Ventilation duct

Observance of air flows in the ventilation duct is of utmost importance for the function of the ventilation and air conditioning system. If the air flows are smaller than intended, the removal of room loads (heating, cooling and substance loads) may not be ensured in certain circumstances. Therefore, the most accurate recording of air flows as possible is particularly important.
