(57) The control unit for centralized vacuum cleaner systems, of the type comprising a
central body or stage (4), which is provided with an input duct (500) of the suctioned
air, and is closed on the top by a head stage (9), bearing an output duct (901) of
the filtered air, and is equipped on the bottom with a container (1) for collecting
the dust, is characterized in that it comprises rapid hooking and releasing means
(3, 102) of the said container (1) to the central stage (4), allowing the container
(1) to be easily removed and inserted through simple frontal movement by a single
operator, manually and without making use of tools; means (700, 701, 8) for reducing
the noise level of the control unit; means (5, 900, 902) which allow to choose directly
on the way on which side to arrange the input of the suctioned air and the output
of the filtered air, independently one from each other, thus making the control unit
fitted to the conditions of any system to serve; means (5, 6) for fixing the control
unit to the wall by simple frontal push, which allow the control unit to be positioned
in small places or even in a built-in box, since it does not require any lateral and
vertical movements; means (404) for protecting the filter (200) from any possible
dangerous objects dragged with the suctioned air; means for the self-cleaning of the
filter (200).
