Abstract

A multiple action filter for retaining in the interior particles which are harmful to health, cause cancer or are in any case pollutants, contained in gaseous flow. The first action is to channel the flow into a conduit suitably dimensioned to increase the velocity and at the same time enhance the adhesion of the particles to be eliminated into an adequate filter element. The second action is to slow down the flow so that it no longer has the energy to detach the particles from the filter element, and the particles therefore do not reach the filter outlet.
