How to Choose the Right Industrial Centrifugal Fan for Your Application

13 10 月, 2025

💡 Introduction

Choosing the right centrifugal fan can significantly improve your system’s efficiency, stability, and energy savings. Whether you’re dealing with ventilation, fume extraction, or material conveying, proper fan selection is crucial.

1. Determine Your Airflow and Pressure Requirements

Start by defining air volume (m³/h) and pressure (Pa). These two factors dictate the fan’s impeller size and motor power.

2. Select the Right Type

Dajing offers a full range of industrial centrifugal fans, including 4-68, 4-72, 9-19, and GY4-73 series, designed for different pressure and flow scenarios.

3. Consider Efficiency and Noise

Look for models with aerodynamic impeller design and low-noise operation. Dajing fans use precision-balanced rotors to ensure stable performance.

Check Material and Coating

For corrosive or high-temperature environments, stainless steel or anti-corrosion coatings can extend service life.

5. Ask for Professional Support

Our engineers provide one-on-one selection support to help you find the perfect match for your working conditions.
