We manufacture and supply six main categories of cooling fan products for industrial, commercial, and residential applications:
For comprehensive technical guidance on all product categories, consult our Cooling Fan Selection Guide.
AC cooling fans operate directly from alternating current power sources (typically 100V-240V). They provide constant-speed operation and are commonly used in electrical cabinets and industrial equipment where wiring simplicity is valued. AC fan speed is tied to line frequency (50Hz or 60Hz), making them predictable in stable power grid environments.
DC cooling fans run on low-voltage DC power (5V, 12V, 24V, 48V) and allow flexible speed control through voltage adjustment or PWM signals. DC fans are suitable for electronics, power supplies, and battery-powered systems where variable speed is needed. PWM control enables precise speed regulation across wide ranges.
EC cooling fans use electronically commutated motors with integrated control electronics that can accept both AC and DC input power. EC fans offer the highest energy efficiency and advanced features like constant airflow control, temperature-based speed regulation, and communication interfaces for system integration.
For detailed comparisons and selection guidance, see our Cooling Fan Selection Guide.
USB cooling fans are portable cooling solutions operating from standard USB power sources, typically providing 5V DC power through USB-A, USB-C, or micro-USB connectors. USB 2.0 specifications deliver up to 500mA at 5V (2.5W), while USB 3.0 and USB-C Power Delivery can supply higher currents for more powerful configurations.
USB fans often incorporate integrated speed control modules with multiple operating modes (off, low, high speed). Low-speed mode reduces power consumption and acoustic output, while high-speed mode provides maximum cooling capacity for peak load conditions.
For detailed information about USB fan power requirements, speed control features, and portable applications, see our USB Cooling Fan Guide.
Window frame ventilation fans are non-invasive multi-fan ventilation systems designed for installation in existing window frames without structural modifications. They address indoor air quality challenges in residential and commercial spaces where traditional ventilation solutions are impractical.
These systems feature adjustable mounting mechanisms, stepless speed control, and weather-resistant design. Multi-fan configurations distribute airflow across window opening width, providing uniform air exchange. Applications include kitchens, bathrooms, bedrooms, and living areas requiring targeted ventilation without extensive building modifications.
For installation information, acoustic considerations, and energy efficiency guidelines, see our Window Ventilation Fan Guide.
Stove blower fans (combustion assist fans) are high-performance blowers designed to enhance combustion efficiency in wood stoves, gasification stoves, and outdoor cooking equipment. They operate by forcing air into combustion chambers, increasing oxygen supply to fuel, which improves burn efficiency and reduces smoke production.
High-performance stove blower fans employ dual-fan or dual-bearing brushless motor configurations to achieve high airflow rates. They feature stepless speed control for precise airflow adjustment and dual-voltage power support (5V USB and 12V DC) for portable applications.
For performance characteristics, power source requirements, and combustion application considerations, see our Stove Blower Fan Guide.
