Model SP-MD-008 · our reference
5 L/min medical oxygen concentrator with built-in nebulizer and 48 dB(A) operation
Overview
The SP-MD-008'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.
Key highlights
- 5 L/min maximum continuous flow with stepless adjustment from 0.5 L/min
- Oxygen concentration 95.5% at low flow down to 87% at 5 L/min (manufacturer manual)
- Quiet operation: 48 dB(A) front side, 52 dB(A) whole unit
- Built-in nebulizer outlet (the 'W version) plus humidifier bottle and tubing
- Portable 15.5 kg cabinet measuring 39 x 24.5 x 50 cm, with wheels, LCD and remote
