Leybold presents dry screw vacuum pumps DRYVAC DV 500 and DV 800

Cologne, June 2021 – The new screw vacuum pumps DRYVAC DV 500 and DV
800 will be presented by Leybold in spring 2021. These vacuum pumps
compress completely dry, i.e. without operating lubricant in the compression
chamber and are therefore ideally suited as backing pumps in food packaging
or in pumping sets in heat treatment or coating systems, as they have
significant advantages over oil-lubricated piston or rotary vane vacuum
pumps.
