SRL Series Oil Free Scroll Air Compressors
The SRL Series provides oil free air reliably, efficiently and quietly! Built on Hitachi engineering, the SRL Series represents advanced scroll compressor technology to meet your oil free compressed air needs — today and tomorrow.
In many operations, compressed air comes into contact with items in the manufacturing process. When air purity is critical — oil free air is essential. Oil particulates in compressed air can contaminate downstream processes and production. Oil Free compressors help eliminate potential contamination as no oil or lubricant is introduced into the air compression process. Reduced risk of contamination helps improve your business operations and profitability.
SRL Series scroll air compressors are the perfect choice for applications requiring oil free air, including:
Food and beverage manufacturing
Research & Development applications
High quality oil-less instrument air

Class 0 Oil Free Air
For applications in which air purity is essential, including pharmaceuticals, food and beverages, electronics, automotive painting, and textiles. SRL Series compressors are certified oil free under ISO8573-1.
Scroll Compression Technology
Within each SRL Series pump are two scrolls —one orbiting; one fixed. Air entering the compression chamber is gradually reduced as the orbiting scroll rotates. Compressed air is exhausted through the outlet at the center. Because air movement is continuous from the suction port through the discharge port, scroll compressors provide pulsation free delivery of compressed air.
SRL Exclusive Scroll and Pump Design
Patented scroll wrap design with labyrinth seal provides superior performance and reliability
Proprietary tip seal reduces air leakage while extending service intervals
Two air inlets to reduce stress on pump (5.5 kW pump only)Leads to tighter upper air band
Extends life of pump
Normal maintenance can be completed without disassembling pump
Integrated Design for Maximum Benefits
Highly efficient coolingMulti stage cooling reduces ambient temperature out
Receiver tank helps dissipate heat while reducing compressor starts/stops
Air pressures to 145 psig
Extremely quietFull enclosure standard
Mechanical and electrical vibration isolation
Designed to be placed at point of air need
Sound levels as low as 48 dB(A)
Compact design reduces floor space needed
Maintenance friendlyEasy accessibility for inspection and maintenance
SRL Series compressors are not just quiet — they are super quiet. Noise levels as low as 48 dBA make Sullair SRL Series compressors suitable for indoor applications and do not require a separate sound attenuated room. In fact, these compressors may be installed at point-of-use which results in lower installation and piping costs.
