RBS
RBS is the new innovative positive displacement rotary blower especially designed for application in ROBOX package. The blower fits special profile three lobes rotors which, together with a new design of the Low Pulse system, reduce residual pulsations of the conveyed gas below the 2% of operating pressure. Oversized shafts allow higher working pressure and higher rotation speed. Reinforced bearings and in particular the drive shaft one, positioned closer to the rotor in order to cope with V-belt drive loads.

Bearings
Roller bearings are used, selected for B 10 life of at least 50.000 hours under the heaviest operating condition.
Gears
Helycal teeth gears are used, with hardened and ground surface assuring a runing life close to bearings one. Gears are oil press drive non taper shafts.
Seals
Sealing of the conveyed gas is assured by labyrinth seal ont he shaft integrated with oil slinger. These seals ensure that the gas is conveyed oil free asuring proper operation for long life since without wearing parts. To convey special gas , blowers with special seals ( TM-V / PR-v ) can be supplied. The drive shaft is sealed by a lip seal, but for special applications it is possible to install mechanical seals (TMS).
Lubrication
Bearings and gears are lubricated by the oil splashed trough disk fitted on shafts.
Cooling
The blower and lubrication oil are cooled by natural convection up to outlet gas temperature Of 150 °C, beyond this temperature and up to 160 °C the cooled version (/R-V) with oil – water heat exchanger is available. Any other cas e please consult with Robuschi or dealer.
