SSR Two-Stage 100-500 HP
Looking for a highly energy efficient and reliable air compressor? Then look no further than Ingersoll-Rand's SSR 2-stage series of compressors. With our integral gear drive system, digital control system, and 8,000 hour coolant, the SSR 2-stage is a compressor that you can count on for years to come.

SSR UltraCoolant
Designed specifically for rotary screw air compressors, UltraCoolant minimizes maintenance costs by maximizing the time between changes: 8,000 hours or 2 years.

Higher Ambient Rating
The SSR operates easily in ambient temperatures up to 115° F (46° C), even the motor. This means fewer nuisance shutdowns due to summer heat or dirty coolers.

Reduced Bearing Load
A lower compression ratio in each stage leads to reduced bearing loads and longer airend life.

Energy Efficient Airend
At the heart of the compressor is our time-proven 2-stage airend. By compressing the air in two steps instead of one, energy savings of up to 15% are realized.

Digital Control System
Capacity control of the compressor is regulated by the Intellisys microprocessor controller and an electric stepper motor. Since there are no pressure switches to adjust and very few moving parts, the SSR 2-stage can maintain plant air pressure without constant attention.
