Abstract
An air filter includes a honeycomb rotor which carries a porous adsorbent and can be rotated in a circumferential direction, a drive means for rotating the honeycomb rotor, a first partition member provided with a first gas introduction section and a second gas exhaust section and a second partition member provided with a first gas exhaust section and a second gas introduction section, the first and second partition members being disposed on both sides of the honeycomb rotor respectively to allow two gases to flow in counter current to each other and to pass through different conduits respectively, a heater disposed at the inlet port of the first gas introduction section, a drive controller for controlling the drive means such that the honeycomb rotor can rotate intermittently by every part of a regenerative/purge-zone facing the first gas introduction section among the surface of the filter of the honeycomb rotor.
