Heavy duty inflator/ deflator pump
An invention I have devised requires the existence of a 12 volt air pump- not the air bed type- something a bit more serious, that I can lead to a spider of 4 pipes semi permanently connected into a RIBs 4 valves. I need at the flick of a switch to be able to inflate the tubes fairly rapidly- say a couple of minutes for a 5 metre boat from flat so it needs to be heftier than an airbed pump. Importantly I then need to be able to set it up so at the flick of a second switch (both switches has to be remote from the unit- probably on the dash) suck all the air out again so the tubes are sucked flat (ish).
I know this is highly unusual for a RIB. Unfortunately as it is an unpatented invention I cannot explain what the whole thing is trying to achieve. (I hate people on forums who say this)
Any ideas? I know nobody with a conventional RIB would really want to do this (unless it was for smaller storage at the touch of a button after use?- which isn't what my idea is)
Can anyone think of other industries/ users of low pressure high volume air pumps that would need this sort of device or something similar that I could take apart and adapt? My preferred route would be to adapt something existing, mass produced and cheap, rather than commission a bespoke pump to be built, although I'm sure plenty of pump mfrs could do that for me.
