Key Features and Benefits
The AXEON HF5 Series is engineered with the industry’s leading polyamide thin-film composite technology. Unlike standard commercial membranes that require operating pressures of 150 to 225 psi, the HF5 Series achieves comparable salt rejection and flow rates at significantly lower pressures.
- Ultra-Low Energy Consumption: Operates at a nominal pressure of 80 psi (5.52 bar), reducing pump energy requirements and operational costs.
- Cold Water Performance: Specifically aimed at countering the negative effects of cold water temperatures, which typically reduce RO production rates.
- High Flow Rates: Delivers permeate flow ranging from 225 GPD for smaller 2.5-inch elements up to 2,500 GPD for 4-inch commercial elements.
- High Rejection: Maintains a nominal salt rejection rate of 98.50%, ensuring high-quality product water.
- Vacuum Integrity Tested: Every element is 100% vacuum integrity tested to ensure reliability out of the box.
Technical Specifications
The HF5 Series is available in standard commercial sizes, including 2514, 2521, 2540, 4014, 4021, and 4040 configurations. These elements fit nominal 2.5-inch and 4.0-inch I.D. membrane housings.
| Part Number | Model Description | Applied Pressure (psi / bar) | Permeate Flow (GPD) | Nominal Salt Rejection (%) |
|---|---|---|---|---|
| 208125 | HF5 – 2514 | 80 / 5.52 | 225 | 98.50% |
| 208083 | HF5 – 2521 | 80 / 5.52 | 400 | 98.50% |
| 208084 | HF5 – 2540 | 80 / 5.52 | 850 | 98.50% |
| 200392 | HF5 – 4014 | 80 / 5.52 | 600 | 98.50% |
| 200393 | HF5 – 4021 | 80 / 5.52 | 1,000 | 98.50% |
| 200394 | HF5 – 4040 | 80 / 5.52 | 2,500 | 98.50% |
Note: Permeate flow rates and salt rejection based on the following test conditions: 550 ppm filtered and dechlorinated municipal tap water, 77°F (25°C), 15% recovery, and 80 psi applied pressure.
Detailed Operating Limits
To ensure the longevity of the membranes and maintain warranty status, it is critical to adhere to the manufacturer’s operating limits. The HF5 Series is robust, but like all polyamide membranes, it is sensitive to oxidizers like chlorine.
| Membrane Type | Polyamide Thin-Film Composite |
| Max. Operating Temperature | 113°F (45°C) |
| Max. Operating Pressure | 400 psi (27.58 bar) |
| pH Range (Continuous) | 2 – 11 |
| pH Range (Cleaning) | 1 – 13 (30 min term) |
| Max. Feed Silt Density Index (SDI) | 5 |
| Chlorine Tolerance | 0 ppm |
Who Should Use AXEON HF5 Series?
The AXEON HF5 Series is ideally suited for a variety of commercial and industrial applications where energy efficiency and reliable tap water purification are paramount. They are particularly beneficial for:
- Commercial Drinking Water Systems: Ideal for restaurants, offices, and kiosks requiring high-quality water at low line pressures.
- Cold Climate Applications: Excellent for regions with lower feed water temperatures where standard membranes struggle to produce adequate flow without heating or boosting pressure.
- Light Industrial Applications: Perfect for spot-free rinse systems, small bottling lines, and manufacturing processes using municipal feed water.
- Energy-Conscious Facilities: Facilities looking to reduce the electrical load of their high-pressure pumps.
