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
