S-energy lubricated rotary screw air compressors from Sullair can significantly reduce operating and energy costs over the entire life cycle due to a number of factors: the unit’s air end with a low-restriction inlet valve, a premium efficient drive motor design, and a low-pressure drop air-fluid separation system to prevent energy loss. Units offer high performance with low energy usage. They are available from 40 to 100 hp and 100 to 175 psi, and optional variable-speed drive units offer maximum efficiency and operating consistency. Units are easily installed, and their compact design makes routine maintenance easy. 800/785-5247; www.sullair.com.
