Sullair DSP Series Compressors

Sullair DSP Series Compressors

Oil Free Compression and Rotary Screw Dependability

30–300 hp • 22–240 kW

The DSP Series rotary screw air compressors are the perfect choice for applications requiring completely oil free air, including:

  • Pharmaceuticals
  • Food and beverage manufacturing
  • Electronics
  • High-technology manufacturing
  • Textile manufacturing
  • Robotics
  • Automotive
  • Paint

The roots of the DSP Series come from Hitachi — with thousands of successful oil free rotary screw compressor installations around the world today.

In many operations, compressed air comes into contact with items in the manufacturing process. When air purity is critical — oil free air is essential. Oil particulates in compressed air can contaminate downstream processes and production. Oil Free compressors eliminate potential contamination as no oil or lubricant is introduced into the air compression process. Reduced risk of contamination helps improve your business operations and profitability.

For applications in which air purity is essential, including pharmaceuticals, food and beverages, electronics, automotive painting, and textiles.

DSP Series compressors are certified oil free under ISO8573-1
