Busch R5 RA 0155 A Overview
The Busch R5 RA 0155 A is a key mid-to-large capacity model within Busch’s industry-standard R5 rotary vane series.
Built for continuous duty cycles, it delivers powerful volumetric displacement alongside impressive deep vacuum depth required by demanding production machinery.
The RA 0155 A is heavily specified in high-volume food packaging lines, industrial thermoforming, central plant vacuum systems, vacuum degassing, and material transfer systems demanding nominal pumping rates up to 150 m³/h.
Recirculating oil within the internal chamber ensures consistent lubrication, tight vane sealing, and efficient heat dissipation during long runs. Integrated discharge filters collect oil droplets, preserving clean exhaust air and returning oil back into the pump’s oil circuit.
Vacuum Pumps UK provides fast availability and competitive quotes when you need an authentic Busch R5 RA 0155 A replacement or expansion unit.
