Abstract (en)
[origin: EP0046137A1] 1. Cleansing hood for gaseous fluids, comprising an exterior housing (1), a motor (5) driving a rotor (13) adapted to generate simultaneously a ventilation function and a purifying function of polluting solid and liquid particles suspended in the fluid to be purified, characterized by the fact that the polluting particles are removed by adsorption on corrugated surfaces which make up said rotor, such as to produce a turbulent flow around these surfaces and to constrain said flow to sweep over the said surfaces without passing through them, the rotor being followed by a filter (21) designed to neutralize or transform the undesirable gaseous components contained in said fluid flow following the purification effected by the rotor.
