Abstract (en)

[origin: EP2481522A2] The method involves generating a large volume of air flow by a fan (11) of a grinding tool (10). The erosion particles are raised from the surface and conveyed through the grinding tool. The air flow is blown from an outlet opening (12) into a pipe (14) and through the pipe to a filter device (18) attached to the pipe. The filter device is pressurized for filtering the erosion particles. An independent claim is also included for a device for removing erosion particles, such as dust and solid particles generated during floor or wall surface treatment by a motorized grinding tool.
