The Air Defense and Air Force Service under the Ministry of National Defense put two stations of mobile oxygen production equipment into operation on Tuesday at the Military Hospital 175 to meet the medical oxygen needs in Ho Chi Minh City.

Each station includes a unit of production machinery and equipment mounted on a transport vehicle and an attached mobile back-up generator, according to Colonel Nguyen Van Hieu, head of the Air Defense and Air Force Service’s motorcycle - electrical department.

Six staff members, including two drivers and four electricians, currently operate the two stations with a designed capacity of 16 cubic meters per hour.

It is estimated that each station is capable of generating from 40 to 60 40-liter extracted oxygen tanks with a working pressure of 150 kilograms per square centimeter on a daily basis.

Utilizing the pressure swing adsorption (PSA) technology, which separates nitrogen molecules from other gas molecules by the carbon molecular sieves, it creates 99.5-percent pure oxygen products.

This portable oxygen production system can be quickly maneuvered to any location, practically contributing to meeting the urgent need for medical oxygen at hospitals for treating COVID-19 patients.

In Ho Chi Minh City, Factory A41 run by the Air Defense and Air Force Service is also operating three on-site liquid oxygen production lines with a capacity of about 4,300 40-liter oxygen cylinders.

The factory donated 1,000 40-liter oxygen cylinders to 12 COVID-19 field hospitals in the city on August 18.
