The compressors belonging to the range ROMA have fewer moving parts if compared to compressors of other brands (especially the two-stage dry ones), plus they run at very low speeds and with balanced loads on the bearings. As a consequence, they have a longer life and lower operating costs. The maximum flow temperature is about 60 °C. This determines a compression that is very close to the ideal one, that is to say isothermal.
The range ROMA has great advantages if compared to the traditional “oil-free” compression technology. As a matter of fact, it does not need oil nor an air/oil separator and, as a consequence, it has no transmission gears, no oil pump nor oil filters. In addition, the single screw compression with two satellites has balanced compression loads and, therefore, avoids excessive stresses on the bearings.
