Oil Free Rotary Screw Air Compressors [ZW Series]

FS-Curtis, ZW-Series Oil Free Screw Air Compressors

Variable Speed Drive (VSD) 30HP/22kW ~ 160HP/120kW

FS-Curtis, ZW-Series Oil Free Screw Compressors produce true oil-free air, free of any hydrocarbon. Water cools, seals and lubricates the compressor.

ZW/ZWV Oil Free screw air compressors offer a completely integrated package. Clean lines and intelligent layout provides an unobstructed airflow that utilizes the chimney effect to provide even cooling with no hot spots even after the compressor has stopped. Intakes air from the coolest area eliminating air preheating.

Key to the ZW/ZWV is the most advanced oil-free air end in the industry. No complex seals or gear arrangements provide a simple and rugged reliable air end. Water sealing-nearly ideal (isothermal) compression gives improved efficiency, lower energy consumption. These low operating temperatures and low speeds provide long life and lower maintenance costs.

ZWV series use ABB standards and industrial inverter drives. Highly flexible AC drives can be configured to meet the precise needs of applications. ZWV can provide up to 35% savings compared to a standard compressor unit.

  • High Efficiency. Water seals clearances for up to 15% less energy consumption. Optional Variable Speed Drive (VSD) reduces additional 30%-35%.
  • High Quality Air. Totally oil-free, cool and contaminant free air.
  • Environmentally Friendly Design. No gear noise, no oil, low discharge temperature.
  • High Reliability. Low operating speed increases bearing life for reduced down time.
  • Low Maintenance Cost. Air end does not require rebuilds, Low Life Cycle Cost (LCC) with ZWV.
  • Quiet Enclosure.
