Tailored for precision-driven chemical tasks, this Pumping Unit falls under the category of Chemistry Vacuum Systems. Equipped with four heads and three stages, it offers a volumetric flow rate of 3.4 cubic meters per hour. This versatile unit is suitable for evacuating, condensing, and pumping gases and vapors, particularly when dealing with high vacuum requirements such as with high Boiling Point solvents. Common applications include rotary evaporators and drying cabinets. With a maximum pumping speed of 3.4 m³/h at 50 Hz and 2.2 m³/h at 60 Hz, this MD 4C NT + AK + EK model ensures efficient handling of various chemical processes.
