There are various functions this device is capable of, including testing welding sealing in flow-pack applications, as well as in the case of cellophane or food product wrappings. The products are comprised of a transparent plexiglass cylindrical container, which benefits from creating a vacuum by pouring water. The mobile transparent plexiglass lid is placed on the lower part, delivered with a perforated disc that is fixed via a pin, suitable for keeping the flow-pack wrapping submerged in water.
The multiple ejector, multistage vacuum generator and location of a check valve on the generator suction inlet, prevent air from returning to the container. A sleeve valve is provided for compressed air interception, while a pressure gauge was also included. Finally, the role of the two-way manual valve is to restore the atmospheric pressure inside the container.
