1. A hard disk drive, comprising: a disk base with a disk wall including a first intake, a second intake off of said first intake, an outlet and an air filter configured to receive a first airflow from said first intake and suction created by a second airflow from said second intake to create a negative pressure across a trapping surface of said air filter opposite said outlet; a spindle motor mounted on said disk base and coupled to at least one disk to create at least one rotating disk surface to generate an airflow configured to enter said first intake to create said first airflow; a first disk damper mounted on said disk base near said disk and including an enclosing wall neighboring said air filter to encapsulate a flow chamber fed by said second airflow and said first airflow having crossed said trapping surface to create a third airflow through said outlet.
