Why the LS Series
Precision performance
Steel mills, tire plants, automotive, forging, chemical processing, paper and large manufacturing run on these. Three reasons why.
World-class efficiency
Less energy to power your compressors means more savings.
- Next generation air end. Designed to be the most efficient Sullair air end ever.
- Electronic Spiral Valve. Matches capacity to system demand with more precision. Optional.
- Variable Speed Drive. Adjusts motor speed to the air you actually need. Optional.
Easy to run, easy to service
Easier and more intuitive operating and servicing.
- 10 inch touch screen controller. Every key performance parameter in one place.
- AirLinx remote connectivity. Check the compressor from a computer, tablet or phone.
- Streamlined maintenance. Enclosed unit with easily removable hinged door panels.
Legendary durability
Expect more uptime, for a longer time.
- Simplified air end. The same bulletproof quality Sullair has produced for decades.
- TEFC motor, 1800 rpm. Protected from weather, dirt and moisture, and slow-running for longer life.
- Full base frame. Helps keep dirt and dust out of the unit.

Inside the machine
Features that perform. Benefits that count.
Next generation air end
- Updated casting with internally ported lubricant passages
- Asymmetrical rotors designed, engineered and manufactured in the USA
- Proven bearing design to extend bearing life
- LS160 to LS260 add an enhanced air end package with an improved inlet valve
OptimalAir air filter
- Heavy-duty inlet filter holds up to five times more contaminant than conventional cellulose filters
- Cleaner intake air keeps fluid clean and extends component life
- 99.9% efficiency per ISO 5011
Air-fluid separator
- Low pressure drop helps save energy
- Low carryover, under 2 ppm, means fewer lubricant top-offs

- ASME and CRN approved
Cooling system
- Heavy-duty, oversized cooling designed for 115°F (46°C) applications
- Easy-clean access panels built into the package

Sullair Touch Screen controller
The ultimate in user control
- 10 inch color screen for easy viewing and intuitive operation
- Menu-driven screens give quick access to compressor controls
- Integrated graphing and trending to analyze performance
- Sequences up to 16 compressors
AirLinx remote monitoring
Your compressor, in your pocket
- Connect from anywhere and reduce the risk of unplanned downtime
- Monitor pressure, temperature, running hours and service hours
- Alerts for service and warnings
- Data collected at 15 minute intervals over a cellular connection
- Reporting from basic to advanced

Capacity control
Three ways to match supply to demand
Energy can cost more than the machine within a few years. Pick the control scheme that fits how your plant actually uses air.
LS · Fixed speed
Steady base load
The standard package for plants with consistent demand, or as the base-load machine in a sequenced system.
- Wye-Delta starter
- Sequence up to 16 units from the touch screen
LS-S · Electronic Spiral Valve
Demand that moves
A variable displacement air end opens and closes internal bypass ports so less air is compressed when less is needed.
- Holds a tight 1 psi control band
- Up to 55% turndown, up to 60% on larger models
- Suits high elevation and dirty environments
LS-V · Variable Speed Drive
Demand that swings
Motor speed follows demand, so the compressor makes only the air you use.
- Soft start with unlimited starts and stops
- Stable system pressure, relief from peak demand charges
- Possible utility rebates
