Modern autonomous vehicles and high-level L2-L5 driving platforms typically use nearly 30 sensors, including LiDAR, CMOS cameras, ultrasonic devices, and high-frequency radars, to maintain spatial orientation. However, real-world deployment reveals a severe critical bottleneck: environmental debris and road dust easily accumulate on delicate sensor surfaces, and rainwater further contaminates them during storms. This contamination severely impacts sensing results, blinding the perception layers and compromising active safety protocols. Therefore, integrating a robust, reliable automotive sensor cleaning air blower system is absolutely essential to ensure uninterrupted autonomous safety in any weather condition.
To tackle optical lens obscuration, Tier 1 suppliers and automotive developers currently utilize two main cleaning solutions depending on the vehicle integration framework and spatial allocation:
This specialized approach relies on a high-pressure automotive sensor cleaning air blower to generate concentrated, high-velocity airflow jets. The massive static kinetic force directly sweeps across the sensor surface, instantly removing dry dust, loose sand, and ambient rainwater droplets without physical contact or consumption of liquids.
Alternatively, some systems deploy a high-pressure water pump to wash away dried mud or sticky bugs. This pump generates high-pressure water, sometimes reaching up to 1 MPa, forcefully rinsing the sensor lens before utilizing secondary air streams to quickly dry the residual water traces.
As a leading developer in vehicle thermal and fluid dynamics, our company manufactures both types of high-pressure blowers and offers blowers in different sizes to meet the complex integration needs of different vehicle models and varying sensor clusters:
Our **small high-pressure blower** is 50mm in size (such as the BA5025 series) and can provide sufficient cleaning airflow for 2-6 centralized sensors, making it optimal for local camera housings or rearview mirror pods. For full-vehicle redundancy, our **large blower** is 80mm in size (such as the BA8050/BA8060 series) and can deliver immense pneumatic output through centralized manifolds to provide sufficient cleaning airflow for all sensors onboard simultaneously.
To qualify for commercial automotive front-installation, every single automotive sensor cleaning air blower we supply is engineered to meet five unwavering vehicle-grade development benchmarks:
TKFAN high-reliability automotive cleaning blowers are widely utilized in autonomous vehicle LiDAR modules, external surround-view camera lenses, radar sensor enclosures, intelligent highway optical tracking systems, and robotic vision hardware operating in harsh environments.
