VMO RESPIRATOR V4 (MASK)

 

INSTRUCTIONS:
I recommend doing the Horizontal Expansion Test, to verify if the printer is correctly calibrated, before printing the parts 

TEST: HorizontalExp.stl

1.- Print all parts

(Included two sizes of Mask, I recommend start print with size M)

2.- Past part #2 with part #3 (Filter) using SUPPER GLUE
3.- Make 80 mm N95 filter or 80mm HEPA filter
4-  Make two 80mm FELT filter
5-  Assemble the filter: FELT-N95-FELT

I recommend use VASELINE in all threads, and screw several times back and forward, to loose the threads.

6.- Screw part #6 on the mask
7.- Put Nitrile, Rubber, or Plastic 50micron
(Exhaust Valve) OD: 54mm ID: 31mm

8.- Screw part #5 on #6

9.- Cut two elastic bands (15mm) length 60cm and put part #4 with elastics, and the FILTER on the mask.

10- Cut FELT OD:50mm ID: 22mm (Exhaust Valve Filter)
11- Screw part #7 with filter from inside

You can make your own SILICONE sealer using the MOLD included or this other alternative:
