3004509-2019-08-29 1.2 Application Comfort ventilation EXHAUSTO VEX is used for comfort ventilation tasks. Operating temperature range for the unit – see section "Technical data". Prohibited uses The VEX unit is not to be used to transport solid particles or in areas where there is a risk of explosive gases. -
Page 8: Requirements For Duct System
● 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. -
