<p>The invention related to dust filters ( 1 ) which are especially used in operations endangered by gases and comprise filter elements ( 10 ) rendered antistatic by means of derivative constituents such as carbon fibres, salts or special steel fibres ( 26, 27 ). The filter material ( 10 ) is connected to the housing frame ( 14 ) by use of conductors ( 16 ), bypassing the seal ( 15 ), in such a way that a negative electrical charge of the inner chamber of the individual filter element ( 10 ) or the dust filter ( 1 ) is avoided.</p> |
