Screw Blowers Screw Blower
Delta Hybrid

Delta Hybrid is the perfect synthesis of positive displacement blower and screw compressor. Unlike the conventional positive displacement blower (max. 1,000 mbar), the innovative screw blower uses a new and unique 3+4 compressor profile, which is specially designed for low pressure applications up to 1,500 mbar.
Delta Hybrid thus closes the gap in the previous machine mix and offers a wide range of services for precise design to meet the most diverse process requirements. The result is a new level of cost efficiency for compressed air applications.

The Delta Hybrid screw blowers

The Delta Hybrid Screw Compressor derives from the fusion between the screw compressor technologies and the rotary lobe blowers. This combination results in a machine that combines the technical advantages of the two concepts, offering new possibilities for generating positive pressure.

Roughly 90% of a compressor’s life cycle costs are consumed by energy. While this presents a huge challenge, AERZEN’s Delta Hybrid is providing companies with ideal solutions that enable large energy savings thanks to its compressor’s energy efficiency, even in high-pressure ranges.

Get the Delta Hybrid screw blower and enjoy benefits such as: 

  • Reduced life-cycle costs
  • Extraordinary energy efficiency
  • High reliability levels
  • Reduced maintenance needs
  • Increased range of pressures and applications
  • 100% pure process air, free of absorption materials and oil

There is no more comfortable way to generate pressure.

Significative energy savings, easy installation and commissioning, minimum maintenance: these characteristics are also directly reflected into the cost balance. A good reason for AERZEN to keep a special eye on them during the development of the Delta Hybrid Generation. The results convince even the smartest customers.

Extraordinary energy efficiency

  • Energy savings up to 30% compared to lobe blowers
  • Extended turndown ratio up to 1:5
  • Optimized air flow within the acoustic hood
  • Belt drive to match exactly the process requirements

Extremely compact design

  • Space-saving side-by-side installation
  • Smaller dimensioning of machine rooms
  • Easy access for service and maintenance work
  • Integrated power suppy panel having the same footprint

Reliability and durability

  • Patented bearing, theoretical lifetime of more than 70,000 hours (at 1.000 mbar pressure difference)
  • Patented driving- and conveying chamber sealings
  • 100% oil-free per Class 0 (certified per ISO 8573-1)
  • Patented silencer w/o absorption material
