Atomizing Air Compressors for GE frame gas turbines
PILLER Atomizing Air Compressors are small high pressure air compressors that are used on GE Gas Turbines fired by liquid or dual fuels. These compressors take a small amount air off the final stage of the gas turbine air compressor section and then boost that air to a higher pressure. This higher pressure air is fed back to the liquid fuel nozzles to provide for more complete and efficient combustion. Over the years GE has equipped the turbines with either a Turbonetics SC-6AA or Atlas Copco SCF-6 Compressor. The PILLER A-Series compressor is a proven drop in replacement for those compressors, having successfully replaced more than 50 of the OEM supplied units.

Best alternative to the original equipped compressors
PILLER A-Series compressors are a drop-in replacement for Turbonetics or Atlas Copco SCF-6 compressors. A real alternative to the original equipped compressors: Only the highest quality parts are used, the impellers are 5-axis milled from aircraft quality precipitation hardened stainless steel, gearing is made to AGMA (American Gear Manufacturers Association) Q-13 quality and the inlet shrouds are CNC machined to match the impeller profile.
New A-Series Atomizing Air Compressors and PILLER Rebuilds of SC-6AA and SCF-6 compressors utilize the same precision high speed tilting pad journal bearing designed to ensure rotordynamic stability at compressor speeds in excess of 50100 rpm.
