10 – 80 bar
CB · Compressor Booster Medium Pressure
The Nardi CB "Compressor Booster" Series are purpose-built for medium-pressure boosting, accepting inlet pressures from 50 to 650 mbar (0.725 to 9.4 psi) and delivering final pressures of 40, 60, and 80 bar (580, 870, or 1160 psi).
Two frame configurations are available: the C-frame (compact) and the M-frame (belt-driven), giving you flexibility across installation types, motor sizes, and power supplies. ATEX Zone II certification is available for use in potentially explosive atmospheres.
