External air inlet canopies protect the elements of the frame (windows, casings) hosting the air passage holes against bad weather and water infiltration. Their role is also aesthetic: they blend in perfectly with the frontage and windows.
By ensuring the continuity of the airflow from the outside canopy to the air inlet, the E-TFR protects the interior of the window and avoids cooling to prevent internal condensation.
Not only does the AC external canopy protect the interior of the window from water infiltration and volatile insects, it also controls the airflow to avoid over-ventilation in case of excess of pressure through a patented device. This ability makes the AC canopy particularly suitable for tall buildings or windy locations. The AC external canopy can be installed with either fixed or humidity sensitive air inlets.
