The figure 16 describes how the purge sector change the direction of the outdoor air to exhaust air and by that rinses
the exchanger from remaining of extract air in the rotor material. The air handling units are delivered with the purge

Two purge sectors are built in the rotary wheel housing one on each side of the rotor as a preparation for both left and
right units. If the angle needs to be changed it is the purge sector on the supply air side.
