Inline Centrifugal & Mixed Flow Fans — High‑Performance Duct Ventilation Solutions
HVACDirect.com has an impressive selection of inline centrifugal fans from Vents-US, Ruck, and Fantech. Some are built with corrosion-resistant materials, including a few models that are rated for corrosive air and radon gas mitigation. Centrifugal inline fans do not have to be round. Sometimes, the ductwork makes it more feasible to install a square or rectangular fan, but the airflow is still centrifugal in nature.
The determining factor between what would work best for your environment - centrifugal or mixed flow - depends greatly on the ductwork and the type of activity that occurs in the room or area. Mixed flow fans work best when connected to straight runs of ductwork, so if the existing ductwork has a lot of right-angle turns in it, an inline centrifugal fan might be the best choice. For rooms or areas with a lot of "heavy" air (saturated with moisture, fumes, and/or allergens), a mixed flow fan might be best.

These fans are installed directly inside ductwork to help move air efficiently through a ventilation system. Centrifugal fans use a spinning wheel to push air outward, while mixed flow fans combine features of axial and centrifugal designs to deliver a good balance of airflow and pressure.
A mixed flow fan offers a middle ground. It produces higher pressure than a basic axial fan while providing smoother and more consistent airflow than many centrifugal fans. This makes it a flexible choice for longer duct runs or tighter spaces.
They are very energy efficient. When installed in the duct and properly sized, they move air effectively without wasting power, often using less energy than older or poorly matched ventilation systems.
These fans are built for durability and steady performance. With correct installation and basic maintenance, they can operate daily for many years with minimal problems.
