Kroeber 4.0

The Kroeber 4lpm concentrator is designed and built by the finest German engineers. It comes with a built-in humidifier bottle and only weighs 16kg, meaning it can be more portable than standard concentrators. Also the 0.1lpm digital increment makes it ideal for very low flow-rate regulation, ideal within children’s hospital environments.

Plus it is very quiet and easy to operate!
