OxiKit open source oxygen concentrator design built and validated by TATA Consulting Engineers to produce 20 LPM at 94% concentrated oxygen. TCE made adjustments specifically for India.


Focus on Oxygen Concentrator : O2C

➤    India is battling with the worst 2nd wave of Covid-19 Pandemic. 

➤    Several big hospitals across India are relying on daily oxygen supplies but they are not getting enough to keep some as backup in case of emergency. 

➤    The situation is worse still in small hospitals that don't have storage tanks and have to rely on big cylinders leading to Oxygen crises.

➤    The need of an hour is to develop portable oxygen concentrators to save lives .

➤    Tata Consulting Engineers (TCE) has prototyped an Indigenous portable O2 Concentrator using opensource Oxikit design with 100% Indian components.

➤    TCE is open to assist MSME’s who have regulatory approvals from authorities for mass manufacturing.


Targeted Outcome = 1,00,000O2C = 20,00,000LPM = 4000 MT/DAY 


Manufacture up to 1,00,000 Oxygen Concentrators in 100 DAYS

While our Efforts were triggered due to INDIAN Crisis – We believe these efforts will help countries and communities worldwide 


The Opensource movement is to enable global communities to get access to basic element – OXYGEN – and that’s a step towards aligning with the UN Sustainable development goals




Portable Oxygen Concentrator Using Oxikit Open Source For Make in India

Oxygen Concentrators: How It Works?


1. An oxygen concentrator is a self-contained, electrically powered device designed to concentrate oxygen from ambient air.

2. Utilising a process known as Pressure Swing Adsorption (PSA), an oxygen concentrator produces up to 95.5% concentrated oxygen.

3. Atmospheric air is drawn through a gross particle and intake filter before moving through a compressor.

4. The pressurised air passes through a heat exchanger to reduce the temperature before entering sieve beds that contain zeolite, a mineral material that preferentially adsorbs nitrogen gas (N2) at high pressures.

5. As each sieve bed is depressurized, N2 is released. Valves open to deliver concentrated oxygen into a reservoir where it accumulates, and from which a flowmeter can be used for measured and continuous release of oxygen to the patient at a specified flow rate


OxiKit - DIY Oxygen Concentrator


1. An open-source Oxygen concentrator anyone can build.

2. Offers 24 LITERS PER MINUTE (LPM) OF O2 WITH 92% CONCENTRATION.

3. Easy to build design.

4. Assembly procedure / videos available for ease of assembly.

5.Assembly procedure / videos available for ease of assembly

6. OUTPUT - 20 LPM+ AT 90%+ CONCENTRATION


5 -10 LPM Concentrators are available in the market. Concentrators with higher output flow (more than 15 LPM) will help to reduce pressure on existing Oxygen supplies


OxiKit Offers 24 liters per minute (LPM) of O2 with 92% concentration
