The Dry Vacuum Unit Series is a meticulously selected set of units developed on the basis of our independently researched dry pumps, designed to enhance the evacuation speed. This unit consists of a claw-type dry vacuum pump and a Roots vacuum pump connected in series, combining the advantages of both pumps for a compact structure and reliable operation. Once the claw pump reaches below 0.09 MPa, the Roots vacuum pump is activated. Within this pressure range, the Roots pump can exert its maximum evacuation speed, raising the ultimate pressure by an order of magnitude, allowing for long-term stable vacuum maintenance and the ability to remove large quantities of condensable gases.

Dry vacuum units are used for: vacuum distillation, molecular distillation, vacuum drying, etc., in special working environments that require the extraction of alcohol, gasoline, water vapor, toxic gases, corrosive gases, and other substances.
