4.5 Air flow guide plates
Air flow guide plates direct the air that is blown from the ventilator. Various configurations are possible
to control the air flow. The configurations presented in chapter 4.5.1 are tested by VDEG on their desired
effect. However, due to differences in installations, it is recommended to perform a single test prior to
implementation, in order to obtain the most desirable effect.
4.5.1 Configuration of the air flow guide plates
The number of guide plates attached to the Enfan and their orientation are vital for determining the air
flow. The configurations with one guide plate are shown in Figure 12. The left configuration restricts
the airflow downwards whilst the right restricts the flow upwards. A downwards restriction might be
necessary if the airflow affects the crop too much. An upwards air flow restriction is imposed when the
flow affects the screen cloth too much.
Figure 12 Downward (left) and upward (right) air flow restriction
If the configurations in Figure 12 do not influence the air flow enough, one can choose to use two air
flow guide plates to restrict the flow. Figure 13 shows these configurations. The left configuration is used
to limit the downward air flow even more. Respectively, the right configuration limits the upward flow
even more than the one in Figure 16 does.
