short description

Sound-insulated ventilation box, DN 125, single-phase AC

Product description

Features

  • With 50 mm sound absorbing mineral fibre plates to meet the increased requirements for especially low noise levels.
  • Inlet and outlet side connection couplings for direct installation in ventilation ducts.
  • Removable housing cover fitted with clip-locks - enables easy and quick cleaning of the ventilation box.
  • Centrifugal impeller made of galvanised steel, with forward curved blades.
  • Statically and dynamically balanced in accordance with DIN ISO 1940, balance quality 6.3.

Air flow direction

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

Motor

  • External rotor - capacitor motor.
  • Thermal overload protection as standard feature.
  • Robust motor with ball bearings, maintenance-free.
  • Temperature classes B or F.
  • IP 44 degree of protection for closed housing covers as well as duct connections fitted on the inlet and outlet sides.
  • There can be a physically induced humming noise, through the use of phase angle technology. 5-step transformers are therefore used for speed control in rooms requiring quiet fan operations.

Mounting instructions

  • Can be fitted in any position.

Electrical connection

  • Flexible connecting cable, 2.5 m long.

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.
