Description
Hankison FLEX 4.5 Refrigerated Compressed Air Dryer with Pre & Post Filtration – 450 SCFM
The Hankison FLEX 4.5 Refrigerated Compressed Air Dryer with Pre & Post Filtration delivers reliable, energy-efficient moisture removal for compressed air systems up to 450 SCFM. Designed with Hankison’s advanced phase change material (PCM) thermal storage technology, the FLEX 4.5 automatically matches power consumption to system demand, helping reduce operating costs while maintaining consistent pressure dew point performance.
Unlike traditional non-cycling refrigerated dryers that run continuously regardless of load conditions, the FLEX Series cycles intelligently based on airflow demand. This improves efficiency, reduces electrical consumption, and supports stable air quality across fluctuating production environments.
Each FLEX 4.5 dryer now ships standard with integrated pre- and post-filtration, providing built-in protection against oil aerosols, particulate contamination, and liquid moisture without requiring additional filtration packages. The result is cleaner compressed air, simplified installation, and enhanced protection for downstream equipment.
The FLEX 4.5 is ideal for manufacturing plants, CNC machining operations, woodworking facilities, automotive production environments, packaging lines, and multi-shift industrial compressed air systems requiring dependable refrigerated drying performance with integrated filtration protection.

Standard Pre & Post Filtration Included
Every FLEX 4.5 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 and automation equipment
- Improves reliability across compressed air distribution systems
- 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 dynamic manufacturing environments.
Air Quality Performance
The FLEX 4.5 delivers compressed air consistent with ISO 8573-1 Class 4–5 pressure dew point performance, making it suitable for most industrial compressed air applications requiring dependable moisture removal and equipment protection.
