A This may be due to worn fan bearings or disordered airflow. Check the FFU motor's operating status and adjust the air outlet position. A data recording system (such as a vehicle-mounted OBD monitoring system) can quickly pinpoint the problem. Combined with a low-noise design (≤45dB), this can extend hardware lifespan by more than 3 years.

A Check if the installation was professional and if sealing strips were used at the joints. Regular cleaning with a neutral detergent is recommended, avoiding scratches from sharp tools. In medical settings, silver ion antibacterial coatings should be wiped with a lint-free cloth to prevent bacterial growth.

A Check the strength of the profiles and the installation process. It is recommended to use thermally broken aluminum alloy profiles with a three-seal design. As shown in the Sohu case, segmented insertion of inner steel linings can easily lead to air leakage. Overall reinforcement can improve airtightness, and using sealing tape to fill gaps can reduce maintenance costs by 40%.

A A complete seal is required, and argon gas filling is necessary. Shanghai Oujie's patented technology shows that the through-sealed aluminum frame eliminates leaks caused by cutting the sealant, and combined with a desiccant alternative, it achieves 100% anti-fogging. A filling test is required before leaving the factory, and on-site ventilation can be achieved through pre-installed pipes.

A This may be due to aging sealant or an imbalance in temperature and humidity control. It is recommended to use double-glazed windows with a thermal insulation layer (K-value ≤ 1.8W/(m²·K)) and a dehumidification system. Regularly clean the surface with anhydrous alcohol, avoiding the use of corrosive cleaning agents, which can extend the service life to over 10 years.
