Product catalog summary
Introduction
The DSP Series Oil Free Rotary Screw Air Compressors, ranging from 30 to 300 hp (22 to 240 kW), are a collaboration between Sullair and Hitachi, combining over 100 years of compressor engineering experience. These compressors are designed to provide oil-free air, ensuring high-quality production standards.

Key Features
  • Oil Free Seal: Ensures the production of clean air, meeting ISO 8573-1 Class 0 standards for applications where air purity is critical.
  • Reliability, Durability, and Performance: Built to last with a focus on trust and efficiency, these compressors are designed for long-term use.
  • Applications: Suitable for industries such as pharmaceuticals, food and beverage, electronics, textiles, robotics, automotive, and paint.

Technical Specifications
The DSP Series offers both fixed and variable speed models, with specifications including:
  • Horsepower ranging from 30 to 300 hp.
  • Motor output from 22 to 240 kW.
  • Pressure ratings typically at 125 psi (8.6 barg).
  • Airflow capacities from 114 to 1303 cfm.

Innovative Design
  • Air End Design: Features a patented taper rotor design for efficiency, stainless steel coating for corrosion resistance, and a PTFE-free rotary coating for longevity.
  • Motorized Isolation Valve: Prevents condensate backflow when the compressor shuts off.
  • Oil Mist Remover: Recaptures gearcase oil mists, promoting a cleaner production environment.

Energy Efficiency
The DSP Series is designed to optimize energy efficiency with features such as:
  • VSD models with a patented no inlet valve design.
  • Fixed speed models with patented solenoid valves for energy savings.
  • High pre-cooler design to reduce moisture content in compressed air.

Additional Features
  • Phase monitor for electrical protection.
  • Noise-reducing package with full enclosure and vibration isolation.
  • Maintenance-friendly design with easy access to filters and external grease fittings.
  • Controller with LCD monitor and optional communication protocols like MODBUS and BACnet.

Conclusion
The DSP Series compressors are engineered for reliability and efficiency, making them ideal for industries requiring high-quality, oil-free compressed air.
