The dust containers are used for the local air filtration where only a small volume of dust appears (such as dedusting of welding fumes).
The usual volume of the dust container is 60 litres.
In the case the bigger dust container is needed, it would have a volume of 450 litres. Such container is easy to manipulate with the forklift.
Dust containers are an integrated part of the dust collector, which they seal under pressure. It is not permitted to operate the dust collector without the attached dust container.
