<p>The present invention refers to a precipitator having a through-flowing passage for the air to be purified, said precipitator being intended to be included in an air purification device, especially for purifying air from electrically charged particles, said precipitator being electrically connected to a high voltage source and comprising at least two electrode elements (01, 02) or groups of such elements (011, 022) arranged at different potential relative to each other, said electrode elements (01, 02) and (011, 022) respectively being designed as band-like strips that are arranged to circle at least once, and preferably several times, around an imaginary axis at a gap distance (d), seen in radial direction relative to the imaginary axis, from adjacent electrode elements (01 and 02 resp.) or (011 and 022 resp.), that the extension of the electrode elements in the air flow direction is essentially less than their circled length around the imaginary axis. The invention also refers to a method for manufacturing a precipitator according to the present invention. The invention is characterised in that the edge sections of the electrode elements (01 and 02 resp.) or (011 and 022 resp.), preferably at one side only of the body (00) of the precipitator, are fixed relative to each other by the aid of fixing material (05).</p> |
