AIR MOVEMENT

Moving air for indoor comfort, safety, health, and productivity as well as material handling.

Air movement products (fans and blowers) draw fresh, outdoor air into non-residential buildings; circulate air throughout; and exhaust stagnant, smoky, greasy, unpleasant, and contaminated air and fumes from a building. Blower products can move airborne light materials such as sawdust, wood chips, dust, and other fine particles.

Overhead HLVS Fans

The most innovative line of large, overhead fans engineered to provide energy-efficient air circulation and evaporative cooling in commercial and industrial spaces.

Damper Application Considerations for Laboratory Exhaust

Understanding damper design and applications in laboratory exhaust systems is critical to the success of the design, installation and control of the laboratory exhaust system.

George R. Rieveschl Hall University of Cincinnati

Install a laboratory exhaust system that effectively exhausts laboratory fumes out of the building and away from nearby homes and dormitories while minimizing energy usage.

Grand Canyon University College of Arts and Science Building

Grand Canyon University officials wanted a laboratory exhaust system that would be both effective at removing laboratory fumes and cost-effective to operate.
