We had the dual head fillers. The lifts worked great. When you use the lifts you fill from the bottom up it keeps dust from getting on the threads of the container or the neck of container. Everything running really smooth and clean. I never saw the worm gear feeding the containers like that which we didn’t have for our fillers. We used the vibration intermittent or full. I liked the intermittent, fill in station. If we needed a twin shot fill to make wt it was good so excess dust wouldn’t stay on jars. Sometime a vacuum recovery to take the dust away. These fillers are great they can put 10lb of prouduct in a 5lb jar
