A positive displacement blower moves gas or air from the upper inlet port into the stage using two parallel rotary pistons mounted within the conveying chamber, or blower housing. The pistons rotate in opposite directions to facilitate the conveyance of gas or air from the top to the bottom. Positive displacement blowers are commonly called PD Blowers or Rotary Blowers and are typically categorized as a lobe type or a screw type.
