These compressors are designed to reduce energy use

Kaeser Compressors

The new SM 7.5, SM 10, SM 15, and SFC 8 rotary-screw compressors (photo) have been redesigned to reduce energy consumption, extend service life and improve operational performance. These models feature the new Sigma 06 airend, which is said to increase intake capacity when combined with IE4 motors on the 10- and 15-hp models to deliver up to 10% more flow than previous versions. The updated compressors also include a dual-flow fan combined with an external-facing cooler, resulting in approach temperatures as low as 7°F. This improves the effectiveness of downstream dryers and filters in removing contaminants that impact product quality and tool life. The die-cast, sickle-shaped blade of the dual-flow fan reduces noise and cools both the drive motor and the interior of the machine for greater reliability. A built-in web server and communication ports enable remote monitoring. The SFC 8 model features a separate drive cabinet with dedicated cooling to protect the frequency converter and maintain optimal operating temperatures. To reduce floor space and installation time, these models are also available with integrated dryers. — Kaeser Compressors, Inc., Fredericksburg, Va.
