A adaptor for those Klean-Strip canistors to transfer fluids with the assist of a aquarium air pump. Still working on the threads. You can just follow the principle using any materials that are suited for chemicals and pressure.

The principle:
1) Air pump supplying air to the (preferably top) canister creating pressure buildup.
2) A sizable hose tapped to the bottom of the container. This is your output. {I recommend putting a valve on the output to close it off when done. My system is just a hose tapped through the top of the container traveling all the way to the bottom to pickup fluid. This method you dont need a valve, just place the output higher than your container. I choose this way so no weird pressure builds up when not in use. There is no free moving air to evaporate your fluid.}
3) Flow is regulated (once pressure equalizes) by hose dimensions and air supply. Increase these respectively to obtain higher flow rate.

I was surprised the flow level when pressure equal
