Dry Roots Type Vacuum Pumps

Dry Roots Type Vacuum Pumps

Dry Vacuum Pump Meets Your Environmental and Energy-saving Needs
Unlike oil-ring or water-ring vacuum pumps, these dry multi-stage vacuum pumps use neither oil nor water. These unique dry pumps have attracted attention throughout the industry.

Features of Anlet Dry Vacuum Roots Type Pumps

  1. Easy maintenance and inspection facilitated by upper and lower split casing design.

  2. The multi-stage rotor is formed from a combined rotor and shaft assembly and is able to achieve strong vacuums down to 0.1 Pa.

  3. Using three-lobe roots type rotors, the pump achieves low noise and vibration with properly balanced rotor motion.

  4. No lubricants are required in the pump chamber -- because there is no oil backwash towards the high vacuum side, you get a clean vacuum.

  5. The shaft is sealed with a dry seal.

  6. No oil mist is discharged from the pump; this minimizes both environmental impact and health risks to the pump operator.

  7. Operation can begin from atmospheric pressure and performance remains stable over a broad range of pressures.

  8. Because no wear occurs, continuous long-term operation is possible and maintenance is also easy.

  9. Gas condensate can be drained and recovered.

  10. The simple design gives you outstanding durability.

Examples of Usage of Dry Roots Type Vacuum Pumps

In Vacuum Desiccation
Organic chlorofluorocarbon solvents such as Freon and trichloroethanes can no longer be used in steam cleaning processes because of the risk they pose to the ozone layer. Degreasing is now commonly carried out using greener hydrocarbon or water-based solvents, and multi-stage roots type vacuum pumps are used for drying parts after washing.
In Vacuum Distillation
Vacuum distillation can separate mixed substances into their components at low temperatures. Dry roots type vacuum pumps enjoy wide use in the manufacturing equipment for foodstuffs, pharmaceuticals, vitamins, and more.
In Vacuum Packing
Oil-free dry roots type vacuum pumps are popular in vacuum-packing processes for vegetables, meats, and other fresh food items. Dry roots type vacuum pumps are also used to vacuum-pack precision components, antioxidation parts, and other such items.
