How to Select the Right Blower? The 7515 Blower Offers Solutions

I. Three Common Misconceptions When Choosing a Blower. How Many Have You Fallen Into?

1. Blindly Pursuing High Speed

• Misconception: Thinking that the higher the speed, the better the heat - dissipation effect, while ignoring the costs of heat - dissipation and noise.

• Truth: For every 10% increase in speed, the noise increases by an average of 3dB, and the motor life is shortened by 20%.

• 7515 Solution: It adopts a dynamically - balanced fan blade. Theoretically, at a voltage of 5V and a speed of 3500 revolutions per minute, it can still maintain a silent level of 39dB. With oil - bearing, the service life can reach 30,000 hours.

2. Confusing Airflow with Vacuum Degree

• Misconception: Only paying attention to the nominal airflow (CFM) and ignoring the decisive role of vacuum degree (Pa) in suction.

• Truth: The suction power of a vacuum cleaner = vacuum degree × airflow. Both need to be balanced and optimized.

• 7515 Solution: Through the design of a turbine fan blade, the vacuum degree is improved. At a voltage of 5V, the theoretical airflow reaches 5.68CFM, and the suction power is 30% higher than that of traditional models.

3. Ignoring the Application Scenario

• Misconception: Choosing a general - purpose blower, resulting in volume conflicts or performance waste.

• Truth: Handheld vacuum cleaners need a thickness of ≤15mm, and industrial models need to be resistant to high temperatures and high - frequency vibrations.

• 7515 Solution: It has a size design of 75×75×15mm, which is suitable for ultra - thin bodies; it supports high - temperature operation and has passed a 100 - hour continuous vibration test.

II. Material Innovations

• Impeller: Adopts environmentally friendly and flame - retardant PBT material, taking into account both strength and safety.

• Case and Magnet: Selects high - stability alloys to adapt to high - speed working conditions.

III. Process Breakthroughs

• Silicon Steel Sheet: Through ultra - thin cutting and multi - sheet bonding technology, the heat - dissipation efficiency is increased by 30%.

• Ball Bearings: Originate from precision manufacturing in Japan. Theoretically, the service life can reach 50,000 - 80,000 hours.

IV. Customized Design

• Lead Wires: Support length customization to meet the space requirements of different devices.

• PCB: Uses imported chips to ensure long - term stable operation.
