Document Type and Number:
WIPO Patent Application WO/2023/166591
Kind Code:
A1
Abstract:
Provided is a filter unit having a low pressure loss. A filter unit (2) comprises: an electrode group (7) in which ground electrodes (4) and high-voltage electrodes (5) are alternately arranged apart from each other; and an insulation fiber filter (6) in which the respective longitudinal directions of insulation fibers are oriented in a single direction. The electrode group is provided with a flow passage through which air flows in one direction along the ground electrodes and the high-voltage electrodes. The insulation fiber filter is disposed within the flow passage such that the orientation directions of the respective insulation fibers are identical to the direction of the flow passage.
