Hose for vacuum on:
Vacuum is made on the back
of the bag, and the bag is
kept open for collection
directly into the bag.

Now the machine is equipped with hose for vacuum.
This device will make sure that a vacuum is formed on the outside
of the Longopac bag, which is in this way kept open.
Furthermore the hose for vacuum can be deaerated to
atmospheric pressure, so that it will be possible to remove the
container.
If a flap valve is installed, the machine can be emptied during
operation.
If no hose for vacuum is installed, the air caught between the bag
and the container wall will expand, when vacuum is made in the
machine, and will consequently push the bag up into the machine.
NOTE: Do not open the air escape valve during operation, if no
flap valve is installed. There is a risk that the material collected will
be pushed up into the machine.
Hose for vacuum off:
Suction and atmospheric
pressure are closed.
