Key Features and Advantages:

Main Features:

1. Small size and lightweight: The 40x40x15mm dimensions and 21g weight make it easy to integrate into devices with limited space.
2. Multiple voltage and performance specifications: Offers two rated voltages of 5V and 12V, as well as different speed, airflow, and air pressure options to meet various application requirements. Different suffixes in the model code (e.g., LL, L, M, H, HH, V, HV) distinguish different performance parameters.
3. Optional bearing types: Provides three types of bearings: ball bearings, sleeve bearings, and hydraulic bearings (HY), allowing users to choose according to different requirements for lifespan, noise, and cost in different application scenarios.
4. Flame-retardant materials: Both the frame and impeller are made of UL94V-0 grade flame-retardant plastic, which improves product safety.
5. Brushless motor: Uses a DC brushless motor, which offers higher efficiency, longer lifespan, and lower noise compared to traditional brushed motors.
6. Detailed performance data: Provides detailed performance parameter tables and airflow-static pressure curves (P@Q curves) to facilitate user selection based on actual needs.
7. Multiple certifications: Has passed CUS, CE, and RoHS certifications, complying with relevant international standards.

Main Advantages:

1. High efficiency and energy saving: Brushless motors are generally more efficient than brushed motors, which means that with the same power input, greater airflow or air pressure can be generated, thereby reducing energy consumption.
2. Long lifespan and low maintenance: Brushless motors do not have the problem of brush wear, so they have a longer service life and lower maintenance costs.
3. Low noise: Brushless motors usually operate with lower noise than brushed motors, which can provide a quieter working environment.
4. High reliability: Brushless motors have a simple structure and high reliability, making them less prone to failure.
5. Customizable performance: Multiple models and bearing types are available, which can be customized according to different application requirements to provide the best performance solutions.
6. Detailed technical support: Provides detailed parameter tables, performance curves, and dimension drawings to facilitate user selection and design.
