Advantages

Durability -Performance - Maximum Vacuum

The RB-DV series consists of 3 lobe rotary blowers used as exhausters which makes it possible to reach a high compression ratio. This is accomplished by a patented atmospheric air injection device that reduces overheating of the gas and the energy absorbed by the blower.

The main characteristics of these blowers are as follows:

• Maximum vacuum 93% - 28’’ Hg on a dead head

• Gases and vapours can be handled

• No sliding parts, therefore, no wear

• Safe operation and minimum maintenance

• No oil mists

• Atex 2 version available

The Vacuum Blower Package

The Robox Lobe DV is an integrated package designed to operate in a vacuum. It is able to reach up to 100 mbar(a) and deliver flow up to 10,500 m3/h.
