Atlas LE/LT Series

An Atlas Copco LE/LT compressor serves as a high-performance industrial air solution, engineered to deliver exceptional reliability and efficiency. The 10-bar LE model and the 15/20/30-bar LT series produce high-quality compressed air at the lowest operating temperatures in the industry, significantly reducing thermal stress on components. With minimal oil carryover, these compressors ensure cleaner air output, supporting sensitive downstream processes. Their robust construction, built on a proven design and premium-grade materials, guarantees stable performance, extended service life, and reduced total cost of ownership.

Products Description

Product Features

Automotive-Grade Cylinder Assembly
- Crafted from high-silicon aluminum alloy and finished with precision CNC machining, these cylinders minimize internal clearances and reduce friction to enhance operational efficiency and component longevity.

Unit performance is evaluated in accordance with ISO 1217, Edition 4, Annex C (2009). The average sound pressure level is determined at a 1-meter distance using the ISO 2151/Pneurop/Cagi PN8NTC2 testing standard, with a permissible tolerance of ±3 dB(A). The system offers selectable drying solutions—refrigerant, desiccant, or membrane dryers—each paired with appropriately matched filtration components to ensure consistent air quality and optimal performance across varying operating conditions.
