What AUTOMAN Could Do When Facing the New Coronavirus?

The World Health Organization (WHO) has declared a global health emergency over a new coronavirus which causes an illness officially known as COVID-19 that has killed more than 3,800 people worldwide (as in March 10 2020).

It was first detected in China. On December 31 2019, China alerted WHO to several cases of unusual pneumonia in Wuhan, China. The virus was unknown. On January 7, WHO officially announced they had identified the new virus. The novel virus was named 2019-nCoV and was identified as belonging to the coronavirus family, which includes SARS and the common cold. Medical experts have not yet determined where the virus originated.

No matter where it is from, people from all over the world have worried a lot and start to combat with the disease. By March 7, the coronavirus had killed nearly 3,600 people and infected another 102,000 people across more than 90 countries.

From the statistics we could learn that China’s new cases are reported down from 143 to 99 with a total of 80,651 cases nationwide. Official data, meanwhile, showed global cases outside China have increased dramatically over the weeks.

What causes this reverse happen? Does it because people in China all wear masks? Maybe. Or they stopped to go to work and were required to stay at home? Maybe. Or they have secret medicines? May not be. As the auto professional, we have also paid our attention on the special vehicles local hospitals utilize to prevent virus spread – The Negative Pressure Ambulance (NPA).

NPA is also called “Mobile Mask” – its main task is to help those who with severe infectious diseases. During the months, a huge number of NPAs are made and delivered to emergencies and hospitals nationwide. They help to protect the medical workers from being infected during the transportation. NPA is the first barrier of preventing virus spreading.




Unlike ordinary ambulance, NPA can provide negative pressure isolation function. There is an independent isolation medical cabin in the car, which has the characteristics of antisepsis, isolation, ventilation and bacteria resistance. It can disinfect and filter the air exchange inside and outside the car, and kill 99.97% of the bacteria.

Technical explanation: The negative pressure device makes the air pressure in the car lower than the atmospheric pressure outside the car, so that the air can only flow in from the outside of the car, and the incoming air is sterilized and then discharged out of the car. Before the air in the vehicle is discharged, it will also be filtered by high-efficiency filtration (99.97% @ 0.3um) to avoid the pollution of the external environment caused by the discharged gas.

At this time, the negative pressure medical cabin in the vehicle forms a fixed circulating air area. The treated air flows from the clean area to the infected area (patient area). At this time, the air pressure in the negative pressure medical cabin is between - 10 Pa and - 38 PA, and the air change is about 20 times an hour.

In addition to the good isolation and ventilation characteristics of the negative pressure ambulance itself, it also provides a solution of negative pressure isolation cabin for the highly infectious patients. In this scheme, the patient is completely placed in the negative pressure isolation cabin, the gas exhaled by the patient in the isolation cabin is filtered and then discharged to the medical cabin, and the air in the medical cabin is filtered by the negative pressure device and then discharged to the outside of the vehicle. This solution solves the problem of cross infection of patients and medical staff in the same room, and also solves the risk of infection of other staff in the process of patients being transported from ambulance to hospital.
 We have different models/brands NPA modified from special vehicles for various demands & budgets. Here are two most popular types.

Economical Class: CHTC C5 Modified NPA
(click pictures for detail information)

Professional Class: Mercedes-Benz VITO 2019 Modified NPA
(click pictures for detail information)

Take Mercedes-Benz VITO 2019 Modified NPA for example, the dimension is 5370*1928*2315mm, the wheelbase is 3430mm, the curb weight is 2571kg, and the body height and curb weight are increased compared to original copy. The vehicle is equipped with a 2.0T gasoline turbocharged engine, matched with a 7-speed manual automatic transmission, with a maximum power of 155kw and a maximum speed of 185km/h.

In the cabin, all kinds of professional equipment are placed in a proper place in an orderly manner. Facilities in the car are composed of 10 parts, including lighting system, air conditioning system, electrical system, oxygen system, seat and stretcher system, safety communication facilities, medical equipment, special devices, intelligent management system and on-board materials.


Facing the global-spread virus, Chinese government & people have made their contributions, together Chinese auto men also play their important parts. The experience could be learnt and copied to prevent more infected, let us know if you need to have the NPA.

BTW, if needed, we could also help providing face-mask manufacturing machine & related raw material.

We are unite & win the combat with the virus!
