AJAX Engine compressors Ajax integral engine-compressors are gas compressors with built-in two cycle natural gas engine. The slow speed (440 rpm max), simplistic design mae this compressor highly reliable, reliable, low maintenance and easy to operate. Ajax is the compressor o! choice in its power range ("0#-$00 %&) and it is common to see se'eral Ajax machines in one compressor station. tandard !eatures include
