Filter device for air or gas purification |
| abstract |
A filter device for purifying air or gas comprises at least one filter layer (2) which is hit and permeated by a gas flow passing through the filter device, so as to separate contaminated constituents from said gas flow. In the immediate vicinity of the front surface of the filter layer (2) that is initially hit by the advancing gas, there are mounted a plurality of flexible strips (8) of a fibrous or non-woven material which are movable with respect to said surface and adapted automatically to be set in motion by the advancing gas in order to whip or otherwise mechanically work said filter layer (2) to counteract premature clogging thereof, and adapted themselves to intercept and separate contaminated constituents from the gas flow so as to prefilter the gas flow before it reaches the filter layer (2). |
