Greater energy efficiency, greater output: this is the philosophy of the RA 0155 A. Thanks to a slightly modified design concept, the
RA 0155 A – representing the fifth generation of the proven R 5 series – delivers tangible improvements in energy efficiency.

Fast evacuation times
With the fastest evacuation times in its class, the RA 0155 A also offers the advantages which the R 5 is very well known for. As always, you can expect operational reliability and robustness as standard.

The RA 0155 A is the ideal vacuum generator for continuous operation in the low vacuum range, for pumping of large volumes and when working at ultimate pressure. This is ensured by the perfect oil separation which uses Busch exhaust filters developed in-house and the hardwearing Busch vanes made from special composites material.

Easy maintenance
The advantages also include easy maintenance, which can be carried out by the operator. Apart from changing the oil and replacing the filters at standard service intervals, no additional maintenance is required.

R 5 rotary vane vacuum pumps are well known in nearly all areas of industry for their economical vacuum generation – whether used intermittently or round the clock: you can rely on the R 5.

Special versions of the R 5 are available for special applications such as pumping of oxygen.
