It features a compact and hygienic design, reduced heat emissions, and enables faster and easier maintenance. The optional Ecotorque variable speed drive provides up to 50% additional energy savings and a 20% increase in pumping speed. The accessory extends the supply voltage range supported by the vacuum pump, making it suitable for use in almost all countries around the world.

Compared to the previous R5 RA generation, the R5 RA 0520 A has a 20% smaller footprint, is 25% lower in height, and the absence of external piping improves leak tightness. The compact and hygienic design features surfaces that repel water and dirt. The total number of spare parts has been reduced by 40%, making maintenance fast and efficient, with all service-related parts located on one side. Heat emissions have also been decreased through an improved cooling system that combines optimal pump operating temperature with compact construction.

The new vacuum pump is made for continuous operation in the rough vacuum range with vacuum levels down to 0.1 hPa (mbar). Field tests were successfully carried out to validate performance and reliability.
