Sullair is introducing its new ShopTek lubricated rotary screw air compressor, which the company said establishes new standards for continuous-duty compressors to meet the needs of small horsepower markets. The compressors are available in eight models ranging from 5 to 20 horsepower, with capacities from 17 to 78 acfm, and pressures from 125 to 175 psig. The new models operate at sound levels as low as 66 dBA, Sullair said.
