Product Advantage
Hybrid Design for High Performance: The mixed flow structure (semi-curved blades + axial-centrifugal airflow path) achieves a static pressure of 400-600 Pa and airflow efficiency ≥85%—20% higher static pressure than axial blades and 15% larger airflow than centrifugal blades. It’s perfect for data centers needing both strong airflow and pressure to cool server racks.
Heat & Corrosion Resistance: The 25% glass fiber-reinforced PA6 material has a heat distortion temperature of ≥120℃ and withstands 800 hours of salt spray testing without corrosion. It maintains performance in high-temperature environments (e.g., 90℃ server rooms) and resists damage from humid HVAC condensate.
Low Vibration & Long Lifespan: The blade’s dynamic balance grade (G2.5) and precision-machined hub reduce vibration to ≤0.15mm/s at 2200 RPM, minimizing wear on the motor bearing—extending the fan’s overall service life by 4-6 years compared to standard blades.
Easy Integration & Customization: Features a 20mm inner bore with a spline connection, compatible with most 1.1-2.2kW AC motors. It supports length customization (blade outer diameter 380-450mm) and surface treatments (anti-static coating for data centers), adapting to diverse project needs.
Energy Efficiency & Cost Savings: When paired with a 1.5kW motor, it reduces energy consumption by 22% compared to traditional centrifugal blades. For a 10,000㎡ data center, this translates to annual electricity savings of $3,000-$5,000, aligning with sustainability goals.

Product Uses
1. Data Center Cooling Systems: Installed in precision air conditioners (PAC) for server racks. It delivers high static pressure to push airflow through dense server components, maintaining server temperatures below 35℃ and preventing overheating-induced downtime.
2. Commercial HVAC Air Handling Units (AHUs): Integrated into AHU systems for shopping malls and office buildings. The mixed flow design ensures uniform airflow distribution across large spaces (e.g., 5,000㎡ malls), reducing temperature differences between floors by 3-4℃.
3. Large Residential Complex Ventilation: Used in centralized exhaust systems for high-rise apartments. It provides sufficient airflow to ventilate 20-30 units simultaneously, removing cooking odors and moisture while reducing energy use compared to individual fans.
4. Industrial Process Cooling: Applied to cooling fans for plastic extrusion machines and metal processing equipment. The blade’s heat resistance (up to 90℃) and high airflow efficiency cool machine components, improving production efficiency by 10%-12% and reducing equipment maintenance frequency.
Product Operate Guide
Pre-Installation Preparation: Confirm the blade’s bore size and motor compatibility. Clean the motor spline shaft with a wire brush to remove rust, then apply high-temperature grease (resistant to 150℃) to ensure smooth assembly.
Installation Steps: Align the blade’s spline hole with the motor shaft, then push the blade onto the shaft until it locks into place. Tighten the 2×M8 flange bolts on the hub to a torque of 8-10N·m, ensuring the blade is perpendicular to the shaft.
Post-Installation Inspection: Use a laser alignment tool to check blade perpendicularity (tolerance ≤0.5°). Run the fan at rated speed for 15 minutes; if vibration exceeds 0.2mm/s, recheck the bolt tightness and spline alignment.
Maintenance Tips: Inspect the blade every 3 months for dust buildup—clean with a high-pressure air gun (pressure ≤0.8MPa). For data center use, replace the blade every 5 years to maintain airflow efficiency;
FAQ
1. Q: Can this blade be used in explosion-proof environments (e.g., chemical data centers)?
A: Yes, we offer an explosion-proof version with anti-static coating and non-sparking materials. It meets ATEX Zone 2 standards, suitable for environments with flammable gas concentrations <10% LEL.
2. Q: What’s the lead time for blades with custom outer diameters (e.g., 420mm)?
A: Standard 380mm blades have a 5-7 working day lead time. Custom diameters require 12-15 working days, including mold modification and aerodynamic performance testing to ensure airflow meets requirements.
3. Q: How to address reduced airflow over time?
A: First, clean dust from blades and fan grilles. If airflow remains low, check for blade wear (e.g., edge damage)—replace worn blades, as damaged edges reduce airflow efficiency by 15%-20%.
4. Q: What’s the warranty coverage for this blade?
A: We provide a 3-year warranty for material defects (e.g., heat-induced deformation, cracking). The warranty includes free replacement for qualifying issues and technical support for installation troubleshooting.
5. Q: Does the blade require a specific fan housing design?
A: It works with standard mixed flow fan housings (inner diameter 400-460mm). For optimal performance, use housings with a diffuser angle of 15°-20°—we can provide housing design specifications upon request.
