Product description

Features

  • The series was developed especially for the tough operating conditions of a kitchen exhaust air fan.
  • Double-walled housing made of galvanised sheet steel, for high demands and especially low noise levels.
  • Supply of medium to large air volumes at high resistances.
  • Not sensitive to hot airstreams of up to 120° C.
  • Inlet and outlet side connection sockets for direct installation in ventilation ducts, with double sealed lips.
  • With mounting track and 4 vibration dampers.
  • Fan unit can be swivelled out for cleaning and maintenance.
  • Motor located outside of the air flow.
  • With condensation drain if the exhaust socket points upwards.
  • Strong centrifugal impellers with backward curved blades.

Motor

  • Motor can be regulated by transformers using voltage reduction.
  • Terminal connections for thermal contacts.
  • Motor protection through an external MAICO MVE 10 triggering device.
  • IP X4 degree of protection for closed housing covers as well as duct connections fitted on the inlet and outlet sides.

Mounting instructions

  • Installation with upward, right-hand or left-hand exhaust sockets.
  • If the unit is mounted with the exhaust socket pointing to the left or the right, the service door must be altered by the customer.

Electrical connection

  • Externally fitted terminal box with cable screw-connection.

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.
