The Robox Lobe, which is the Robuschi Positive Displacement Rotary Lobe Blower, is an integrated package designed to convey gas at low pressure. Based on the RBS lobe positive displacement rotary lobe blower, it is operated by an electric motor through a belt drive.

RBS is a positive displacement rotary blower with three special profile lobes that, combined with a low pulse system, reduce the residual pressure pulsation of the conveyed gas to less than 2% of the operating pressure. Thanks to new engineering technologies, the Robox unit includes all accessories and the ready-to-fit and exclusive SENTINEL electronic monitoring system. In addition the enhanced noise enclosure has been restyled and painted and provides improved noise level reduction.

Delivering reduced:

system costs thanks to the optimisation of space;
running costs thanks to the low energy consumption and to the exclusion of all standstill risks ensured by the innovative electronic control system SENTINEL;
maintenance costs thanks to the easy access to all parts for normal service operations.
