Description
Hankison FLEX 3.1 Refrigerated Compressed Air Dryer with Pre & Post Filtration – 300 SCFM
The Hankison FLEX 3.1 Refrigerated Compressed Air Dryer with Pre & Post Filtration delivers high-efficiency moisture removal and contaminant protection for compressed air systems up to 300 SCFM. Built around Hankison’s advanced phase change material (PCM) thermal storage technology, the FLEX 3.1 automatically matches power consumption to compressed air demand, reducing operating costs while maintaining stable pressure dew point performance across changing load conditions.
Unlike conventional non-cycling refrigerated dryers that operate continuously, the FLEX Series cycles intelligently based on system demand. This improves energy efficiency, extends component life, and delivers consistent compressed air quality in demanding industrial environments.
Each FLEX 3.1 dryer now ships standard with integrated pre- and post-filtration, providing immediate protection against oil aerosols, particulate contamination, and liquid moisture. The result is cleaner compressed air, simplified installation, and improved reliability for downstream equipment.
Ideal for larger compressor rooms, production facilities, CNC operations, woodworking plants, packaging systems, and multi-shift manufacturing environments, the FLEX 3.1 offers dependable drying performance with built-in filtration protection.

Standard Pre & Post Filtration Included
Every FLEX 3.1 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 life of pneumatic tools, automation components, and valves
- 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 traditional non-cycling dryers, this approach significantly reduces power usage during partial-load operation, helping lower long-term operating costs in fluctuating production environments.
Air Quality Performance
The FLEX 3.1 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 equipment protection.
