Axial fans

EC Axial fans (Type: AKFG)

Properties

  • flow rates up to 32,000 m³/h
  • size: 500 - 1000 mm (impeller diameter)
  • highly efficient EC technology
  • sickle formed profiled impellers made of cast aluminium
  • integrated control system (EC controller)
  • speed is 100% infinitely variable

» Design and Downloads

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.

Guard

Serves as contact protection and for mounting the fan onto the inlet cone.

Inlet cones

External dimensions according to customer requirements. If necessary, please submit a drawing.

Properties

Sickle formed axial impellers 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. The impellers are designed as follows:

size from 350 to 450
made of sheet steel
size from 450N to 630
of aluminium sheet

Guard

Serving as contact protection and for mounting the fan onto the inlet cone.

Casing

The casings of the EC axial fans are manufactured from galvanised sheet steel with white powder plastic coating and protection guard with black powder plastic coating.

Impellers

The EC axial fans have aerodynamically shaped blades:

size 200
made of plastic
size from 250 to 400
made of black painted and galvanised steel sheet
size from 450 to 1000
made of aluminium

Electrical connection

The electrical connection can be made at the motor size G9, V8, GD84 and GD112 (230V) via lead out connection cable and for the motor size GD112 (400V) and GD150 directly via cable gland at the integrated terminal box of the motor. The integrated motor protection is signaled via alarm relays at size 350 to 1000. For the size 200 to 300 a tachometer output is available. In the version „open-loop control“(standard) the speed is adjustable via 0-10V Signal or a potentiometer (optional).

Casing

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

Impellers

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 dynamically balanced on two levels with the rotor according to quality level G 2,5 / G 6,3 as per DIN ISO 21940-11.

Motors

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

The motors are fitted with an outgoing cable. The electrical connection is made via an IP44 terminal box which is supplied loose.
