Liputan6.com, Surabaya - Sepuluh Nopember Institute of Technology (ITS) Surabaya made an innovative oxygen concentrator, namely the ITS Oxygen Concentrator (OXITS)ITS Chancellor Mochamad Ashari stated, ITS Oxygen Concentrator can replace the role of oxygen cylinders that are needed by the community.Oxygen has now become a rare item since the spike in Covid-19 cases in Indonesia."OXITS is expected to meet the oxygen needs of the wider community," said Ashari, Friday (6/8/2021).Fadlilatul Taufany, Head of the OXITS Research Team explained, due to the low oxygen saturation in the blood of Covid-19 positive patients, they need a high concentration of oxygen supply while the oxygen level in the air is only around 21 percent."This OXITS can produce pure oxygen up to 95.5 percent," he said.The head of the Sub-Directorate of Research and Scientific Publications of the Directorate of Research and Community Service (DRPM) of ITS added that apart from oxygen, free air also contains about 78 percent nitrogen and the rest are other gases."The working principle of OXITS itself is to take free air and purify it from nitrogen content through pressure swing adsorption (PSA) technology," explained the man who is familiarly called Taufany.Taufany explained that the air absorbed by OXITS will go through a filter first to filter out particles more than 5 microns in size.Then the air will be compressed to increase the air pressure."During the compression process, the cooling mechanism continues to run in order to keep the concentrator from overheating and improve PSA performance," he explained.* To find out the truth of the information circulating, please WhatsApp to the number 0811 9787 670 just by typing the desired keyword.Singapore sent medical aid and oxygen to help Indonesia deal with the surge in COVID-19 cases in the country.With the warship RSS Endeavor 201, aid arrived in Tanjung Priok, Jakarta, on Wednesday (14/7)Then, continued Taufany, the nitrogen contained in the air will be absorbed by the zeolite filter to purify the air.There are two column units that work alternately, namely a column to absorb nitrogen and a column that removes nitrogen trapped in the zeolite."The zeolite in OXITS can be used in the long term," he said.This alumnus of the National Taiwan University of Science and Technology (NTUST) explained that the air that is free of nitrogen content will be adjusted and regulated in advance for its pressure and flow with the existing electronics before oxygen is supplied."OXITS innovation is in accordance with WHO - UNICEF health standards," he said.
