Hankison FLEX 5.5 Refrigerated Compressed Air Dryer with Pre & Post Filtration – 550 SCFM
The Hankison FLEX 5.5 Refrigerated Compressed Air Dryer with Pre & Post Filtration delivers high-capacity, energy-efficient moisture removal for compressed air systems up to 550 SCFM. Designed with Hankison’s advanced phase change material (PCM) thermal storage technology, the FLEX 5.5 automatically adjusts energy consumption to match compressed air demand, helping reduce operating costs while maintaining consistent pressure dew point performance.
Unlike traditional non-cycling refrigerated dryers that operate continuously regardless of load, the FLEX Series cycles intelligently in response to system demand. This improves efficiency, lowers electrical consumption, and supports stable compressed air quality across variable production conditions.
Each FLEX 5.5 dryer now ships standard with integrated pre- and post-filtration, providing built-in protection against oil aerosols, liquid moisture, and particulate contamination without requiring additional filtration packages. The result is cleaner compressed air, simplified installation, and improved reliability for downstream equipment and production processes.
The FLEX 5.5 is an excellent choice for manufacturing facilities, CNC operations, woodworking plants, automotive production environments, packaging systems, and multi-shift industrial compressed air applications requiring dependable refrigerated drying with integrated filtration protection.

Standard Pre & Post Filtration Included
Every FLEX 5.5 dryer includes integrated filtration designed to improve compressed air quality and protect downstream equipment:
- Removes upstream solids and oil aerosols before entering the dryer
- High-efficiency downstream polishing filtration
- Extends service life of pneumatic tools, automation components, and valves
- Improves compressed air system reliability across the facility
- Eliminates the need for separate inline filtration packages
This integrated configuration simplifies installation while improving total system protection.
Energy-Saving Load Matching Performance
The FLEX Series uses PCM thermal storage to align electrical consumption directly with compressed air demand. Compared to conventional non-cycling dryers, this significantly reduces energy usage during partial-load operation, lowering lifecycle operating costs in fluctuating production environments.
Air Quality Performance
The FLEX 5.5 delivers compressed air consistent with ISO 8573-1 Class 4–5 pressure dew point performance, making it suitable for most industrial compressed air systems requiring dependable moisture removal and equipment protection.
