CHOOSING THE RIGHT COMPRESSOR Three-phase compressors are more efficient producers of compressed air than single-phase equivalent units, so where a three-phase supply is available the best option is thee-phase compressor. Wherever possible choose a larger compressor than you require at present to allow for expansion. Compressors with cast iron cylinders running slow, offer a much extended service life.
THREE PHASE Main electrical supply industry. 380/440 Volts Any size of compressor MAIN BENEFIT OF THREE PHASE Approx 2/3 cost saving over single phase Stable supply Longer motor life
