Spindles - Lingering Questions

Air would be simpler to implement/setup, but I am concerned about how much debris will be drawn into the spindle by the fan. Will I be tearing it apart every n hours to clean it?
Is keeping it clean as simple as blowing some air through it periodically? I doubt that.

The air intake is at the top of the spindle - a very long way from where the cutting is going on. I always run dust collection - so dust at the top of the spindle is not a concern for me.
