low power consumption, minimal maintenance, low operating costs
high particle and vapour tolerance, anti-corrosion on internals, inert lubricant
high pumping speed at all inlet pressures
Leak tight design:
no contamination of process gases, no leakage
< 68 dB(A)
COBRA NS screw vacuum pumps are high-performance and robust vacuum generators for processes where gases need to be pumped reliably and without contamination. Thanks to the dry screw technology, the compression chamber is completely free from operating fluids. This prevents condensation and deposits of the pumping medium and stops the medium from becoming contaminated with oil and allows process gas recovery.
Ultimate pumping speed
COBRA NS screw vacuum pumps are designed to achieve a high, stable pumping speed – even at normal working pressure range of 1 to 1000 hPa (mbar).
The integrated motor design makes this vacuum pump series leak tight. Optimum corrosion resistance is ensured thanks to temperature control and special coatings on the screw rotors. The outstanding levels of efficiency reduce the thermal demand and increase the life cycle.
COBRA NS screw vacuum pumps are especially designed for applications which require:
- hermetic vacuum supply
- clean vacuum
- inert lubricants
- quiet operation
- compact pump design
- full heat removal
- contamination-free operation
