Hitachi DSP-55A6N is a 75 HP (55 kW) oil-free two-stage rotary screw compressor producing approximately 247 ACFM at 100 PSI, with stainless-steel screw airends and an intercooler between stages. The Hitachi DSP series is the company’s oil-free rotary-screw platform (not a scroll machine); two-stage compression with intercooling improves specific power and supports higher discharge pressures within the family. The package is ISO 8573-1 Class 0 certified for oil-free air and includes a PLC controller, integrated aftercooler, and electronic auto-drain; sound is approximately 70 dBA. Sized for pharmaceutical fill operations, semiconductor support air systems, and food-and-beverage process air where oil-free certification combined with substantial flow is needed. Pricing is dealer-quote only.
