Patrylo, Inc. completed the design and construction of this state of the art inhaler manufacturing facility for Gerresheimer Medical Plastics, USA, a world-class manufacturer of a variety of medical devices. Inhalers are manufactured and finally assembled in this plant for GSK. The facility expansion includes more than 82,000 square feet of newly finished space and is comprised of a new cleanroom, assembly area, material process quality control room, new changing and break areas for the plant, offices, and mold storage shop. The finished production space design criteria were demanding (Class 8) and required multistage pressure drops from manufacturing to packaging and finished goods, multiple air changes with HEPA filtration, and strict temperature and humidity control. Machine oil cooling was also provided. The novel approach required all injection molding machine utilities to be fed from above the floor to facilitate cleaning.
