Air compressors and vacuum pumps generate air pressure or create an air vacuum for operating pneumatic equipment. Raptor Supplies offers a wide range of these compressor vacuum pumps from brands like Bel-Art-Scienceware, Champion, Chicago Pneumatic, Dayton, Dewalt, Elmo Rietschle and Fuji Electric. The vacuum pumps are ideal for vacuum packaging, degassing, die casting and refrigeration services. We also supply diaphragm compressor and vacuum pump combo units designed for delivering a continuous-duty performance; best suited for air and water sampling services. The piston air compressors / vacuum pumps deliver a consistent output pressure which makes them less susceptible to pulsation.
