| Research Abstract |
During test of developed devices at living environments with rather high nano-particle concentration such as roadside, smoking area and working environments, we improved the inertial filter technology by precise control of separation size by careful selection of spacer size and pressure drop reduction by using bell-mouth inlet. In order to reduce dust load on the main inertial filter, a pre-separator consist of impactor and inertial filter stages was designed to use upstream part of the main inertial filter. Also, multi-nozzle inertial filter was tested to find availability of inertial filter for various flow rate with simpler structure. We started preparation for marketing of the technology with private companies.
