QVC 3 Vacuum Feeder

When compressed air is supplied to the vacuum generator, it creates negative pressure to form a vacuum airflow. The material is drawn into the suction nozzle, forming a material-air mixture that travels through the suction hose connector to the hopper of the feeding machine. The filter completely separates the material from air. When the hopper is full, the controller automatically cuts off the air supply, stopping the vacuum generator while the discharge Gate opens automatically, allowing the material to fall into the equipment’s hopper. Simultaneously, compressed air passes through the pulse-jet back-blow valve to automatically clean the filter. When the time limit is reached or a material level sensor signals loading, the feeding machine automatically activates.
