  • 31 CFM airflow delivers focused component cooling

4 cm 24 V DC case fan

The ADDA 4028 measures 4 cm square and runs on a 24 V DC supply. Its double ball bearing design targets builders who need a compact airflow source for tight chassis or industrial enclosures.

Fits 4028 mounting pattern

The fan installs into any 4028 hole pattern and draws power from a 24 V rail, so the surrounding system must provide that voltage. No PWM or speed-control header is included, leaving fan-speed management to the builder’s own controller.
