Vortex Powerfans are high-performance, inline duct blowers constructed from quality steel with heavy duty attractive hammertone powdered coat finish. The extended collar allows for easy duct installation and taping. Superior quality and smart design ensure vibration-free operation utilizing balanced motorized impellers with permanently lubricated ball bearings. Includes 6' power cord and galvanized mounting brackets, allowing both horizontal and vertical installation. 

Atmosphere's V-Series combines high performance and quiet operation. These fans are equipped with a mixed-flow impeller, allowing more air volume than any other comparable impeller design. Furthermore, the V-Series fans operate at lower RPM (1500 to 1700), making them even quieter. These fans are available in 12", 14", and 16" diameter.
