Every industry is now trying to protect [the invaluable earth] on a worldwide scale. Our industrial manufacturers are responsible for developing state of the art technology which is friendly to both humans and environment. Especially, restriction of VOC's (volatile organic compounds) and reduction of industrial waste have become imminent. Under this background, Japanese industries are expediting to meet with high transfer efficiency, little over spray, water base and low VOC paints. We introduced low pressure spray guns in 1990 to clear California regulations, the most stringent in the world, and have established new atomizing technology. Now we can offer the serialized [low pressure spray guns = LPH type] which have little over spray, high transfer efficiency and low atomizing pressure (at gun handle) to reduce over spray mist. It has resulted in satisfied painters who are environment-conscious; and [general purpose spray guns = W type] which have higher atomizing performance than previous models.
