Delanair Mk III blower fan photos
Removed the fan to secure the duct assembly to it. Fresh air inlet is on the right, recirculation inlet is on the left. They are linked, when one is open the other is closed.
Top view, this is the flap that would bring fresh air into the car.
Bottom view. This is the recirculation vent. If it's open, in cabin air goes into the fan and them back through the duct system. If it's closed, then the top vent is open, and fresh air is allowed in.
Side view showing the vacuum actuator. It completely opens with a vacuum of about 12" Hg.
