AUP’s worldwide headquarters is in San Leandro, California in a 120,000 square foot building that houses one of the most innovative and technologically advanced life-support equipment manufacturing facilities in the world. AUP’s team of engineers, product designers, and manufacturing experts are dedicated to the philosophy of excellence. One distinguishing attribute that separates AUP from other manufacturers is the commitment to vertical integration. The vast majority of AUP products are designed, developed, manufactured, and tested in its own facilities. NO other dive company can make that statement.
