Blauberg Axial Inline Fan 4" Intake/Exhaust Questions & Answers

Q: What fans can I use a fan speed controller with?

A: Our fan speed controller (ACSC) will work with brushless motors, such as the ones commonly used with inline centrifugal fans. Do not use with blowers, booster fans, etc.

Customer Reviews

A great lightweight fan for small spaces. Review by MicroGroer
This fan is great for small spaces. It has a really small profile and can fit pretty much anywhere. Power-wise I'd rate it a little better then your standard booster fan. It can definitely be used as a standalone fan for small areas pulling through light filtration.

The only negatives I've encountered from this fan was the noise. It's quiet for the amount of air it moves however it's definitely not quiet. I recommend coupling it with some added some duct bends and a booster; problem solved.
