    About BK-3
     
    Roots blower is displacement type air compressor. Two parallel shafts have three lobes each, all the lobes keep small clearance with each other and housing inside. Every lobes rotation, a certain air will be absorbed at inlet and transferred from the housing inside surface to blower's discharge port.

     

    Two shafts are turned by the timing gears, without touching with lobes, so it can be turned at high speed without any lubrication inside.
