Inverter Oil Free Screw Air Compressor�
Nirvana �90-160 kW
Our rotary screw air compressors reach their full potential through unmatched rotor profile accuracy and repeatability.
and repeatability, offering potential for fixed and variable speed oil-free compressors. Reliability is further enhanced by 4-point ball and cylindrical roller bearings, which do not require additional thrust management. Available with leading HPM� technology, it provides unmatched efficiency across the entire rev-drop range, unlimited starts and stops, and less power at start-up.

Durable Compression Module
• High-efficiency double-helix two-stage compression module, cast iron housing, synchronous gear drive
• In the past, oil-free screw compressors were equipped with balance pistons to offset the axial thrust, but the balance pistons were easily stuck due to dust and other pollution. In order to eliminate this hidden danger, Ingersoll Rand's oil-free screw compressors added ㇐ The thrust bearing replaces the balance piston to bear the axial force and improves the reliability of the main engine operation
• Super-coated rotors for stable, long-lasting performance
• The second stage rotor is designed with stainless steel, which is suitable for high temperature operating environment and greatly increases the life of the rotor

HPM Hybrid Permanent Magnet Motor
The stator coil and permanent magnet rotor of the hybrid permanent magnet motor will generate a strong electromagnetic force, which drives the motor shaft to rotate at different speeds. It eliminates the use of wearing parts and motor bearings in the motor (no gears/bearings/shaft seals, etc.), reduces the consumption volume of wearing parts to one third of that of ordinary motors, and facilitates on-site maintenance. One of the winding coils can be replaced directly, resulting in significant savings compared to the need to replace the entire winding in conventional motors.
