Model: 2512 Series

With fewer moving parts and smooth rotary motion, screw compressors provide reliable, nonpulsating positive displacement compression. Paired male and female helically profiled rotors are machined with extreme accuracy of pitch and thread form, to obtain tight uniform clearances. This ensures proper sealing and dynamic balance necessary for quiet and efficient performance. Positive displacement compression results in stable operation at partial or full load. A builtin separator (MSC only) creates a full selfcontained unit.

All of our products are engineering with the highest attention to detail. Whether choosing a standard model or one specially engineered, we provide needed features and benefits. With this philosophy, Hartford Compressors Inc. proudly presents the LSC which illustrates all aspects of engineering excellence.
