The Q-VDF series adjustable flow tubes are air-powered vacuum pumps featuring a straight-through design that allows debris to pass directly through without clogging. It was engineered for dusty applications, providing a combination of high flow rates up to 120 scfm and vacuum levels of up to 25 inches Hg. They come in barrel I.D. sizes from 0.1 to 0.75 inch. They are ideal for handling a variety of products, such as wood, corrugated, concrete block, as well as powder-coated packaging materials, according to the company.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
