| 摘要 |
The invention relates 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). Said filter material (10) is connected to the housing frame (14) by means 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. |
