T-Works, GE Appliances collaborate for oxygen concentrators

As part of the initiative, GE Appliances employees assembled five concentrators with training from T-Works.

Five oxygen concentrators designed and developed by T-Works and assembled by a small group of employees of Haier firm GE Appliances are ready to be donated to those in need.

The oxygen concentrators can consistently deliver 90% oxygen concentration at 5 litres per minute. A synthetic chemical substance called zeolite selectively adsorbs nitrogen from the air under the right conditions. The device uses a process called Pressure Swing Absorption to output oxygen-rich air, T-Works said in a release on Friday.

It said the devices were designed and developed with support from a wide network of vendors and suppliers. As part of the initiative, GE Appliances employees assembled five concentrators with training from T-Works. Some of the technical challenges that were overcome include handling and packing zeolite, protecting it from moisture, thermal management and reduction of noise and vibration.
