COBRA Industry Dry Screw
COBRA NC- dry screw vacuum pumps are highly efficient for use in many industrial applications including process applications. These models represent many years of experience in dry vacuum technology and offer key design benefits: 
Reliable and robust - The variable pitch and free gas outlet greatly improve the pump’s ability to handle liquid and dust carry-over. The unique temperature distribution offers resistance to corrosion. The optimized efficiency reduces the thermal load, thus increasing pump service life. 
Easy to service -A simple, robust design and the ability to handle the vast majority of process gases ensures long service intervals and minimum maintenance downtime. 
Application-oriented -COBRA NC dry screw vacuum pumps can accommodate a number of applications due to the different versions available. The cooling water can be injected direct or radiator cooled. COBRA NC dry screw vacuum pumps are also available as ATEX versions.
