The AC Infinity AXIAL S1225D dual-fan system has become a benchmark for enthusiasts tackling ventilation, thermal regulation, and airflow optimization projects. Combining industrial-grade durability with intuitive controls, this 120mm × 25mm solution excels in residential and professional settings. Below, we explore its design, performance metrics, installation versatility, and real-world applications.
At the heart of the AXIAL S1225D's reliability is its dual-ball bearing system, engineered for 67,000 hours (7.6 years) of continuous operation. Unlike sleeve-bearing competitors, this design:
- Supports 360° mounting flexibility (horizontal, vertical, or angled)
- Reduces wear from dust/debris ingress due to sealed chambers
- Maintains stable RPM even under fluctuating temperatures (32°F–140°F)
The inline rotary knob allows granular speed adjustments from 700–2,450 RPM, translating to:
Speed Tier | Airflow (CFM) | Noise (dBA) | Use Case |
---|---|---|---|
Low (700 RPM) | 20 | 16 | Bedrooms, media rooms |
Medium (1,500 RPM) | 45 | 28 | Server racks, grow tents |
High (2,450 RPM) | 69 | 38 | Fireplace heat redistribution |
Pro Tip: For noise-sensitive setups, operate at ≤1,800 RPM (≤30 dBA)—quieter than a library whisper.
Component | Material | Benefit |
---|---|---|
Housing | Aircraft-grade aluminum | Heat dissipation, corrosion resistance |
Blades | UL 94-compliant PBT thermoplastic | Flame retardancy, low warp at high RPM |
Guards | Powder-coated steel mesh | Finger protection without airflow restriction |
Mounting Brackets | Reinforced ABS + stainless hardware |
The included dual-axis swivel brackets enable:
- Wall/Ceiling Mounts: Secure to joists using 8 included screws/nuts
- Angled Airflow: Redirect heat from wood stoves to adjacent rooms (see Fig. 1)
- Inline Ducting: Connect to 4"–6" ducts via optional adapters (sold separately)
Case Study: A Reddit user achieved 14°F temperature reduction in a network cabinet using push-pull airflow.
1. Power Connection: Attach the 6ft cord to any 100–120V outlet (10W/fan).
2. Daisy-Chaining: Link both fans via the 4ft inter-fan cable.
3. Controller Placement: Mount the rotary dial within reach using adhesive pads.
Note: For smart home integration, pair with a Wi-Fi outlet (e.g., TP-Link Kasa) for remote scheduling.
At maximum RPM (2,450), each fan delivers:
- 69 CFM airflow
- 4.4 mm-H₂O static pressure
Ideal for overcoming resistance in:
- HVAC ducts
- Filtered grow tents
- Multi-layered server racks
Parameter | Range | Certification |
---|---|---|
Operating Humidity | 35–85% RH | RoHS, CE |
Storage Temperature | -40°F–158°F | UL E503903 |
Field Test: Users reported zero performance degradation in 80% RH greenhouse environments.
- Setup: Mount fans above fireplace mantle angled toward living spaces.
- Result: 25–40% faster room heating (per customer reviews).
- Configuration: Install 2–4 units (push-pull) in 42U racks.
- Benefit: Reduced reliance on AC units, cutting energy costs by ~18%.
Pro Tip: Add a thermostat controller (e.g., AC Infinity CLOUDLINE T6) for auto-speed adjustment.
- Air Exchange Rate: 69 CFM × 2 fans = 138 CFM total, sufficient for 4'×8' tents.
- Noise Mitigation: Run at 1,200 RPM (22 dBA) during dark cycles.
1. Monthly Maintenance: Use compressed air to remove dust from blades and guards.
2. Quarterly Cleaning: Wipe guards with isopropyl alcohol (70%) to prevent buildup.
3. Annual Check-Up: Lubricate bearings with synthetic oil (non-conductive).
Regular maintenance ensures optimal performance and longevity of the AXIAL S1225D fans.
Symptom | Likely Cause | Solution |
---|---|---|
Humming noise | Loose bracket | Tighten all screws/nuts |
Reduced airflow | Clogged filter/guard | Clean with soft brush |
Intermittent power | Faulty rotary knob | Contact AC Infinity support |
These troubleshooting tips can help users resolve common issues quickly.
The AXIAL S1225D redefines versatility in compact cooling solutions, merging laboratory-grade engineering with plug-and-play usability. Whether redistributing fireplace heat, stabilizing server environments, or optimizing grow tent climates, its impressive lifespan and UL/CE certifications make it a future-proof investment.
With its robust features and practical applications across various environments, the AXIAL S1225D is not just a fan; it's an essential tool for anyone serious about thermal management.
Yes—each fan operates independently. Replacement units (HS1225A) retail for $19.99.
No. Keep the dial away from moisture sources.
While smaller, dual 120mm fans provide 22% higher static pressure, making them ideal for restricted spaces compared to single larger fans.
Yes—standard 120mm screw spacing supports most aftermarket guards.
