Abstract (en)
The invention relates to a procedure and an apparatus for the cleaning of air ducts. The brushing device of the invention, supported by supporting and friction brushes (2), is moved in an air duct in the transverse direction of the duct. The direction of rotation of the drive motor (1) of the apparatus is reversed by means of a pneumatic control system, enabling the brush to move back and forth in the duct so as to produce an efficient brushing result. <IMAGE>
