Oil Separator Tank

Ingersoll Rand OEM Solutions proudly introduces the ST35-30 Oil Separator Tank, designed for high-pressure, high-flow compressor systems in the most demanding industries, including mining, construction, and geothermal drilling. Built for reliability and efficiency, this tank sets new benchmarks in oil separation technology.

Unmatched Performance

 

  • Maximum Airflow Capacity: Up to 30 m³/min (1,000 cfm) 
  • Maximum Pressure: 35 barg
  • Supreme Oil Separation: Achieve oil carryover as low as 3 mg/m³ (0.003 ppm), reducing premature oil refills and ensuring clean, efficient operation.

 

Smart Design for Easy Maintenance 

 

The ST35-30 is equipped with three oil separator elements, each weighing only 1.5 kg (3.3 lbs), and a lightweight lid of 15 kg (33 lbs). No lifting tools are required, making field service fast and hassle-free. Compact design and lightweight components minimize downtime and simplify maintenance. 

Optimized Weight and Space Efficiency 

 

With an operating weight of 367 kg (809 lbs) including 65 liters (17.2 US gallons) of compressor oil, the ST35-30 is lighter than competing models—delivering significant benefits in assembly logistics and drill rig frame design. Its compact footprint saves space without compromising performance. 

Designed for CF1000H Air End 

 

Engineered to work seamlessly with the CF1000H air end, this oil separator tank ensures peak performance and reliability across all operating conditions.
