5 + 5.a + 6) Flap Valve:
Are used if you want to continue the work during emptying (with hose for vacuum, container and Longopac).
The flap is locked, and the container can – after pressure equalization by the hose for vacuum – be pulled out
together with the Longopac bag. Then you can dispose of the bag.
The dust being collected in the meantime will remain in a buffer above the flap valve until the flap valve is
opened again.
The flap valve can be locked during transport or change of dispenser, if you want to prevent the dust from
being sprinkled from the machine.
The flap valve can be used with dispenser without grating for the collection of threads etc.
4 + 6) Hose for Vacuum and Container:
This unit is used to create a negative pressure on the outside of the bag, when a plastic container is used.
It is necessary to use a plastic container with hose for vacuum, if you want the collected material to be emptied
directly into the bag. The bag is drawn to the outside wall of the container, and the collection capacity of the
bag will be equal to that of the container, before the machine is to be stopped / emptied.
This composition is to be used, if the material to collect is frayed, as you can use the Longopac dispenser
without grating (81.89.0076).
If dust hazardous to health is to be collected, it is recommended always to use a plastic container for the
protection of Longopac so that no external influence (objects) will tear a hole in the bag.
REMEMBER – if you want to use the hose for vacuum you must also buy a 40 litres container (81.77.3982).
REMEMBER – if you want to use the hose for vaccum with flap valve you must also buy a 25 litres container
(81.77.3985).
