Rogers Machinery presented the Kobelco oil-free rotary screw KNW Series and announced the new K Series line of lubricated rotary screw air compressors and vacuum pumps.  The K Series is designed, assembled and manufactured in the Centralia, Washington plant, which has broken ground on a significant expansion to support this product line.  All K Series compressors come in both variable and fixed speed options. They offer a line of 40 to 350 hp single-stage rotary screws in highly customizable open frame (K/KV Series) and enclosed units (KR/KRV).  They also offer a standard single-stage 10 to 100 hp product line (KI/KIV). Lastly, Rogers now offers a line of two-stage rotary screw air compressors from 100 to 500 hp without enclosures (K2/K2V) and with enclosures (KR2/KR2V).  Rounding out the line is their new 20 to 250 hp KRVP Series single-stage rotary screw vacuum pump line.

Kaishan Compressors, China’s largest rotary screw air compressor manufacturer, has officially landed in the U.S.. They claim to be the third largest manufacturer of rotary screw air compressors, by unit volume, in the world.  They have established their U.S. headquarters just outside Mobile, Alabama. Sales Manager Dave George told me their Phase 1 product introduction is of 7.5 to 500 horsepower rotary screw air compressors. The units are single-stage or two-stage with VSD as an option along with a lifetime airend warranty.
