YL is a unique weatherproof louvre with an arrangement of parallel blades, designed to protect air handling systems against the direct entry of rain, leaves and birds into supply and exhaust air openings. We have carefully selected raw materials such as aluminum and alu-zinc to guarantee a long-lasting durability, which further combined with the specially shaped, angled profile ensure low differential pressure drops, minimum noise levels, effective drainage and an overall protection for the ventilation system.
The frame and the deflectors are made of aluminum, thus meeting the requirements of the C4 corrosion class. On request powder coating is available in accordance with RAL spectrum, or the product can be ordered with anodized aluminium profiles.
The specified size is the nominal connector size of AxB. Can be ordered in standard sizes ranging between 200x200 mm and 2050x2050 mm with 50 mm increments. In special circumstances it is possible to order sizes above 2050x2050 mm, in this case the rain-proof louvres will be manufactured from multiple pieces assembled with a narrower frame where the pieces join, similarly with 50 mm increments.
The maximum length of a profile (air deflector) is 700 mm. In case of larger sizes the profiles are made up of more pieces.
Weight is 15 kg/m².
Please see the attached technical datasheet.
Mounting frame: FR.
