Abstract

The invention relates to a suction device (102) comprising: - at least two casing portions (104, 116) separated by at least one seal (106), said casing portions (104, 116) forming, jointly therebetween and/or jointly with the or each seal (106), air conduits (134, 136) entering and exiting the device; - and casing portion (104, 116) attachments (130) that can be removed manually without using any tools, which secure the casing portions (104, 116) around each one of said seals (106). In certain embodiments, the casing portions (104, 116) jointly form a bracket for an air-suction motor (108), intake (134, 136) and outlet conduits for air cooling the motor (108) and/or a bracket for a collector (112, 114/182) of dust carried by the suctioned air.
