Questions about this item

Will the ball bearing need replacement during the fan's service life?

The ball bearing is built for continuous operation and is not a user-serviceable part; the fan is replaced as a unit when airflow drops.

What limits sustained airflow at 24 V and 1.2 W?

The 4020 frame and fixed 1.2 W power draw set the maximum static pressure and airflow the motor can sustain continuously.
