Louvres

Systemair array of weather-proof, high-performance louvres is made of quality materials to suit the requirements of different building types. They fit most external walling and screening applications. Available models designed as first-stage separation of airborne water, sand and dust, reducing the dust loading on ventilation filtration equipment. Selections with attractive compact yet simple design use ‘initial separation’ techniques in two stages to separate particles and return them to the face via a lower blade chute.









































A louvre is typically installed at the end of a ventilation duct as a safeguard against ingress of water, dust, sand, etc. This reduces the load on the filtration of the ventilation system. Systemair offers both louvres with or without wire mesh to prevent insects and other small animals from entering the ventilation system and thus the building. Together with other air distribution products, louvres are an important element in a ventilation system.

If you are looking for ventilation grilles for indoor installation, Systemair also has a wide selection of these.
