Breathing Air

Compressed Air Systems for Breathing Air

Sullair SRL Series scroll air compressors are the perfect choice for applications requiring oil free air, including:

– Pharmaceuticals
– Food and beverage manufacturing
– Electronics
– High-technology manufacturing
– Research & Development applications

– Robotics
– Dental applications
– Automotive
– Paint
– High quality oil less instrument air

Why Oil Free?
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 protability.

Air Quality Standards

ISO 8573-1 Classes

Class 0 Oil Free Air — For applications in which air purity is essential, including pharmaceuticals, food and beverages, electronics, automotive painting, and textiles. Under the ISO 8573-1 Class Zero classi cation, Sullair compressors are designed to operate oil free, minimizing the risk of contaminating the process air or gas.

THE SULLAIR SRL Series DIFFERENCE

The Sullair SRL Series provides oil free air reliably, ef ciently 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.
