The Atlas Copco LZ – Zero-compromise performance in oil-free piston compression
Piston compressors have long been valued for their durability, low maintenance, and energy efficiency. Yet, they often came with drawbacks like high noise and limited control flexibility. The LZ series redefines expectations by eliminating these trade-offs. As one of the most comprehensive oil-free piston compressor ranges available, the LZ not only meets but exceeds demanding air quality and operational requirements.
Engineered for versatility, the LZ compressors offer a complete lineup with:
• Power options: 7–10 hp
• Pressure levels: 4–10 bar
• Voltage configurations: 230 / 400 / 460V
