ABSTRACT:
The present invention is directed to a device (50) for providing filtration of air. The device includes a body (70) and a cover (72) with each having endless mating structure (76) and (78) which may be welded together thereby mechanically pinching a flat sheet filter media (74) and holding it in place. The cut edge of the filter media (74) is encapsulated. The filter media (74) is held outwardly from bottom (92) of body (70) by gussets (90) to provide sufficient area for air to pass through. Inlet openings (110) are provided between top (94) and endless mating structure (78) in a fashion which allows top (94) to be attached to a flat wall of a sealed housing of a type used for disk drive systems.
