Air-cooled, positive displacement compression machines with twin shafts rotating synchronously in opposite directions. Gearbox located outside of the compression chamber allows compressed gas to be considered completely "Oil-free". Asymmetrical 4+3 screw section especially well adapted for low-pressure operation
Suction: gas enters compression chamber.
Compression: volume between rotors diminishes and the pressure increases.
Delivery: compression ratio is reached and the gas is discharged into the delivery pipe.

UltraCoat™ - energy savings and longer life
Rotor surfaces can deteriorate over time, making them increasingly susceptible to compressed air impurities and temperature fluctuation. This would lead to reduced efficiency, decreased air purity, and breakdowns.
Ingersoll Rand advanced rotor and housing protection UltraCoat™ ensures the most durable coating, with unmatched adhesion and temperature resistance.
Each Ingersoll Rand oil-free rotor and housing is especially prepared, to create a surface texture to which the UltraCoat™ micro-coating bonds with the tightest, longest-lasting grip possible.
Ultimately, UltraCoat™ delivers greater reliability in performance and air quality, rotor longevity, increased uptime, and reduced energy costs.
