The R 5 RA 0750 A is one of the proven series of Busch rotary vane vacuum pumps. Its performance characteristics make it the perfect choice for medium vacuum use. When combined with a vacuum booster it is also ideally suited to high vacuum applications.

Robustness and reliability of operation
are the outstanding properties of R 5 rotary vane vacuum pumps. These are some of the reasons why proven Busch technology has long been established as the industry standard. Over 2.5 million R 5 vacuum pumps are in use worldwide in industrial day to day business.

Optimised for medium and high vacuum applications
The 50 Hz version of the R 5 RA 0750 A is equipped with a frequency converter that allows continuous operation at 60 Hz. This feature improves both pumping speed and ultimate pressure, although the energy consumption remains similar to that of a normal 50 Hz model. A version with a 60 Hz motor as standard is also available.

The thermal stability of these high-performance vacuum pumps is maintained by a special cooling system.

The robust frame and small flange connector allow vacuum booster to be installed directly. This compact arrangement increases pumping speed and permits operation in high vacuum ranges.

The R 5 RA 0750 A is ideally suited to applications in heat treatment and various coating and metallurgical processes, both as a single unit or as part of a vacuum system.
