The unique combination of the new OMRON CompAIR compressor nebuliser with the Virtual Valve Technology (V.V.T.) nebuliser kit means that more of the aerosol is a respirable size and available to the patient to inhale. The V.V.T.’s unique design results in less parts that could be lost, less parts to clean, higher hygiene and easy maintenance. When not in use, the V.V.T. nebulizer kit can be fixed on the main compressor unit.
The Comp Air is a medical device.
