OFS Series Oil Free Rotary Screw Air Compressors

CLASS 0 OIL FREE AIR PLUS ROTARY SCREW DEPENDABILITY

When air purity is critical – oil free air is essential. The Sullair OFS Series of air compressors utilizes proprietary rotary screw technology in providing 100% Class 0 oil free air. 

Unlike oil-flooded rotary screw compressors, Sullair OFS Series compressors introduce no oil into the compression stage. While maintaining the Sullair reputation for durable air ends, Sullair OFS Series compressors add specific elements to ensure 100% oil free operation.

  • Legendary Sullair Dry Screw Two-Stage Air End
  • Sullair WS Controller
  • Maximum Energy Efficiency and Operating Consistency 

Models vary by region. Please contact your Sullair sales representative for more details.
