Fan
The fan size is dependent on the required filter performance, having regard to the maximum and minimum permissible
volumetric air flow through the filter. Refer to the table below.

The fans listed below or fans identical to them can be selected for the MDB filters and should be attached to the filter outlet by
means of ducting in accordance with the typical drawing of the system shown alongside. The fan selection should take into
account the maximum permissible volumetric air flow through the filter.

- Extraction head(s) should be connected to the filter inlet by means of duct work
- The minimum volumetric airflow of the filter is determined by the characteristics of the
extraction heads; refer to the manufacturer's data or obtain the manufacturer's approval
