Features and Benefits

Unique Housing Construction

  • Removable end-covers permit easy access to timing gears, seals and bearings.

Quiet Helical Timing Gears

  • Synchronized rotors with close clearances enhance long life.
  • Timing gears transmit only a tenth of the driver power, resulting in negligible wear.

Lubricant-free Compression

  • No oil contamination of air or gas being compressed.

Positive Displacement Compressor

  • Operates over a wide range of pressures and speeds.
  • Handles a multitude of gases from air to light hydrocarbons, ammonia, freon, hydrogen and nitrogen.
  • Permits operation at moderate speeds, suitable for direct-connected motor drive.

Less Area Required for Capacity Range

  • May cut floor space costs substantially.

No Unbalanced Forces

  • Eliminates need for expensive foundation, lowering installation costs.

Rotors Do Not Touch Each Other or the Casing

  • Actual compressing parts not subject to mechanical wear.
  • Power requirements are less than other types of oil-free compressors in its pressure range.
