New generation of SUNON fans bringing new opportunities (SOS electronic)


The generational exchange of SUNON’s DC compact axial fans brings new fans with lower power consumption and lower noise. The overall construction remains the same, and thus the transition is seamless. Find the new generation in SOS electronic stock.

Couple of years ago, the traditional fan manufacturer SUNON began the process of generational exchange in the “DC compact axial fans” category. And we still did not reach the end. There are several hundreds of types of fans to be replaced.

The visual comparison won’t bring significant differences:
  • Small details on the frame 
  • Small details on the arms holding the rotor
  • Minor changes to the construction of the blades
  • The overall construction (mounting, wiring) is the same, so the transition to new types is seamless.
However, performance changes are way more important:
  • For all types, the power consumption decreased significantly
  • Noise – the most of types are quieter, few types are equally noisy as before 
  • The airflow and pressure are higher in most cases, some models without change 
  • Speed – here you can find all possibilities – remained unchanged, slightly increased or slightly decreased

The manufacturer has achieved significant performance changes with minimal visual changes:

One generational exchange already happened earlier and was also associated with a radical change of Part Numbering. This time, we only need number “1” which was added to the marking.

This red 1 stands for the new generation. Find the whole Part Numbering System here.

The following table shows an example of one new series of fans with VAPO and one with Sleeve bearings:

Previous-generation fans are only available while the stocks last. Find the selected new generation products directly in our stock range, others are available upon order.
