The PosiTrap Vacuum Inlet Trap product line (photo) is designed to protect pumps in small production and R&D applications up to 50 ft3/min. The filter elements are available in a variety of specialized media that are easily changed to allow tailoring to different processes. The user-selectable elements remove corrosive and abrasive particles from the vacuum stream to protect vacuum pumps. The filter elements are positively sealed at both ends to prevent “blow-by” and come in 4- and 8-in.-dia. straight-through and right-angle models. Filter types include stainless-steel-and-copper gauze, molecular sieve, activated charcoal and pleated polypropylene. — MV Products Inc., Mass-Vac Division, North Billerica, Mass.
