● heating/cooling losses Condensation Condensation in the ducts may occur when the exhaust/outdoor air has high hu- midity. EXHAUSTO recommends a condensation outlet is also fitted at the lowest point in the ducts. Outdoor air intake The outdoor air intake must be dimensioned with sufficiently low airflow to prevent rain and snow being drawn into the duct system.
