  • Disk file employing dual filters
    Patent number: 4857087
    Abstract: A disk file 10 employs at least two filters 15,16 for removal of airborne particles, one filter 16 having a relatively coarse mesh and a relatively high rate of airflow and the other 15 having a relatively fine mesh and a relatively low rate of airflow. The fine filter 15 may be combined with a third, breather filter 30 which removes particles from air entering the disk enclosure. The main purpose of the coarse filter 16 is to remove the larger, more damaging particles very rapidly, thereby reducing the risk of damage to the surfaces of the disks 12.
