Linear Grilles are used in supply and extraction lines. As they are fixed blades they can be manufactured to any desired length. The curved blade construction enables the deflection of the air. They are frequently preferred for use in air conditioning devices like fan-coil and convector type devices as they have a decorative appearance. An optional damper can be attached for regulation. The frame and blades of the linear grilles are made from aluminium and only 1st class aluminium profiles are used.
