The LF-2X80 centrifugal compressor is for flows up to 6000 ACFM (10,200 AM3/hr) with maximum working pressures to 1440 psi (100 Bara).

The Sundyne LF-2X80 integrally geared multi-stage centrifugal process compressor utilizes our LF-2000 technology and experience to extend the LMC/BMC product line enabling greater flow, head, and horsepower capability.

-Flows to 6000 ACFM (10,200 AM³/hr)
-Max working pressure to 1440 psi (100 Bara)

The Sundyne LF-2X80 integrally geared multi-stage centrifugal compressor leverages our acclaimed LF-2000 technology and decades of expertise to extend the operational range of the LMC / BMC product line, enabling greater flow, head and horsepower capability. Immensely flexible, the LF-2X80 is available in both one- and two-stage configurations and can be easily packaged onto a skid to allow for optimized footprint and ease of installation. Additionally, the LF-2X80 can run continuously for 5 years -- due to its compliance with strict API 617 / 614 standards -- delivering oil-free process gas with no emissions day in and day out. With the full backing of our global network of Sundyne Authorized Service Centers, the LF-2X80 is available to order now as a full gas compression solution for use in refining, petrochemical, LNG, power and mining applications.

Integrally Geared Centrifugal, Multi Stage Compressors
Sundyne Corporation multi-stage centrifugal compressors deliver the same performance range as traditional piston-driven design, but they generate several operational efficiencies that set them apart as a superior alternative.

Sundyne Standard
In the 1960s, Sundyne (then Sundstrand Fluid Handling) emerged as the leading expert for integrally geared centrifugal compressors.
