The Sine design favors the entry of air, disables the view to the interior of the machine rooms and blocks the entrance of rain unlike other proposals that offer high percentages of aeration but with a minimal visual coverage. Storm pressure drop values do not make this product recommendable for areas of high demand air conditioners because its design does not facilitate the flow of air (inlet / outlet) making it difficult to vent the equipment.
The Sine model incorporates details in its design that guarantee minimum levels of rainwater entry even in extreme wind pressure conditions. In addition, based on the result of the resistance test that determines a class 5 value for this louver (> 249 km / hour), its specification in hurricane areas is recommended.
