Keep air moving in commercial and industrial facilities with this tubular, centrifugal blower. It can help to supply air in general clean air applications, and can also be used to exhaust fumes. Use in installations with straight-through airflow in ducted systems. The blower consists of continuously welded, steel housing with polyester gray coating. Inlet and outlet flanges help to provide added strength and rigidity. It also features a spark-resistant aluminum wheel and rub ring, qualifying as AMCA Type B spark resistant. Includes motor cover. For non-ducted installations, optional guards (available separately) can be attached to keep personnel and equipment protected. For ease of installation, eight mounting brackets are welded on the blower along with four mounting supports, providing a universal mounting system.
