The pneumatic cylinder design is slow and cumbersome. Operation in dusty environments can cause premature seal wear; this results in erratic, unreliable arm movement.


Updated Design
The motor drive assembly with VFD controller provides smooth, consistent operation at rates up to 12 bags per minute.
