ZH & ZH+
Oil-free air centrifugal compressor ZH and ZH+


Features
The Atlas Copco ZH and ZH+ are high-efficiency, oil-free centrifugal air compressors designed for heavy-duty industrial applications. While both share the same robust core engineering, the ZH+ is an all-inclusive packaged solution, whereas the standard ZH is a modular system that allows for separate component installation.
Core Shared Features (ZH & ZH+)
- Class 0 Clean Air: Certified ISO 8573-1 CLASS 0 (2010) oil-free air to protect sensitive production processes.
- No Instrument Air Required: Unique seal design eliminates the need for an external compressed air source to maintain oil-free certification.
- Advanced Impellers: In-house engineered impellers balance high flow rates with optimal energy efficiency.
- Inlet Guide Vanes: Energy-saving electric guide vanes accurately adjust intake air volume to manage shifting flow requirements.
- AGMA Class A4 Gears: High-precision, easily accessible gearbox configuration minimizes mechanical losses.
- Heavy-Duty Cooling: High-efficiency stainless steel intercoolers and after-coolers maximize thermal transfer while resisting corrosion.
- Elektronikon Controller: Advanced microprocessor system regulates pressure within tight parameters to optimize motor workload.

Benefits
The Atlas Copco ZH and ZH+ are advanced oil-free centrifugal air compressors designed to deliver 100% pure, certified compressed air for demanding industrial operations.
Core benefits of these compressors include:
- ISO 8573-1 CLASS 0 Certification: Guarantees absolute oil-free air, eliminating contamination risks in sensitive environments like the food and beverage or chemical industries.
- High Energy Efficiency: Utilizes custom-designed impellers and advanced turbo technology to provide high flow rates while keeping energy consumption low.
- Integrated Solutions: The ZH+ model arrives as a complete, plug-and-play package with an inlet silencer, integrated blow-off valve, and sound-attenuating canopy.
- Optimized Control: Features the Elektronikon control system for smart monitoring, which prevents costly blow-off events and reduces total operation costs.
- Supreme Reliability: Built with robust components that minimize pressure drops and friction losses, maximizing the equipment’s overall package efficiency.
