The new SFC 11 rotary screw compressor combines our proprietary Sigma Profile airend, Sigma Control Basic system and state-of-the-art drive technology to offer 17 to 75 scfm in pressures to 217 psig. The SFC 11 features a space-saving cabinet and split-cooling air flow design for easier ducting and extremely low noise levels. Wide-opening access doors allow frontal access to all major components and significantly reduce access clearance and footprint.
