The NFAN02 fan assembly from ABB Bailey cools INFI 90 and Net 90 control cabinets through continuous forced airflow. Plant engineers install this assembly whenever thermal loads threaten sensitive control cards. Consequently, it maintains safe internal temperatures across densely packed module racks.

Functional Overview
This assembly draws DC power from the cabinet supply and drives a single axial fan. Therefore, it moves heated air away from cards and power supplies. The NFAN02 also sends a tachometer signal so the system can detect fan failure. Meanwhile, its onboard energy storage smooths current spikes during startup and speed changes.
Installation and Handling Notes
Always disconnect cabinet power before mounting the NFAN02 onto a chassis bracket. In addition, verify airflow direction matches your cabinet ventilation design. Clean fan blades and guards on a regular maintenance schedule. Finally, confirm tachometer feedback after every replacement.
