Our patent-pending new air end continues to featureasymmetrical rotors precision milled for ultimate performance. Andnow the Sullair air end includes:n  Simpler design for increased uptime. Sullair engineers havedeveloped the latest generation of air ends with the optimalnumber of parts using new casting technologiesn  Larger rotor profile (230mm) for increased efficiencyThe result? The highest performing Sullair air end. Ever. All withoutsacrificing the durability Sullair is known for.5

Features that perform.Benefits that count.A Sullair compressor is much greater than the sum of its parts. The new LS 90 -110 featuresa patent-pending package design, in which all components are specially designed,engineered and manufactured to perform at the highest levels.413526

CapacityControl OptionsElectronic Spiral ValveThe costs to operate an air compressor — especially energycosts — can quickly exceed the initial purchase price. Effectivelymatching compressor production capacity to your facility needs isthe best way to save both energy and money.Sullair offers two capacity control options to mosteffectively manage your compressed air production:n NEW! Electronic Spiral Valven Variable Speed Drive8

NEW! Sullair Electronic Spiral Valve ControlsFor the first time, electronic spiral valve controls are available with Sullair compressors. This new feature combinesthe performance and reliability Sullair is known for in spiral valve technology with the ease and precision of touchscreen controls.Spiral valve technology represents an energy-efficient control scheme that matches compressor displacement todemand without reducing inlet pressure or increasing compression ratios. Managed by the Sullair Touch Screen Controller,the electronic spiral valve maintains a tight 1 PSI control band — closely matching machine supply to demand need.Variable Displacement Air EndCompressors with electronic spiral valve feature a variable displacement air end.Compression volume is varied to suit air demand by progressively opening or closinginternal bypass ports on the air end.n  Closed bypass ports utilize the entire length of the rotor and compression chambern  Partially open and open bypass ports reduce the length of the rotor used for aircompression, which in turn utilizes less energyBYPASS PORTS IN STATORSpiral Valve Benefitsn  Capacity is matched to system demand, reducing cycling time and extending component lifen  Multiple Spiral Valve compressors may be sequenced to operate in synchronous fashionn  Up to 55% turndown capability with Electronic Spiral Valven  Outstanding energy efficiency in all operating conditions including:n  High elevationn  Dirty environmentsRotors removed to show Bypass PortsCLOSED BYPASS PORTSPARTIALLY OPEN BYPASS PORTSOPEN BYPASS PORTSWhen the bypass ports are closed, the fullcompression chamber is used.With the bypass ports partially open — the compression chamber isshortened. Less intake air is fully compressed — saving energy.Fully open bypass ports further shorten the compression chamberproviding maximum turndown.The Sullair LS Series is the first to offer Electronic Spiral Valve operation with Sullair compressors. Electronic Spiral Valves offer more precision when compared to manually operated spiral valves.9
