Can a container be connected dust-tight?

It is possible to unload a container dust-proof or dust-free. This may be necessary, for example, when unloading hazardous substances. A movable unloading head is raised after the container has been placed on the unloading station. Sealing material, such as foam or foam, has been applied to the discharge head. An inflatable cuff can also be used for dust-free unloading of containers.
