The 8F-5AW is Yuwell's flagship 5-litre home and clinical molecular-sieve oxygen concentrator, delivering 95.5% oxygen at low flow down to 87% at the full 5 L/min from a 400 VA Class II unit. The 'W' variant adds a built-in nebulizer/atomisation outlet, plus a humidifier bottle, backlit LCD, timer and infrared remote control. Its 48 dB(A) front-side noise and 15.5 kg body make it one of the quieter fully-featured 5 L units in the range.
