Robustness and reliability of operation 
are the outstanding features of the R 5 rotary vane vacuum pumps. These are some of the reasons that proven Busch technology has long been established as the industry standard. Over 2.5 million R 5 vacuum pumps are in use worldwide in day to day industrial business. 
 
Reliable and cost effective 
The rotary vane technology has been continuously developed and optimized by Busch for over 50 years. With a focus on both economy and operational reliability, highperforming and energy-efficient drive units have resulted from this development. 
 
Application oriented 
The R 5 vacuum pumps are distinguished by high pumping speeds even in low pressure ranges resulting in quick pump-down times. High-quality rotor vanes guarantee long uptimes and the specially-designed air exhaust filters allow excellent oil separation. 
 
Easy to service 
Maintenance can easily be carried out by the operator. Aside from regular maintenance checks and oil and filter changes, no further maintenance is necessary. 
 
R 5 rotary vane vacuum pumps are known throughout the industry for modern and energy-efficient vacuum generation suitable for all kinds of applications – whether it is used intermittently or around the clock, you can rely on the R 5. 
 
The R 5 series includes many more models than described here. Specialized R 5 models are available for certain applications such as pumping very wet gases and vapors, or discharging oxygen or explosive gases.
