6 Max-Fan Pro Series 420 CFM

MSRP: $341.08





The new Pro Series is the next generation of Max Fan by Can-Filters. It boasts impressive performance upgrades compared to the original Max Fan with improved airflow up to 30% more than in previous models, all while using as much as 15% less power.

A new fiberglass-composite housing affords a lighter fan while improving strength and reducing the whines, whizzes, and other noises commonly associated with running a fan. The new EZ Mount bracket makes installation a breeze while providing a sturdy connection for your fan.

Pro Series fans come with a built-in 3-speed selector and have undergone Commercial/Industrial certification by ETL to be listed as dependable for applications requiring permanent or overhead installations or continuous (24-hour) operation.

Max-Fan Pro Series fans are capable of even stronger and more efficient performance than the original Max-Fan. Manufactured in Germany (like the original Max-Fans), the Pro Series has a much more robust housing due to the fiberglass-reinforced plastic compounds, which meet all of the UL and CSA requirements. Aerodynamically optimized laminar airflow and extremely high efficiency set the Pro series in a class of its own.
