DSVac11 Dry Screw 11.7 CFM Full Chemical-Resistant Vacuum Pump

Industrial-Grade Performance for Demanding Applications

The Across International DSVac Series Dry Screw Vacuum Pump delivers superior performance for critical scientific and industrial processes requiring oil-free, contamination-free vacuum environments. This advanced system utilizes two precision-engineered intermeshing screws that rotate in opposite directions without touching each other or the pump housing, compressing and moving gas from inlet to exhaust without any liquid lubricant or sealant in contact with the process gas. With 11.7 CFM pumping capacity and the ability to achieve vacuum levels down to 10⁻³ mbar or lower, this pump excels in demanding applications including plasma physics research, freeze drying, vacuum oven operations, thin film deposition, electron microscopy, and mass spectrometry. The dry screw design minimizes wear while maintaining process cleanliness, making it ideal for chemical processing, pharmaceuticals, semiconductor manufacturing, and any application where oil contamination must be completely eliminated.

Unmatched Durability and Continuous Operation Capability

Unlike traditional diaphragm pumps limited to rough vacuum applications, the DSVac Series offers substantially higher pumping speeds with greater throughput, handling larger gas volumes essential for continuous large-scale operations. The robust construction excels at managing corrosive, dusty, or condensable gases without the degradation issues associated with liquid-sealed systems, while the screw mechanism provides smooth, pulsation-free gas flow critical for processes requiring stable vacuum conditions. Built for 24/7 industrial use with minimal downtime, this full chemical-resistant system delivers the high vacuum levels, high flow rates, and durability needed for tough industrial environments. The precision timing gears ensure the screws never contact each other or the housing, virtually eliminating wear while maintaining consistent performance over extended operational periods—advantages that position dry screw technology as the superior choice for demanding continuous-duty applications where diaphragm pumps would require frequent maintenance or replacement.
