Particulate Respirators

KOKEN's Mighty Micron Filter series


KOKEN's "Micron Filter", an innovative electrostatic filter, provides a remarkably high particulate filtering efficiency, and a large capacity to hold particulates. With our unique plasticization technology to build up static electricity to wool based material, a challenging trade-off subject such as "high particulate filtering efficiency, low breathing resistance and long service life" have been attained. Moreover, besides using the electrostatic filtering, the mechanical filtering capability utilizing clogged particulate is also taken into our design to obtain the best overall performance against mist, oil mist and fume in welding operation.

Alpha-Ring Filters series
The more the fiber density of mechanical filter is high, the higher particulate filtering efficiency is obtained. Here, it becomes important to maintain the inhalation resistance as low as possible. By folding large mechanical filter up compactly in the shape of a concentric circle, the Alpha-Ring filter has solved trade-off subject such as "high particulate filtering efficiency and low inhalation resistance". Since 1999, KOKEN has been supplying the Alpha-Ring Filters into the market.
