WG-KUL

Combination with a non-return damper

Combinations of external weather louvres and non-return dampers as a protection against the direct ingress of rain as well as leaves and birds, and to prevent air from flowing against the intended airflow direction.

  • Maximum width 1600 mm, maximum height 1615 mm
  • Low differential pressure due to aerofoil blades
  • Low air-regenerated noise
  • Technical data measured in aerodynamic and acoustic laboratories
  • Maximum permissible differential pressure in closing direction: 100 Pa
  • In addition to the standard range of dimensions, intermediate dimensions in millimetre increments possible
  • Pre-assembled combination, therefore fast and easy to install

Optional equipment and accessories

  • Installation subframe
  • Insect screen
  • External weather louvre, powder-coated or anodised surface

General information

Application

  • Combinations of Type WG external weather louvres and Type KUL non-return dampers for pecting fresh air and exhaust air openings in air conditioning systems
  • Pection against the direct ingress of rain as well as against leaves and birds
  • Recommended face velocity for fresh air openings: 2 – 2.5 m/s max.
  • Prevention of unwanted airflows against the intended airflow direction when the system is not in operation
  • Blades close automatically when the system is shut down


Special characteristics

  • Any intermediate sizes within the standard size range are available
  • Low installation effort on site since external weather louvre and non-return damper are factory combined and assembled
  • Operating temperature 20 – 80 °C
  • For very large sizes, several combinations can be arranged side by side or on top of each other
  • Maximum pressure of 100 Pa
  • Low differential pressure due to aerofoil blades
  • Non-return dampers are opened and closed by the airflow; no actuator is required


Nominal sizes

  • B: 200 – 1600 mm, in increments of 1 mm

External weather louvres are air diffusers for the outdoor air and exhaust air of ventilation and air conditioning systems. They are installed in external walls and façades. Their narrowly arranged blades protect against the direct ingress of rain as well as against leaves and birds.

Depending on type and intensity of the rain and the flow velocity, small amounts of water may occasionally enter together with the airflow.

Therefore, the airflow velocity in outdoor air openings should not exceed 2 – 2.5 m/s.

Non-return dampers open and close automatically.

When the system is in operation, the blades open when air flows.

When the system is shut down, the blades close due to their weight. They safely prevent air from flowing against the intended airflow direction.

Nominal sizes200 × 215 to 1600 × 1615 mm
Operating temperature-20 to 80 °C
Maximum permissible differential pressure in closing direction100 Pa

For the WG-KUL combination, the acoustic data of the external weather louvre can be used as an approximation, valid for the fully open non-return damper.
