Jalis –
Excellent compressor!
We installed the ZH 355 in our pharmaceutical facility. The centrifugal design delivers massive airflow with minimal vibration and noise. After 14 months of 24/7 operation, zero unplanned downtime. This compressor is a long-term investment that pays for itself.
Chen Wei –
Genuine Atlas Copco quality through and through.
The ZH 710+ transformed our petrochemical production. Constant pressure at 10 BAR, even with fluctuating demand. The integrated control system optimizes every cycle, and maintenance intervals are impressively long. Genuine Atlas Copco quality through and through.
Hans V –
Atlas Copco's reliability is unmatched.
Upgraded to the ZH⁺ 700 for our automotive plant. The oil-free Class 0 air eliminated all contamination risks, and the energy efficiency cut our power costs by 18%. Performance is rock-solid at full load. Atlas Copco’s reliability is unmatched.
