for HIGH VACUUM
INew V_encO M y v a c U i l is specially processed to assure maximum vacuum pumping speed at low pressures when using Cenco and other mechanical vacuum pumps. It is the result of exhaustive tests made in the Cenco laboratories on the physical properties of a wide variety of vacuum-pump oils. Data taken from these tests show an increase in pumping speed of more than 10% over that obtained from the former Cenco Hyvac Oil, and as much as 35% over that obtained from other oils offered for vacuum pump use. Obtain maximum pumping speed at low pressures in your newer models of Cenco Hypervac-20, Cenco Magavac, Cenco Hyvac and other vacuum pumps by specifying the new Cenco Hyvac Oil, No. 93050B Cenco Hyvac Oil in quart glass bottle No. 93050C Cenco Hyvac Oil in gallon can
