Tubular Centrifugal Duct Fans

Tubular centrifugal fans are a compact duct fan solution commonly used to move air in HVAC systems for industrial and commercial buildings. Their in-line design makes them perfect for tight spaces, while their ability to handle a wide range of airflow volumes and static pressures makes them a versatile ventilation solution for many applications. For reliable performance and reduced HVAC operating and maintenance costs, explore NorthStock’s selection of top-quality tubular centrifugal duct fans today.

Tubular Centrifugal Fans for Industrial & Commercial HVAC

Built for performance, durability, and quiet operation, tubular centrifugal fans outperform axial fans in many demanding applications. Their versatile, in-line design allows mounting at any angle and anywhere in the ductwork—perfect for crawl space venting, makeup air supply, and exhaust in a wide variety of environments.

Applications & Industries

Inline centrifugal fans are used anywhere consistent, reliable air movement is essential. Common applications include:

  • Data centers – cooling sensitive equipment
  • Hospital laboratories – maintaining air quality and safety
  • Industrial facilities – controlling humidity, moisture, and contaminants

From moisture control to fume exhaust, these fans offer reliable airflow solutions across industrial and commercial spaces.

Inline Centrifugal Fan FAQs

What’s the difference between tubular centrifugal and mixed-flow inline fans?

Tubular centrifugal fans move air in a radial direction via a centrifugal impeller, making them ideal for long duct runs and high static pressure. Mixed-flow fans use a hybrid impeller for more linear airflow and quieter operation at moderate pressure.

Which is better for high static pressure — axial or centrifugal?

Centrifugal fans generally handle higher static pressure better than axial fans, which are better for low-pressure, high-airflow needs.
