Abstract
A filter device is used to capture a desired amount of material suspended in a liquid or gas. The device includes a planar filtermounted in a chamber defined by a body member having an upper body, a lower body, an inlet port, and an outlet port. The filter includes porous portionsand. Porous portionis centrally arranged and is more restrictive to flow than portion. The filter is designed such that upon portioncapturing a desired amount of material, a predetermined pressure change exists across the filter. The predetermined pressure change causes the filter to deform and conform against an inner surface of the upper body resulting in all suspension flowing through the apparatus to flow through the more restrictive second portion
