The CBS screw blower packages from Kaeser Compressors deliver 93 to 448 cfm and pressures up to 15 psig. The blowers feature the Sigma Profile air-end and high-efficiency gear-drive technology and are available in both STC (wye-delta start) and SFC (variable-frequency drive) for energy performance and reliability. The CBS blowers are shipped completely assembled with high-efficiency motors, inlet filters, silencers, integral starters/drive and a full complement of sensors. The fully soundproofed enclosure is designed so that maintenance access is in the front and process connections on are the back for space-saving side-by-side installation. 540-898-5500; www.kaeser.com
