health concept into the design: Dalong commercial vehicle launched air purification system to protect the health of passengers

Recently, China's high-end customized commercial vehicle manufacturer-Dalong Commercial Vehicle officially released a new generation of intelligent air purification system, which is fully installed in its latest V9 Pro, V12 flagship series and customized MPV models. This move marks that Dalong commercial vehicles are the first to upgrade the' in-vehicle micro-environment health management' to a strategic level, enabling travel safety with science and technology, and redefining high-end business cockpit health standards.

The air purification system was jointly developed by Dalong, Suzhou Nano Institute of Chinese Academy of Sciences and Braun Air Technology Laboratory of Germany. It adopts a five-fold high-efficiency purification structure: a primary filter screen intercepts hair and dust. H13 HEPA filter element can filter more than 99.97 0.3 micron particles (including PM2.5, pollen and bacterial aerosol); Activated carbon + modified graphene composite layer strongly adsorbs formaldehyde, TVOC and peculiar smell; UVC deep ultraviolet module inactivates influenza virus and coronavirus in real time (the inactivation rate of H1N1 detected by SGS is 99.99); The negative ion generator continuously releases ≥ 5 million/cm active negative oxygen ions to improve the oxygen sense and mental concentration in the cabin. The system supports intelligent linkage-through real-time feedback from the PM2.5 sensor, CO₂ concentration monitor and temperature and humidity probe in the car, the purification gear can be automatically adjusted, and the filter element life and air quality heat map can be remotely started and stopped at the APP end of the mobile phone.

Dalong commercial vehicle, said at the press conference: 'commercial vehicle is not only a means of transportation, but also a mobile office space, family extension scene and health protection fortress. We refuse to use air purification as an optional gimmick, but use it as the standard configuration for all V9 Pro and above models, from the tightness of the body structure (12 silent seals + three-level threshold airtight design), the antibacterial coating of air conditioning duct (silver ion antibacterial rate 99.2), to the environmental protection grade of cabin materials (OEKO-TEX for all interior trim®Ultra-fiber leather and aldehyde-free PU foaming materials Standard to 100 I-class infant safety standards) to build a full-link healthy closed loop. '

noteworthy that the system has passed the full certification of the National Bus Quality Supervision and Inspection Center's "Code for Evaluation of Air Quality in Vehicles" (GB/T 27630-2023). After 30 minutes of operation in a high-temperature closed cabin at 35 ℃, the formaldehyde concentration drops to 0.02 mg/m (the national standard limit is 0.10 mg/m), and TVOC is lower than 0.4 mg/m (the national standard limit is 0.6 mg/m). The first batch of vehicles have been delivered to the International Medical Department of Shanghai Ruijin Hospital, the senior management team of Shenzhen Qianhai cross-border enterprises and the VIP reception unit of Hangzhou Asian Games. User feedback "significantly reduced travel fatigue and throat discomfort '.

, as a national brand that has been deeply engaged in the field of high-end business modification for 18 years, Dalong commercial vehicles adhere to the product philosophy of "safety is luxury, health is comfort. The mass production of the air purification system not only fills the technical gap in the field of active health protection for domestic high-end commercial vehicles, but also promotes the upgrading of the industry from 'visual luxury' to 'vital sign-level care. In the future, Dalong will continue to invest in the research and development of on-board biosensing and AI health housekeeping, with the goal of achieving non-sensory monitoring functions such as heart rate, blood oxygen and stress index on the bus by 2025.
