External weather louvres are externally mounted air transfer devices for the fresh air and exhaust air of air conditioning systems. They are installed in external walls and façades. Their narrowly arranged blades give good protection against the direct ingress of rain as well as against leaves and birds. Under certain unfavourable conditions, such as heavy rain, and depending on the airflow velocity it might happen that slight quantities of water enter together with the air. This is why the airflow velocity in fresh air openings should not exceed 2 – 2.5 m/s.

Linkage

Multileaf dampers with external linkage can have parallel action blades or opposed action blades. An external linkage transfers the synchronous rotational movement from the drive arm to the individual blades. Even very large multileaf dampers can be safely opened and closed with this type of linkage. Opposed action blades close at different speeds since the linkage includes a transverse link. This facilitates the closing process and reduces the closed blade air leakage.

Nominal sizes

200 × 180 to 2000 × 1995 mm

Operating temperature

-20 °C to 100 °C

Maximum permissible differential pressure

1000 to 2500 Pa (depending on size)


For the WG-JZ combination, the technical data of the external weather louvre can be used. Thereby, a fully opened multileaf damper is assumed. This does explicitly not apply to different damper blade positions. You can find the Easy Product Finder for sizing on our website: www.trox.de/mytrox/auslegungsprogramm-easy-poduct-finder-182e16348fac3d33

Combinations of an external weather louvre and a multileaf damper. Rectangular external weather louvre as a protection of air conditioning systems against the direct ingress of rain, leaves and birds into outdoor air and exhaust air openings. Rectangular multileaf damper for volume flow and pressure control as well as for shutting off air ducts and openings in walls and ceilings. Ready-to-install component which consists of a front frame, aerofoil rain defence blades, and a crimped wire mesh grille at the rear. Shut-off damper which consists of the casing, aerofoil blades and the blade mechanism. Suitable for duct pressures up to 1000 Pa. Suitable for mounting air duct profiles. The blade position is indicated externally by a notch in the blade shaft extension. Casing air leakage according to EN 1751, class C.
