The IBEX GS-series is comprised of 14 models, all equipped with a nitrogen accumulator and suitable for carriers from 0.8 to 55 tons. The larger models in the GS-series (1200 - 4000) feature an accumulator to generate additional impact energy. The accumulator also reduces peak pressures from the hydraulic circuit, reducing recoil to the carrier and protecting the breaker. When desired the breakers are available with an open housing, the GO-series (Gas Open).
