What must be considered in the exhaust air planning?

The Basic and Classic product series can be operated with a duct length of maximum 6 metres and with six 90 degree bends. Depending on this, the airflow rate decreases and efficient extraction is no longer guaranteed. If it is necessary to overcome a distance of more than 6 metres, the series Professional series will be more suitable, since different fans can be fitted in line one after another. Thanks to each new fan added, we can extend the duct length by up to six more metres. A careful and professional planning is important, because it guarantees a long-term and perfect extraction operation.
