Rossmax Aero Chamber


The Rossmax Aero Chamber is a high efficiency one way valve for easy inhalation and exhalation. The universal backpiece can be used with all commonly prescribed Metered Dose Inhalers, and the anti-static spacer improves the delivery of MDI by inhibiting the adherence of the drug to the spacer wall. The soft and flexible silicone mask provided with the aero chamber has a comfortable touch and a reliable seal, and the device is latex and BPA free. It has a portable design and easy to hold, along with being easily disassembled and reassembled for cleaning. The mouthpiece cap can protect the mouthpiece from dirt and debris when the device is not in use. This device is intended to be used with metered dose inhaler (MDI) to deliver aerosol medication to your lungs. The patient can use the aero chamber in the home, or at hospitals and clinics. The chamber volume is 175ml.
