My colleagues provided the info to two optimized containerst that gone through various pressure tests and ready for usages. It bit high on prices.Agreed. Curious to see what you and @oldandlively come up with. In my line of work, I come across different types of healthcare products and manufacturing supplies.
I have been snooping our manufacturing site to see if there is any type of containers that I can repurpose for a larger water trap.
The manufacturer for one has not gotten back to me for specific questions yet. Lower costs, but not enough info to be trusted yet:
I'm also requesting info on this as well, since we used this in the fields quite a bit back in the days. Pressure back the maxed out at 8inHg without over pressurizing the lungs. Nowadays, they're pushing even higher for collapsed lungs:
Compared to what is commercially available vs your our own rigging, so far, our rigs are holding out quite well. 5 days of continuous vacuum pressurization at 15inHg, with usages in betwen, no issues. My total rig was $25. Adding time to mod and shop around, you can say it's $50.
