ULTIMA 2 Stage Oil-Free Screw Air Compressor

Ultima U75-160 kW (100-215 HP)

This next gen oil-free air compressor utilizes high efficiency low/high pressure dry screw airends. Each airend is individually driven by a motor that operates at 97% efficiency. The Ultima provides up to 70% turndown, delivers low off-load power consumption, while maintaining a 63-69 dBA noise performance. This oil-free air compressor also provides superior heat recovery.

MPN: U75-160

Product Description

Ultima: A Revolution in Dry Screw Compressor Technology

What makes the Ultima so unique?

  • Most efficient two-stage dry screw compressor on the market
  • Uses independent low and high pressure dry screw airends
  • Each airend is individually driven by a variable-speed, permanent-magnet, water-cooled motor
  • Each motor operates at 97% efficiency (greater than IE4)
  • Large turn down range up to 70%
  • Lowest unloaded power consumption – only 8 kW
  • Significantly smaller footprint while maintaining 63-70 dBA noise performance
  • Water-cooled or air-cooled, both with heat recovery options

Superior Heat Recovery

  • All the major components in the Ultima are water-cooled providing more efficient performance
  • Approximately 94% of the energy used in a compressor is converted into heat. The closed loop cooling system in the Ultima cools all of the major components, removing heat from the motors, inverters and airends
  • Ultima cooling philosophy maximizes energy recovery from the complete compressor package
  • Ultima recovers 98% of the heated generated (approximately 12% more than standard), which can be used for other processes, reducing the building HVAC load
  • Outlet water temperatures up to 194F
  • Heat recovery connections are standard on water-cooled machines, optional on air-cooled machines


  • 100% Oil-Free 

Eliminates the risk of contamination

  • 13% Higher Efficiency

The Digital Gearbox drives each airend individually, significantly improving performance over the complete turndown range

  • Lowest Unloaded Power

Ultima uses only 8 kW when running unloaded as compared to >20 kW to conventional machines

  • >97% motor efficiency

Permanent magnet synchronous motors provide >97% efficiency and compact size

  • Up to 70% Turndown

Allows for a greater variation in demand without starting an additional compressor, saves energy

  • Ultra Quiet: 63 dBA

Fully enclosed water-cooled package offers industry leading noise performance as low as 63 dBA

  • 47% Smaller Footprint

Allows 3 machines to fit in the same space as 2 competitive machines

  • 98% Heat Recovery 

Excess heat is recovered for use in other plant processes

  • Easy Installation

No ducting required
