Today we specialize in vacuum valves, vacuum chambers and vacuum hardware accessories. The two qualities that set GNB apart from our competition are our ability to make large products (if you can find a way to transport it, we have the equipment to build it) and our experience of successfully engineering products for the most difficult applications.
From a small garage shop type business to a 70,000 sq. ft. facility, GNB has a reputation of developing great products at reasonable prices. Our mission is to provide highly successful vacuum products for science and industry. Along the way, we have satisfied many customers, and we have participated in some remarkable scientific applications.
