The vacuum group creates a high de-pressure inside the bottle thus allowing a fast filling even for very thick products. The amount of vacuum can be adjusted according to the viscosity of the product to be filled. This filling system is widely used for both hot and cold filling of particularly thick products such as oil, some liqueurs, tomato, concentrate, thick fruit juices etc. into glass bottles or in bottles of material that can withstand vacuum.

Once the pre-set level is achieved, the product in excess is collected in a recovery tank and afterwards it can be sent again to the process system, before filling.
The filling tank is completely manufactured in AISI316, as well as all the parts in contact with the product
