Functional description
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.
Nominal sizes | 200 × 165 – 2400 × 1650 / 1600 × 2310 mm |
Width subdivided | Up to 4900 mm |
Height subdivided | Up to 4720 mm |
Horizontal runs (WG-B-AL) | H: 165 – 1980 mm |
Volume flow rate range (undivided construction) | 40 – 9390 l/s or 144 – 33804 m³/h at 2.5 m/s |
Free area | Approx. 60 %, with insect screen approx. 45 % |
Total differential pressure – exhaust air | 30 Pa at 2.5 m/s |
Total differential pressure – fresh air | 35 Pa at 2.5 m/s |
Quick sizing tables provide a good overview of the volume flow rates with an airflow velocity of 2.5 m/s. Values for intermediate widths can be interpolated. Precise intermediate values and volume flow rates for other airflow velocities can be calculated with our Easy Product Finder design programme.
The sound power levels LWA apply to external weather louvres with a flow cross section of 1 m².
Sizing example
Given data
V =1400 l/s (5040 m³/h)
v = 2.5 m/s
Fresh air, installation type B
Maximum width: 800 mm
Quick sizing
WG/800 × 825 mm
Calculation procedure
A = 0.800 × (0.825 –0.085) = 0.592 m²
v = V ∕ A = 1400 ∕ 0.592 ( ∕ 1000) = 2.4 m/s
Δpst = 35 Pa
LWA = 50 dB(A)
