The ABAC models are characterized by pumping units with cast iron cylinders and heads with large fins and final collectors for more effective cooling, which improves the volumetric efficiency of the compressor. They are also made with an oversized oil sump for better lubrication, crankshafts in spheroidal cast iron, reed valves in special stainless steel which allows high yields and very high resistance to wear and fatigue.
The B4900 model is the first model in the ABAC two-stage range, characterized by more powerful, quieter, safer groups, suitable for heavy-duty applications, designed for very high durations with low energy consumption;
In two – stage pumping groups the air is compressed in a first phase, cooled and then again compressed in a second phase, allowing to achieve very high yields.
