Inline Centrifugal & Mixed Flow Fans — High‑Performance Duct Ventilation Solutions

Buy your Duct Axial Inline Fans here at HVACDirect.com

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.

Benefits of Installing Inline Centrifugal & Mixed Flow Fans

  • Strong Airflow in Challenging Duct Runs: Moves high volumes of air through long or complex duct layouts where other fans may struggle.
  • Improved Indoor Air Quality: Efficiently removes stale air, humidity, odors, and contaminants from bathrooms, kitchens, labs, and production areas.
  • Enhanced HVAC System Support: Distributes supply and exhaust air evenly, reducing load on main HVAC units and improving overall system efficiency.
  • Lower Operating Noise: Mixed flow designs reduce turbulence and vibration, delivering quieter airflow for occupied spaces.
  • Durable Construction for Continuous Use: Industrial-grade materials ensure reliable performance in commercial and industrial environments.
  • Flexible Installation Options: Available in various sizes and configurations to fit diverse duct diameters and system layouts.
  • Energy-Smart Performance: Optimized design and balanced impellers reduce power consumption while maintaining high airflow.
  • Versatile Applications: Suitable for commercial buildings, industrial facilities, workshops, labs, retail spaces, and more.

Frequently Asked Questions

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.
