ABSTRACT:
An in-line vacuum filter normally mounted between a vacuum pump and a vacuum packaging machine to block flow of process debris and sediment that collects at the outer surface of an outer screen of two concentric contiguous cylindrical screen with air flow inward through the two screens. The outer screen surface is viewable from the exterior of the vacuum filter through a transparent outer cylindrical enclosure so that a machine operator can easily see when it is time to disassemble and clean the filter of the sediment and debris buildup thereon. The transparent outer cylindrical enclosure and the two concentric cylindrical screens are held in the assembled vacuum filter between a bottom filter plate and a top filter plate all held together by one rod threaded on both ends with the top threaded into the top filter plate and the bottom extended through the bottom filter plate with a hex nut threaded on the bottom. "O" ring seals are mounted in annular grooves of both the bottom and top filter plates in position to seal space between groove edges and the inside of the transparent outer cylinder enclosure at opposite ends thereof when a vacuum is drawn in the filter.
