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.

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
