Optimized for handling bags with liquid, viscous contents and frozen food. Can also be used for the same applications as for short bellows but can cope with greater differences in levels due to the longer lifting movement. Not suitable for use with deep vacuum levels. Can be equipped with reinforcement rings of polyamide to give extra stability.
