What is a small blower?

Professional definition: Small blowers refer to airflow conveying equipment that is compact in size (usually body size ≤30cm), with moderate air volume (1-50m³/min), pressure range of 5-10kPa, and can be adapted to low-pressure and low-flow working conditions. They are based on centrifugal or axial flow principles and are mainly divided into three categories: AC small blowers, DC blower (including 12V/24V), and mini blower fan.

Core features: Low energy consumption (power ≤500W), low noise (operating noise ≤75dB), easy installation, strong adaptability, can be flexibly embedded in small equipment, enclosed spaces or portable scenarios, unlike the high pressure and large flow characteristics of large blower fan, it focuses on "compact and practical, precise adaptation".

Industry reference standards: Adhering to GB/T 13928-2018 "Limits for Noise of Industrial Fans" and ISO 1940-1 "Classes of Balance Accuracy", ensuring that the application scenario descriptions comply with industry standards and enhancing the authority of the content.

Selection and Usage Considerations for Different Application Scenarios

Key Points of Scenario-Based Selection

Select the model according to the needs of the scenario: axial blower are preferred for heat dissipation scenarios, centrifugal small blowers are preferred for ventilation and material conveying scenarios, and 12V/24V DC blower are preferred for portable and low-pressure scenarios.

Select based on operating parameters: Combine the required air volume and pressure of the scenario with the power and noise requirements of the equipment to avoid "using a large tool for a small task" or "insufficient compatibility" (e.g., for precision instrument scenarios, the noise level needs to be ≤60dB and the air volume needs to be 1-5m³/min).

Select according to industry standards: In the medical and food industries, prioritize oil-free and sterile small blower fan; in the industrial industry, they must comply with the GB/T 13928-2018 noise limit standard.

General Usage Precautions

Installation Notes: Avoid installation in dusty or humid environments. The air inlet of the small blower should be kept away from obstructions to ensure smooth airflow and extend the service life of the equipment.

Maintenance Notes: Regularly clean the air inlet filter and dust accumulation on the casing to prevent dust blockage and reduced airflow. For DC blower fan , ensure voltage stability and avoid overload operation.

Safety Precautions: When used in industrial settings, electrical safety regulations must be followed; in the medical and food industries, regular disinfection and testing are required to ensure that the equipment is leak-free and free from contamination.
