Description
Hankison FLEX 2.1-4 Refrigerated Compressed Air Dryer with Pre & Post Filtration – 200 SCFM
The Hankison FLEX 2.1‑4 Refrigerated Compressed Air Dryer with Pre & Post Filtration delivers dependable moisture removal and integrated contaminant protection for compressed air systems up to 200 SCFM. Designed with Hankison’s advanced phase change material (PCM) thermal storage technology, the FLEX 2.1-4 automatically matches energy consumption to compressed air demand, helping reduce operating costs while maintaining stable pressure dew point performance across fluctuating plant conditions.
Unlike traditional non-cycling refrigerated dryers that operate continuously regardless of load, the FLEX Series cycles intelligently based on airflow demand. This reduces electrical consumption and improves long-term system efficiency while protecting downstream equipment from moisture-related damage. FLEX dryers eliminate liquid contamination from compressed air while delivering cost-effective energy savings proportional to system demand.
Each FLEX 2.1-4 dryer now ships standard with integrated pre- and post-filtration, providing immediate protection against oil aerosols, particulate contamination, and liquid moisture without requiring additional filtration packages at installation.
The FLEX 2.1-4 is ideal for medium-to-large compressor rooms supporting CNC machining, manufacturing lines, woodworking facilities, packaging equipment, automotive production, and multi-shift industrial air systems requiring reliable refrigerated drying with built-in filtration protection.

Standard Pre & Post Filtration Included
Every FLEX 2.1-4 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 life of pneumatic tools, valves, and automation components
- Improves reliability across compressed air distribution systems
- Eliminates the need to size and purchase separate inline filters
This integrated filtration package 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. Instead of running continuously like conventional non-cycling dryers, the FLEX 2.1-4 cycles as needed, significantly reducing energy usage during partial-load operation and lowering lifecycle operating costs.
Air Quality Performance
The FLEX 2.1-4 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.
