Full Face Snorkel T-Rex Blower PAPR (Positive Air Pressure Respirator) PPE

by k3nd0

EDIT: 4/8/20 I have added 3 remixed mask adapter files. V4a, (adds CPAP sized external tube and makes easier to print) 4b (same as 4a and opens up interior to pipe air to side chutes that service the mouth portion of my mask), and 5 (all of the above and further widens the side chute area). I have also included a plug for the center chute of the mask if you would like to close it off and only use sides. Note V3 is still good for a stand alone filter that does not utilize the cpap hose and blower parts. I have added 1 remixed file for the large cut your own filter holder which should seal much better. EDIT: 4/7/20 After test fitting several of these parts I found my cpap hose does not fit the opening on the mask adapter. I will remix this with an external tube from a previous version. Also the cut your own filter adapter doesnt seal well to the blower. I will remix the base of the 3M adapter which does seal well and the top of the cut your own adapter. Please do not purchase the parts to make these unless you need it for a person with elevated risks or to be donated to a local medical facility. These adapters allow you to make a PAPR (positive air pressure respirator) utilizing off the shelf parts that can be sanitized and reused and will assist in reducing PPE consumption. These are not my designs I have compiled them from across the internet in an effort to assist with the pandemic response to the corona virus COVID -19. If I have used one of your designs and you wish me to remove it please notify me and I will. I have attempted to credit their creators where possible. If you chose to use these I cannot guarantee they will sufficiently protect you from infection, but it is better than using a tshirt to cover your face. The positive air pressure to the mask means the seal on the face is not as important as other masks. This will allow you to use ill fitting or incorrectly sized masks in the case that supplies become limited. I recommend printing the adapters in PETG
