipe sleeve with double-sided standard flange for pipe installation
Aspas
The high-performance axial fans have aerodynamically shaped blades:
- size from 200 to 300
- made of painted and galvanised steel sheet
- size from 315 to 630-6
- made of plastic
- size from 630-4 to 1000
- made of die-cast aluminium
The impellers or blades are mounted directly on the rotor of the external rotor motors and are balanced dynamically together with the rotor according to quality level G 2.5 as per DIN1940.
Motores
- size from 200 to 300
- motor protection class IP44
- size from 315 to 1000
- motor protection class IP54
External rotor motors are used with moisture protection, with built-in ball bearings, and are designed with thermal overload protection. The drive by the external rotor motor provides a space-saving, compact and attractive design. The motor sits inside the impeller and is thus optimally cooled. For this reason, a 100% variable speed control can be guaranteed. Only well-dimensioned ball-bearings, fitted on both sides and with a long-life lubricant, are used. Both ball-bearing seats are ground to high precision in one work step to eliminate any vibration. External rotor motors are also characterised by an extremely low starting current. The windings comply with thermal class F. In addition, the windings have standard moisture impregnation.
Electrical connection
Los motores están equipados con un cable de salida. La conexión eléctrica se realiza a través de una caja de conexiones IP44 que se suministra suelta.

The casings are available as galvanised sheet steel as a standard feature. If desired, the casing can also be provided as plastic coated. The casing can be equipped with an inspection door. In the long version L, the motor and the impeller are covered by the casing length; in the shorter version K, however, the motor extends beyond the casing. The casing with defined flange hole pattern (slots for different bolt circle diameters) ensures an easy connection to the pipe system.
Motores
Drive motors three phase IEC motors model B3 protection class IP55 type with class F 2, 4, 6 or 8-pole. On request, multi-speed motors can be supplied with 2 or 3 speeds.
Aspas
Impellers, wings and hubs made of die-cast aluminium, with aerodynamically optimised profiles to achieve high efficiency and low noise. The profile angles can be adjusted at rest to obtain the required operating point.
