Durability components under high O2 concentration

GOAL

The purpose of this test is to test the durability of the components present on the ventilator at high O2 concentrations. The components that have been tested: the bellow, two connections of different materials (PLA and PET) and some aluminum plates (1000 and 6000 series).

SETUP

The test setup consists of a box in which the components and an oxygen sensor were placed. The container is made hermetic by a plexi plate and mastic.
The oxygen sensor was controlled with an arduino and with this we could measure the oxygen concentration that was present in the tank.
