Commercial & Industrial Inline Duct Fans

For commercial and industrial facilities facing unique ventilation challenges—such as long duct runs or tight installation spaces—industrial inline duct fans offer an ideal solution. Installed directly within ductwork, these fans save space while delivering high volumes of airflow. Efficient, quiet, and versatile, inline duct fans are available in a range of sizes and performance levels to match your exact requirements. Whether you need to improve airflow, manage temperature, or control humidity, NorthStock’s lineup of premium HVAC inline fans has you covered.

Types of Industrial Inline Duct Fans

Inline Cabinet Fans

Quiet, enclosed fans ideal for offices, schools, and cleanrooms; customizable with filter housings, insulation, and enclosed motors. 

Dryer Booster Fans

Boost airflow in long commercial dryer ducts to save energy, reduce drying times, and minimize lint buildup in laundry facilities. 

Mixed Flow Duct Fans

Hybrid axial/centrifugal design delivering high airflow at moderate pressures; perfect for server rooms and hospitals. 

Radon Fans

Specialized fans for removing radon gas from beneath buildings, essential for mitigation systems in high-risk areas. This may be especially important if you live in an area identified by the EPA as having the potential for elevated indoor radon levels, including North Dakota, Ohio, Montana, Maine, and more, but it's important to note that there is no known safe level of radon exposure

Square Inline Centrifugal Duct Fans

Compact and easy to mount, square inline centrifugal duct fans are used where space is limited. Removable access doors make maintenance simpler. Centrifugal fans in general are especially efficient, making them ideal for large systems. 

Tubeaxial Duct Fans

High-capacity fans for general and smoke ventilation in warehouses, factories, and parking garages. 

Tubular Centrifugal Duct Fans

Durable fans for long duct runs with high static pressure, ideal for restaurants, garages, and historic buildings. 

Use Cases for Commercial Duct Fans

Industrial inline fans are used across sectors—from retail and agriculture to food service and manufacturing—to improve ventilation, enhance air quality, and maintain safe working conditions. They are essential for:

  • Increasing airflow in large buildings
  • Removing fumes and exhaust in industrial facilities
  • Maintaining indoor air quality in commercial spaces
  • Supporting specialized environments like cleanrooms and server rooms
