LRS Series Rotary Screw Air Compressors

The Gardner Denver LRS Series Rotary Screw Compressors deliver all the proven reliability and versatility of the standard L Series, but with one major advantage — advanced variable speed drive technology. This intelligent drive system automatically adjusts the compressor’s motor speed to match real-time air demand, significantly reducing energy consumption during periods of low usage. As a result, the LRS Series provides remarkable operational efficiency, especially for facilities with fluctuating production cycles or varying shifts. Just like the L Series, the LRS lineup offers a broad power range from 10 to 400 HP, quiet enclosures on all models, and multiple installation options including base-mount, tank-mount, and integrated AirStation packages with dryers. This makes the LRS compressors suitable for almost any workspace, from small industrial shops to large-scale manufacturing plants. Where fixed-speed compressors run at full RPM regardless of air demand, the LRS Series stands out by lowering motor speed whenever possible, reducing wear, lowering operating temperatures, and extending equipment life. This not only saves electricity but also minimizes overall maintenance costs. Direct-gear and belt-driven configurations further enhance durability and long-term reliability. Ontario Compressor Supplies offers the LRS Series throughout Southwestern Ontario, helping businesses reduce energy bills while maintaining consistent, high-quality compressed air performance.
