Listen "Axial vs. Centrifugal Fans"
Episode Synopsis
Today we’re diving into one of the most essential questions in ventilation technology:
Axial fan or centrifugal fan -
when should you use which fan?
Whether you're an engineer, system designer, or decision-maker, choosing the right fan type can have a massive impact on energy efficiency, longevity, and operational costs.
We start by breaking down the technical and functional differences between the two fan types:
Axial Fans
Air moves parallel to the shaft, delivering high airflow at low pressure. Axial fans shine in open environments with minimal resistance - perfect for refrigeration units, heat pumps or greenhouse ventilation.
Centrifugal Fans
Air exits at a 90-degree angle to the axis. These fans generate significantly higher pressure, making them ideal for ductwork, filters, extraction systems, or smoke exhaust.
So how do you choose?
We walk you through practical decision criteria:
Do you need high volume or high pressure?
Are ducts and filters part of your system?
Is space a limiting factor?
How important is noise control?
With real-life examples, we help you answer the key question: Which fan will optimize my system’s performance?
We also touch on future trends - smart controls, energy-efficient EC-motors, and IoT integration that are revolutionizing the way modern ventilation systems operate.
Key Takeaways:
Use axial fans for high airflow in open systems with low resistance.
Choose centrifugal fans when higher pressure is needed to overcome resistance.
EC-motors are transforming efficiency and controllability in both fan types.
Next episode sneak peek:
We’ll explore EC- vs. AC-motors and how modern drive technologies are reshaping ventilation system performance.
