Strobic Air Corporation, a recognized technological leader in the air movement industry, specializes in technologically advanced exhaust systems for laboratory fume hoods in university, public health, government, chemical, pharmaceutical, industrial and other process industries. With more than four decades of experience in addressing the needs of laboratory researchers and facility owners, Strobic Air has continued to develop and enhance its Tri-Stack® Roof Exhaust systems to provide even greater flows, lower energy costs and decreased noise levels.

Makers of very noisy exhaust systems. I dont recommend the use of Strobic units if people live or work anywhere near the exhaust system. Rooftop stacks are less costly to install and maintain, and are quiet.
