Although compact, mixed-flow inline ducted fans have maximum airflow capacities of up to 6,062 CFM and can move large volumes of air in long ducting runs and spaces with complex layouts.
Popular brands of mixed-flow inline duct fans include Fantech, S&P, and Ruck Air Movement. Fantech offers the FKD Series w/EC Motor, a high-efficiency option that uses an electronically commutated motor to boost efficiency.
