Fridge Motor Air Pump

Ca++ · Sunday at 2:53 AM

Rounding up a lot of these ideas, I had another, that I then found existed. I may of even seen it before. A water pump in the tank (bldc so near silent) and a venturi to draw air into the water flow. I have found youtube vids, and amazon sell the venturi's for pennies. It's very much like the microbubble nozzles I can't get, but lower pressure, so you get bigger bubbles. What I have seen uses just a pipe as jetting, but I feel the air could be broke up more, with a gauze to break up the air, without adding a lot of resistance.
I will have to have a play, but this basic idea seems well covered

That seems to work well, just out the box. I don't know where it's from, but I'm interested

Venturi systems work good.

Our Emergency bilge system was venturi based. If ingress of water was too much for normal pumps to keep up, we would open venturi lanes off the 10 Bar fire main that would create suction, AKA a venturi, to help remove water.

Air vaccum generators work the same way creating a vaccum from pressurized air or water flowing by.
