Frameless Fan 9025: Product Overview

The Frameless Fan 9025 measures 90mm × 90mm × 25mm and is engineered to provide high airflow with minimal vibration and noise. Equipped with a pure copper coil motor, it delivers stable operation and excellent energy efficiency. This fan’s frameless design eliminates the bulky outer frame, allowing for a slimmer profile and easier integration into specialized equipment where space and weight are critical considerations.

Key specifications include:

Bearing Type: Sleeve bearing for smooth, quiet operation.

Rated Voltage: 12V DC (operational range 10.8V to 13.2V).

Current: Approximately 0.25A.

Speed: Around 2100 RPM.

Noise Level: Approximately 30 dBA, suitable for noise-sensitive environments.

Weight: About 75 grams.

Durability: Features an all-copper enamelled wire coil motor with a lifespan up to 40,000 hours under continuous operation.

Six major upgrades enhance this model’s performance: improved energy efficiency, stronger wind power, noise reduction, durable pure copper motor, easy installation with a sturdy mounting bracket, and overall long-lasting durability.

Assembly Techniques and Tips for Frameless Fans

Assembling frameless fans like the 9025 requires careful attention to ensure optimal performance and longevity:

Direct Mounting: Frameless fans are designed to be mounted directly onto circuit boards or inside enclosures without the need for bulky frames. Use precision mounting brackets or custom fixtures to secure the fan firmly while avoiding stress on the impeller.

Vibration Isolation: To minimize vibration transmission, use rubber grommets or silicone pads between the fan and mounting surfaces. This reduces noise and mechanical wear.

Electrical Connections: Ensure proper soldering or connector use for lead wires, maintaining correct polarity and secure contacts to prevent electrical faults.

Clearance and Airflow: Maintain sufficient clearance around the fan blades to avoid obstruction and optimize airflow. Avoid placing cables or components too close to the impeller.

Regular Maintenance: Periodically inspect for dust accumulation and clean the fan blades and motor area to sustain cooling efficiency and reduce noise.

Following these assembly tips ensures that the Frameless Fan 9025 operates quietly, efficiently, and reliably over its service life.

Application of Frameless Fan 9025 in Special Equipment

The Frameless Fan 9025 is widely used in various types of special equipment, where compact size, reliable cooling, and low noise are essential. Typical applications include:

Industrial Control Systems: Cooling sensitive electronic components in control cabinets and automation equipment.

Military and Defense Devices: Providing efficient thermal management in rugged, space-constrained environments.

Medical Equipment: Ensuring stable temperatures in diagnostic machines, imaging devices, and portable health monitors.

Power Supplies and UPS Systems: Maintaining optimal operating temperatures to enhance reliability and lifespan.

Welding Machines and Instrumentation: Cooling power electronics and sensors subject to high thermal loads.

Its frameless design allows seamless integration into these specialized devices, where traditional fans may be too bulky or noisy. The fan’s durability and energy efficiency support continuous operation in demanding industrial and commercial settings.
