The 50 PSI Compressor by Chad Drive Medical is perfect for patients who need humidification and who would also need to receive medication by means of nebulization. This Piston operated PSI Compressor is quiet due to the unique WOB-L piston but is also able to provide a high pressure. Due to this technology the compressor is able to deliver the medication via aerosol at a particle size of less than 2 microns. The 50 PSI Compressor has a very easy to read pressure gauge making it easily accessible to the patient.
