The goal was to transfer this process into an American production facility. In designing and building the chemical filling cleanrooms, Lasco Services integrated the Japanese specifications and experience with the best of American cleanroom technology to create a true state of the art chemical production facility. Lasco Services built the cleanrooms with locally obtained materials and easily replaceable components. The cleanrooms continue to exceed the customer's specifications and have been maintenance friendly facilities ever since.
