Abstract
In an extraction device comprising a suction apparatus (16) with an electric motor (32) and an centrifugal separator (14) exhibiting an inlet cylinder (22), a vertically arranged dip pipe (30) and a lateral suction nozzle (24) through which a laden gas stream enters the inlet cylinder (22), it is provided with a view to creating a low-cost and easy-to-handle extraction device of a compact design, having a centrifugal separator, that the electric motor (32) is arranged inside the dip pipe (30).
Claims15
An extraction device comprising:
- a) a suction apparatus (16) with
- b) an electric motor (32) and
- c) a centrifugal separator (14) having an outflow exhibiting
- d) an inlet cylinder (22),
