SZR Bracket-Style Axial Cooling Fan Series
SZR's 30mm–120mm Support Fan Series is a line of frame-less, bracket-mounted axial cooling fans engineered for compact, space-constrained thermal management applications. Eliminating the need for a full outer frame, these fans integrate directly into device enclosures via built-in mounting brackets, reducing footprint while delivering reliable airflow.
Available with sleeve or ball bearing options, multi-voltage DC configurations (5V / 12V / 24V), and 7 standard sizes (30×10mm to 120×25mm), the series balances cost efficiency, performance, and durability for consumer and industrial electronics. All models comply with CE and RoHS standards to meet global regulatory requirements.
Key Features

Details |
|
Bracket-Only Design |
Frame-less direct-mount structure reduces installation footprint by ~30% vs. standard framed fans, ideal for slim-profile devices. |
|
Full Size Range |
7 standard dimensions to match airflow and space constraints: 30×10, 40×10, 50×10, 60×10, 80×25, 90×25, 120×25 (mm). |
|
Dual Bearing Options |
- Sleeve bearings: Cost-effective for low-duty, low-vibration applications. - Ball bearings: Extended lifespan (up to 50,000 hours MTBF @ 25°C) for high-duty cycles. |
|
Wide Voltage Tolerance |
Rated for 5V, 12V, and 24V DC with ±10% operating voltage range, ensuring stable performance across power supply variations. |
|
Low-Noise Operation |
Aerodynamically optimized impeller blades minimize turbulence, delivering quiet cooling (26.3–32.3 dBA) for noise-sensitive environments. |
|
Regulatory Compliance |
CE and RoHS certified, with rigorous testing for vibration, temperature cycling, and long-term reliability. |
