short description

Sound-insulated ventilation box with swivelling fan, DN 250, alternating current

Product description

Features

  • Optimised efficiency, low maintenance costs.
  • Removable housing cover with clip-locks.
  • Inlet and outlet side connection couplings for direct installation in ventilation ducts.
  • With sound absorbing rock wool, laminated with silk glass, to meet the increased requirements of especially low noise levels.

Air flow direction

  • The airsteam direction is indicated by an arrow marked on the housing.

Motor

  • External rotor-capacitor motor.
  • Robust motor with ball bearings, maintenance-free.
  • The motor's standard rubber mounting prevents vibrations being transferred to the housing.
  • Temperature classes B or F.
  • IP X4 degree of protection with closed housing cover.

AC motor

  • Thermal overload protection as a standard feature.

Three-phase AC motor

  • Potential-free terminal connections, which must be connected to an MV 25 protective motor switch or the control circuit of a contactor.

Mounting instructions

  • Can be fitted in any position.

Electrical connection

  • Terminal box at front.

Safety instructions

  • The fan may be operated only if the protection against accidental contact with the impeller is guaranteed to be in accordance with DIN EN ISO 13857 for fans with free inlet or outlet. To do this, fit a protective grille.
