COVID Vaccum Formed Mask · 模型 294926
This mask was developed at the Federal University of Technology – Paraná. It is intended as an emergency only option for N95 mask. USE IT AT YOUR OWN RISK!!! This design has not been certificated and I do not take any responsibility for its use - This model is intended to be thermoformed or printed (and post-processed for porosity control) - A filter material has not yet been defined. The aim is for a 95% PFE - The material must not have a high resistance to the breathing. Otherwise, a proper seal will not be achieved. - An Edge of rubberized material can be added to improve on the seal - The prototype was made in 0,7mm Flexible PVC This work is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License.
