Snowflake Posted September 22, 2022 Share Posted September 22, 2022 Hi folks I made this contraption to save on O2. It's seems to be working so far perfectly. Easy trigger. Just thought I would throw this out there to help others save when exhaling as we lose alot of o2 during this time. Flow rate I'm using is 8 litres per minute. I used the trigger from a plant sprayer. Works well. Good luck if you are looking to do the same. Use zip ties to get it to hold tightly at the main sections.
