Integrated dust extraction
Machines which would be considerably less mobile with an attached vacuum hose usually come with built-in (integrated) dust extraction. A second extractor fan wheel attached to the motor drive shaft ensures internal dust extraction. This is quite common with belt and orbital sanders, universal routers and finishing sanders.
With light rotary hammers dust and debris is removed with the help of an extractor attachment and the integrated dust extraction. The suction capacity of this hammer is approximately 500 l/min.
