Diagonal fan for duct installation, DN 315

Product description

Features

  • For direct installation in ducts.
  • Conveying medium to large air volumes against high resistance.
  • Compact dimensions, low weight and integrated mounting plate facilitate quick installation.
  • The high efficiency reduces operating costs: Purchase price amortises after just one year, depending on operating time.
  • Suction nozzle for low-turbulence air intake.
  • Diagonal impeller with downstream stator.
  • Profiled impeller and stator blades ensure optimum air flow.
  • With diffuser to increase the static pressure.
  • Gap sealing between suction and discharge chamber reduces overflow losses.
  • Meridian flow pattern prevents turbulence.
  • IP X4 degree of protection. Exception EDR 45 to EDR 56 IP 54.
  • Temperature class F.
  • Material: Sheet steel, galvanised.

AC motor

  • Electrical connection via external terminal box.
  • Speed control possible by means of transformers.
  • Thermal overload protection as a standard feature.
  • Depending on the version, the connections of the thermal contacts must be connected to an MVE 10-1 motor protection switch or the control circuit of a contactor.
