Hitachi Sullair DSP 22 7 Bar 130CFM

Hitachi Sullair DSP 22 7 Bar 130CFM is a rugged oil-free screw air compressor designed for reliable, low-maintenance operation in demanding industrial environments. As a member of the DSP Series, this 7 barg unit delivers roughly 130 CFM of clean compressed air to keep tools and processes productive, with power and efficiency tuned for continuous duty.

The air end features stainless steel rotors in both stages, a patented PTFE-free rotor coating, and an internally coated rotor housing, delivering long life and high efficiency. A patented high pre-cooler design sits before the aftercooler on air‑cooled units to prevent thermal fatigue and boost durability. An integrated Motorized Isolation Valve (MIV) and Oil Mist Remover (OMR) protect the package from downstream moisture and oil mist, saving maintenance and helping maintain a cleaner production environment.

Capacity control includes a fixed-speed spool-type design and a variable-speed drive with two-speed reduction, engineered to keep specific power in the efficient range. The system reduces power consumption at no-load by up to 30% versus fixed-speed equivalents, delivering meaningful savings at light loads. The DSP22 uses Hitachi IE3 TEFC IP55 motors, integrated inverters, VSD fans on applicable models, and standard phase monitoring for reliable operation. A three-year warranty is provided when serviced with genuine DSP parts.
