80mm DC Axial Fan Series: Standard Cooling for Industrial & Commercial Devices
Designed for standard installation and medium-to-high power applications, SZR's 80mm DC axial fan series provides reliable, powerful cooling in an 80×80mm footprint. Available in thicknesses from 10mm to 38mm, these fans combine classic standard size with excellent airflow and static pressure, becoming the mainstream choice for industrial and commercial cooling. Built with UL94V-0 plastic components and supporting both sleeve and ball bearing configurations, the series operates on 12V, 24V or 48V DC inputs for versatile industrial power systems.
Design & Engineering Notes
The 80mm lineup caters to diverse cooling needs through varying thickness profiles:
- Slim models (8010, 8015): 10–15mm thickness for slim chassis, embedded equipment and space-limited installation scenarios.
- Mid-range thicknesses (8020, 8025): Balanced airflow, noise and power consumption, widely used in inverters, chargers and conventional industrial machines.
- Thicker variants (8030, 8038): Superior static pressure and air volume, ideal for sealed cabinets and high-heat-generating equipment.
All models feature color-coded wiring (red positive, black negative) for easy installation and comply with CE/RoHS standards.

Core Strengths
- Industry Standard Size: 80×80mm is the most universal mounting size, compatible with most industrial chassis and equipment reserved holes.
- High Air Volume & Static Pressure: Optimized blade design delivers strong heat dissipation for high-power heat-generating devices.
- Flexible Bearing Options: Sleeve bearings for cost-saving civilian use; ball bearings for high-temperature and long-time industrial continuous operation.
- High Temperature Resistance: Premium raw materials ensure stable operation in harsh working environments.
- Multi-Voltage Support: 12V/24V/48V options cover civilian, commercial and industrial power demands.
Ideal Applications
• Inverters and power inverter equipment
• Industrial chassis and control cabinets
• Battery chargers and power units
• Medical equipment and laboratory instruments
• Automation machinery and transmission devices
• Commercial ventilation and heat dissipation systems
Quick Support Q&A
Q: How do I choose between different thicknesses?
A: Slimmer models (≤15mm) work best for low-static-pressure open systems; thicker variants (≥20mm) provide higher static pressure for enclosed/filtered setups.
Q: Are low-noise versions available?
A: Yes. Custom blade profiles and speed tuning reduce noise output for noise-sensitive environments like medical and office equipment.
Q: What's the typical lifespan?
A: Sleeve bearing models offer 20,000–30,000 hours of continuous use; ball bearing versions extend this to 40,000–50,000 hours.
