Double facade box

Facade box exhaust is used for Jablotron Futura ventilation unit. It allows for an easy connection to EPP duct. Its construction minimizes the risk of repeated waste air intake thanks to the waste air outlet directed perpendicular to the facade while the fresh air suction is directed along the facade. Opening of the exhaust is bird-proofed with a mesh (20 mm holes). The box is equipped with a drip edge that prevents condensate from running down the wall.
