Double breath out valve for decathlon mask

thingiverse

Double Exhalation Valve for Scuba Mask from Decathlon. Install with minimal modifications. The original membrane of the mask is used as the outer valve, and a disk or glove cut from a rubber ball is used as the second membrane. A double-valve is more reliable and has some "demilitarized" space between the two valves that minimizes the possibility of any aerosol entering the mask. Improves mask isolation. \r\nBefore installation, the valve must be checked for tightness and sealing. If necessary, replace the material of the membranes, apply post-processing or reprint the model so that both valves seal reliably individually and together at any breath in. The valve has a disassembled structure for disinfection of the inner space or replacement. Also, by replacing the cover of the valve, the exhalation channel can be blocked!\r\nWhen installing, you can use silicone sealant for dismantled structures. Or glue it irreversibly.\r\nWe wish you good health!
