HN Series 100% Oil-Free Air Compressors
The Chicago Pneumatic HN Series 100% oil-free air compressors are engineered for continuous industrial applications where absolute air purity, high reliability, and consistent performance are critical. Designed with time-proven multi-stage oil-free piston compression technology, the HN Series delivers 100% oil-free compressed air for sensitive processes across air and nitrogen applications.
Built to operate 24/7 in demanding industrial environments, HN compressors combine robust mechanical design with advanced control and monitoring systems to ensure maximum uptime and long service life.
Key Features & Benefits
100% Oil-Free Compressed Air
The HN Series uses oil-free compression chambers with PTFE piston rings, ensuring zero oil contamination. This makes the compressors ideal for applications where air quality directly impacts product safety, regulatory compliance, and output quality.
Designed for Continuous Industrial Operation
- Engineered for 24/7 continuous operation
- 2-stage, 3-stage, and 4-stage compression configurations available
- High-grade stainless-steel valves for extended service life
Foundation-Free Horizontal BOP Design
The horizontal balanced opposed piston (BOP) design with dynamic balancing significantly reduces vibration. A specially engineered base frame with elastomer anti-vibration mounts eliminates the need for special foundations, simplifying installation and lowering setup costs.
Integrated Electrical & Control Systems
- Professionally integrated Star-Delta starter panel
- Optional VSD (Variable Speed Drive) for energy-efficient operation
- ES 4000 controller for total monitoring and supervision
Energy-Efficient & Sustainable
- Available with IE3 premium-efficiency motors
- Lower power consumption and reduced carbon footprint
- Optimized compressor management for reduced operating costs
Advanced Controller & Monitoring
The HN Series is equipped with the advanced ES 4000 controller, delivering intelligent supervision, protection, and energy optimization.
- Energy-saving compressor management
- Fault history for quick diagnostics
- Intelligent protection and alarm system
- Programmable start / stop timer
- Maintenance and warning indications
- Multilingual user interface
- Full integration with VSD systems
Additionally, ICONS connectivity enables remote monitoring and optimization of compressed air consumption, helping prevent failures and reduce energy waste.
Moisture Control & Air Quality
To ensure consistently high air quality, the HN Series incorporates effective moisture management systems:
- Integrated timer-based automatic drain
- Efficient moisture separation
- Reduced risk of water contamination in compressed air lines
This makes the HN Series ideal for critical industrial processes requiring clean, dry, oil-free compressed air.
