Diagonal fan for duct installation, DN 250

Product description

Features

  • For direct installation in ducts.
  • Displacement of medium to large air volumes against high levels of resistance.
  • Compact dimensions, low weight and integrated installation plate simplify fast installation.
  • High efficiency reduces operating costs: Depending on level of use, purchase price is amortised after just one year.
  • Suction nozzle for turbulence-reduced air intake.
  • Diagonal impeller with downstream stator.
  • Profiled impeller and stator blades ensure optimum flow.
  • With diffuser to increase static pressure.
  • Gap sealing between intake and pressure chamber reduces overflow losses.
  • Meridian flow course prevents turbulence.
  • IP X4 degree of protection. Exception EDR 45 to EDR 56 IP 54.
  • Insulation class F.

AC motor

  • Electrical connection via external terminal box.
  • Speed can be controlled using transformers.
  • Thermal overload protection as a standard feature.
  • Depending on versions, thermal contacts must be connected to an MVE 10 full motor protection switch or the control circuit of a contactor.

Electrical connection

  • 50 Hz power frequency.
