  • Inertial filter
    Patent number: 9616369
    Abstract: An inertial filter to be disposed in the air flow path of a stream of air containing nanoparticles includes plural particle classifying sheets having plural mesh-like holes are disposed in the air flow path. The plural particle classifying sheets are stacked on each other in a manner that a part of at least one of the particle classifying sheets overlaps with the other particle classifying sheet. The inertial filter can adjust a classification diameter by adjusting a shadow area ratio on a projection view obtained by virtually projecting the plural particle classifying sheets from a downstream side to an upstream side of the air flow path.
    Type: Grant
    Filed: August 8, 2011
    Date of Patent: April 11, 2017
    Assignee: NITTA CORPORATION

  • Inertial filter and particle classification apparatus
    Patent number: 8978490
    Abstract: An inertial filter is placed in a fluid flow path and equipped with a particle classifying sheet having a plurality of particle classifying holes uniformly arranged. The particle classifying sheet has a sheet area larger than a fluid passage area at a site where the sheet is placed. A part of the sheet is provided in the form of a partition wall dividing the fluid flow path in two sections in a fluid passage direction to allow for classification of particles.
