This helps to blow away smoke, ash and impurities from the laser beam, which makes the laser more effective and repeatable.  It also keep debris generated from the cutting/engraving process away from your laser lens.  When working with wood, air assist also makes the cutting or engraving of the laser beam more effective, because it speeds up the burning effect caused be the laser.  This is definitely a good addition to any laser cutter or engraver.
