Industry Trends and Opinion

The demand for compact ventilation solutions is rising across HVAC and electronics sectors. Engineers are increasingly shifting from standard axial designs to external rotor centrifugal fans for their higher pressure capacity and integration flexibility.

AFL believes that fan customization is no longer a luxury—it’s a performance necessity. In the age of energy efficiency and design complexity, only tailored solutions deliver long-term ROI.

Do you agree? Are universal fans still viable for specialized equipment? Or has custom engineering become the standard?
