ABSTRACT:
An improved filter pad assembly, for supporting a filter pad, used in conjunction with a filter system having a pumping unit to filter a contaminated fluid. Included in the filter pad assembly are a filter pad support member, a sealing member, and securing means for maintaining the filter pad support member and sealing member in a closed operative position during the filtering process such that a substantially fluid-tight seal is created therebetween. Thus, the contaminated fluid is prevented from exiting the filter pad assembly without passing through the filter pad. The filter pad assembly may be defined to include, or not include, the filter pad. The filter pad assembly and filter pad also have a one-way guided configuration that ensures the filter pad is properly oriented within the assembly. Three preferred embodiments of the filter pad assembly of the present invention are disclosed.
