Frameless Fans

Frameless Fans

The perfect partner for space-constrained and noise-sensitive applications.

With Delta Frameless Fans, cost-saving opportunities multiply, and innovative thermal solution designs become achievable. By removing the fan frame, engineers can directly integrate the fan into their designs. Traditional fans feature a housing around the impeller and motor, which works well for many applications. However, space-constrained projects often demand more creative integration.

The Delta Frameless Fan Series is the solution. It reduces material usage, weight, and overall costs—while maintaining the high performance expected from Delta’s industry-leading fans. Available in Blower (centrifugal), Mixed Flow, and Axial models, the Delta Frameless Fan Series offers a fit for virtually any project.

 

Benefits of Frameless Fans:

•   Cost-effective designs

•   Reduced noise

•   Perfect for space-constrained applications

•   Lightweight compared to traditional framed fans

Example Applications

Designs that incorporate a fan-integrated heatsink and allow for a larger open space may benefit from an axial frameless fan model.
For applications with limited space but no fixed air outlet (i.e., multiple air outlets), mixed flow or axial frameless models are recommended.
In contrast, designs with a fixed airflow direction and defined housing will benefit most from blower-type frameless fan models.
