For evacuating, evaporating and pumping out gases and vapours. Exceptional chemical and condensate resistance Very high delivery rate almost up to the very low end vacuum Particularly low end vacuum, even with open gas ballast valve Very quiet and low-vibration operation Application : vacuum concentrators, rotary evaporators and vacuum drying cabinets Vacuum system MD 4 series MD 4C NT +AK+EC For applications where pressure-side condensation of solvent vapours is desired. Suction-side separator (AK, glass with protective coating) keeps back particles and liquid droplets The pressure-side emission condenser (EC) is particularly effective and compact. It ensures almost complete recovery of solvents, enabling cost-effective re-use and actively contributing to environmental protection Delivery incl. suction-side separator and pressure-side emission condenser.
