Oil-Free Vacuum Pumps

Oil-Free Vacuum Pumps

Oil-free vacuum pumps, also known as dry vacuum pumps, operate without the need for any lubricating oil. These pumps are ideal for applications where contamination is unacceptable, or when dealing with gas mixtures that may react with oil.

Screw Dry Pumps

Screw dry pumps, also known as dry screw vacuum pumps, operate using two screw rotors rotating in opposite directions. This movement traps the gas between the cylinder and the screw chambers, compressing it until it's pushed out. These pumps are known for their efficiency, and they're commonly used in industries such as packaging, electronics, and coating technology.

Scroll Dry Pumps

Scroll dry pumps, or dry scroll vacuum pumps, operate using two spiral-shaped scrolls. One scroll is fixed, while the other orbits eccentrically without rotating. This movement traps gas in the crescent-shaped pocket formed by the scrolls and compresses it until it's pushed to the center and exhausted. Scroll dry pumps are known for their compact design and quiet operation, making them suitable for laboratory, semiconductor, and medical applications.

Please note that the specific models and applications of Baosi screw dry pumps and scroll dry pumps may vary. For detailed information, please refer to the manufacturer's official resources or product manuals.
