Risun designs the air filter assembly using professional simulation software such as CFD, optimizing the flow field, structural strength, and noise reduction performance;

After the prototypes ready, performance tests such as intake resistance, filtration efficiency, and dust holding capacity will be conducted through Risun's air filter comprehensive test bench and professional noise data acquisition system. And product structure could be optimized based on the test results of vehicle manufacturer;

According to customers' different requirements for air filter intake flow, Risun provides various filter material selection solutions to customize air filter assemblies. Strictly control the production process to ensure product consistency.

Air is crucial for the combustion process, as it reaches the engine through the intake system. A good intake system ensures clean, uniform, and low resistance air flow, thereby increasing engine power and improving fuel consumption.

in 2012. "Guangxi Vehicle Intake System Engineering Technology Research

Center“ in 2017

A special waterproof structural design ensures the system operates properly in wading conditions, prevents liquid water from entering the engine, and enhances safety and reliability.

CFD analysis technology is used to precisely design the flow field, creating a smoother air path. This improves intake efficiency, enhances fuel economy, and reduces system energy consumption.

Ensures that the sensor placement meets measurement accuracy requirements, guaranteeing the accuracy and stability of data acquisition.

Integrates the design, simulation, and testing of sound-absorbing materials and silencing elements to effectively reduce intake system noise and improve sound quality.
