Description
Hankison FLEX 8.1 Refrigerated Compressed Air Dryer with Pre & Post Filtration – 800 SCFM
The Hankison FLEX 8.1 Refrigerated Compressed Air Dryer with Pre & Post Filtration delivers high-capacity moisture removal and built-in contaminant protection for compressed air systems up to 800 SCFM. Designed with Hankison’s advanced phase change material (PCM) thermal storage technology, the FLEX 8.1 automatically adjusts energy consumption to match compressed air demand, helping reduce operating costs while maintaining stable pressure dew point performance. FLEX dryers are specifically engineered to eliminate liquid contamination while aligning electrical power usage with airflow requirements.
Unlike conventional non-cycling dryers that operate continuously regardless of load conditions, the FLEX Series cycles intelligently based on real-time system demand. This reduces energy usage, improves reliability, and extends service life across multi-shift production environments. The PCM thermal reservoir absorbs heat from incoming compressed air without large temperature swings, improving stability and efficiency.
Each FLEX 8.1 dryer now ships standard with integrated pre- and post-filtration, providing protection against oil aerosols, particulate contamination, and liquid moisture right out of the box.
The FLEX 8.1 is ideal for large compressor rooms supporting CNC machining centers, woodworking plants, packaging lines, automotive production environments, food processing support air systems, and general manufacturing facilities requiring dependable refrigerated drying performance at higher airflow capacities.

Standard Pre & Post Filtration Included
Every FLEX 8.1 dryer includes integrated filtration 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, valves, and automation components
- Improves reliability across plant air systems
- Eliminates the need for separate inline filtration packages
This integrated filtration 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 power usage during partial-load operation and supports lower lifecycle operating costs in facilities with fluctuating airflow demand.
Air Quality Performance
The FLEX 8.1 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 reliable moisture removal and downstream equipment protection.
