With IPC Industries' introduction of the latest Huskie breaker series,an increase in power for some models is attributed to a redesign of the operating piston, main valve and internal porting. In addition, the low-pressure nitrogen gas charge has been slightly increased. Each Huskie breaker employs a "gas-assist" operating cycle that uses the hydraulic system to provide most of the power. The low-pressure gas charge helps control recoil and hose surge without the need for a second accumulator.
