Key Features and Advantages:

Key Features:

1. Compact Size: The 30x30x10mm dimensions make it ideal for space-constrained applications, such as small electronic devices and portable equipment.
2. Multiple Bearing Options: Offers three bearing choices: ball, sleeve, and hydraulic. Users can select based on their application’s specific needs regarding lifespan, noise, and cost. Ball bearings offer the longest lifespan but are generally more expensive and potentially louder; sleeve bearings are more affordable but have a shorter lifespan; hydraulic bearings offer a balance between lifespan and noise.
3. Flame-Retardant Materials: Both the frame and impeller are made of UL94V-0 rated flame-retardant plastic, enhancing product safety. UL94V-0 is one of the highest flame-retardancy ratings for plastics, indicating excellent resistance to burning.
4. Multiple Models Available: The chart lists various models with different voltage (5V and 12V), airflow, air pressure, and noise levels to meet diverse application requirements.
5. Comprehensive Certifications: Certified with CUS, CE, and RoHS, demonstrating compliance with US, European, and hazardous substance restriction standards, ensuring quality and safety.

Key Advantages:

1. Flexibility and Adaptability: The multiple models and bearing options provide high flexibility and adaptability, catering to various application needs.
2. High Efficiency and Energy Saving: Compared to traditional DC brushed motors, brushless DC motors offer higher efficiency and lower power consumption, contributing to energy savings.
3. Long Lifespan (depending on bearing type): Models using ball or hydraulic bearings have a longer service life, reducing replacement and maintenance costs.
4. Low Noise (depending on model and bearing type): Some models offer low noise levels, suitable for noise-sensitive applications.
5. Detailed Performance Parameters: Provides detailed performance parameters, including P@Q curves, facilitating precise selection and design for users. The P@Q curves visually illustrate the static pressure generated by the fan at different airflow rates, helping users better understand the fan’s performance.
6. Quality Assurance: Manufactured by a reputable company (Guangzhou mega Electronic Technology Co., Ltd.) and certified by multiple standards, guaranteeing quality.
