Side Configuration Valve Weight Test

A mock demand valve and diaphragm were attached to the fit test rig in order to identify any weight issues or changes in fit due to unbalance. The weight of this component was simulated as accurately as possible and equalled approximately 35 grams.

Result: 

Having this component positioned off centre - did not affect the fit or balance of the test mask in any way. Additionally, if the size of the diaphragm is further reduced it is likely that this component will have even less of an impact in these areas.

Additionally it was noted that downward vision was improved and a very minute portion of peripheral vision was affected on the right hand side. This can potentially be resolved further with testing and development in positioning and form.
