The airlock acts as a seal between the vacuum and atmosphere sides of the machine and is located at the bottom of the collector cyclone tank.
As the airlock rotor turns, a pocket is filled with material when it points upward. As the pocket rotates, it is moved to the bottom where the material drops out of the pocket into the discharge pipe.
