DC Cooling Fans, Blowers and Centrifugal Fans

Q: How do I choose the correct frame size and speed?

Start with available mounting space, then compare airflow and static pressure at the system operating point. Electrical input and acoustic output should also be considered.

Four DC fan families for different cooling challenges

Axial fans move high volumes of air in a straight path. Blowers and centrifugal fans are better suited to ducting, filters and systems that require higher static pressure.

Technical FAQ

DC cooling fan selection questions

What is the difference between a DC axial fan and a DC blower?

An axial fan moves air parallel to its shaft and is typically selected for high-volume, low-to-moderate-pressure cooling. A blower turns the airflow through an outlet and is usually a better fit for focused airflow, ducts or more restrictive internal paths.

How do I choose the correct frame size and speed?

Start with the available mounting space, then compare the airflow and static-pressure requirement at your system operating point. Higher speed can increase cooling performance, but electrical input and acoustic output also need to be considered.

Which DC voltage and control options are available?

Availability depends on the fan series. Common requirements include multiple DC voltage options, PWM speed control, tachometer or alarm signals, custom leads and connectors. Send your preferred electrical specification with the RFQ.

Can July Fan support custom OEM cooling projects?

Yes. OEM discussions can cover performance targets, bearing systems, wiring, connectors, control functions, environmental protection and production-volume requirements.
