Typically, a vacuum system won't use a filter like you are looking for. They typically use a round filter in a canister housing, where air is drawn in from the side and exits from the center of the filter. The filters are much larger than the lines that are used for vacuum. The one in the .pdf you linked would be about 8" in diameter for a 2" line.
If you can fabricate a housing, an automotive air filter is an inexpensive option.
