摘要 |
This publication discloses an electrostatic filter construction (2), which includes electrodes (14) connected to a first electrical potential, second electrodes (15), which are electrically insulated from the first electrodes (14), and an insulating material (12) acting as a particle filter, which is located between the first (14) and the second electrodes (15). According to the invention, in both of the electrodes (14, 15) the electrode material used is a material, such as activated carbon, which is permeable to a gas and which filters the gas, and which has a low electrical conductivity, and both electrodes (14, 15) are located essentially parallel to the direction of the airflow. |
