Systems Used for Powders or Dusty Materials
Material lines on the vacuum side of the conveying system typically lead to a self-
cleaning filter receiver, where material is separated from the airflow and passes through
a rotary airlock for transfer to the pressure side of the system. You can order the self-
cleaning filter separately.
Systems Used to Convey Clean, Pelletized Material
Systems with solid state control units are used to convey clean, pelletized material. A
cyclone separator is furnished in the system to remove material from the vacuum side
airflow. A filter chamber is also furnished to clean the air entering the vacuum unit.
