Hey Subdudes, I ment to mention this earlier in the over pressure valve thread but got buried under a mountain of copper slag. I've been looking at picking up on of these little vacuum generators that run off your compressor for my vacuum bagging and infusion molding projects. So it came to mind that with a check valve attached to a thru hull on the inside of a sub and then one of these vacuum generator attached to it. That one could use the high pressure air on board a sub as a means to power the unit for removing extra air pressure inside the sub at depth, and/or remove air from inflatable ballast systems when at the surface. If it works, then you don't need a electric high pressure air pump for removing air at depth. So from that point it would be interesting to see if it was more effiecent to use compressed air to remove air or battery power in order to make a informed desition. For me since I plan to get the subs interior wet at depth, having a not electric unit that I might not need to protect from water and pressure might be better. http://www.fibreglast.com/showproducts-category-Vacuum+Bagging+Equipment-19.html#31 http://www.smcetech.com/CC_host/pages/custom/templates/smc_v2/prodtree_branch_group_2.cfm?cc_tvl=&cc_nvl=((CC,smc,V_P_US,Node_29411))&CFID=31058&CFTOKEN=39114736&jsessionid=f2309b904933f89d09586a7212335f17622c http://www.smcusa.com/sections/products/vacuum.asp I had also considered using a cordless shop vac, like Dewalt makes for removing the air from my inflatable amas when on the surface. I also was wondering if this unit or a similar one could be used to remove water from my VBT bladder(s) and put it outside the sub at depth? Regards, Szybowski |
