THE PUMPING GROUP is the heart of a compressor and for this reason all ABAC / NUAIR groups are designed and manufactured to guarantee high performance, efficiency and reliability over time. There are many advantages that distinguish these groups:
– finned manifolds that ensure effective cooling of the air entering the tank;
– oversized oil covers for better lubrication; spheroidal cast iron shafts;
– connecting rods with special anti-wear treatment;
– multi-finned flywheels for better cooling of the pumping unit;
– reed valves in special steel.
