A brief overview of this ingenious method of compressing air using only the power of water.

The way a trompe harnesses the power of water to generate compressed air with no moving parts is fascinating and its use is seeing a small revival in modern days. A trompe can be useful in off-grid aquaponics and hydroponic systems that need aeration of the water. And, in fact, the inspiration for this video came from the late Bruce Leavitt, a mining engineer who pioneered the use of small trompes for aeration and treatment of mining water in remote locations without access to electricity.

      With not moving part? But the water is Moving

    This is so cool! I may build one for my fish tank using a tiny ram pump to power it! It may be enough to run my air stones and is WAY cooler than using a dedicated air pump. Louder though.....

    Would introducing a vortex into the "intake " side have any effect?

    Grady, this isn't a critique i just wanted to let you know that I love your videos. Being able to use your videos to explain things to my friends is something I love to do. Keep up the inquisitive attitude and the phenomenal video quality considering your budget. I've been watching your videos since your garduino video and it makes my day when I see a new video from you recommended to me by youtube.

    Practical Engenireering: "No moving parts!!!" Also practical engeneering: "moving water through a pipe..." I think you missed one moving part XD

    y can't we run the air compressor directly with energy of the falling water

    Only works if you have a source of large moving water and a dam or large drop in elevation

    In sugar production in Brazil they use a similar design to create vacuum, that is a important step to the sugar crystallization.

    could you also create low air preassure (vacuum) on the "air intake" side?

    My home town is Cobalt Ontario, I have been to whats left of Ragged Chutes many times buy never got to see it vent. Some Kids burned down the pump house when I was a kid and the video that you show in your intro hasn't happened since the 60's to my knowledge.. So thank you I always wondered what it looked like and now you showed me video in your intro. Cobalt is an amazing town. We would explore the old mines and tunnels as a kid and the pipes from ragged chutes are everywhere in the bush all grown over from a 100 years ago the main lines are over 12 in in diameter. So much power was always amazing to me..

    Ok dumb idea what if you use the water hammer pump with this and use the air to supply O2 for the fire (I'm not sure where I'm going with this but i will be keeping this in mind

    So would it be feasible to cool a building with a trompe that drew warm humid air from the building and mixed it with a hydraulic RAM pumped liquid desiccant,CaCl (road salt) +water solution,circulated from a reservoir buried below the frost line and releasing the dehumidified compressed/chilled air back into the building? All plumbing,reservoirs,and pressure tanks being non-corrosive PVC or PEX?

    I would have liked you to have included the math used in this and some of the information of how high the PSI was able to be obtained by this system. Also would have been nice to be included, was the cubic volume that was made per hour at some of these plants. Great video.

    considering you have water running through it wouldn't that be a moving part

    Wrong title. Water IS a moving part. No air - and no fluid at all - can be compressed without a moving part and an energy source (in this case, gravity). The correct title should be "compress air without artificial moving parts". Or sort of...

    I worked on a vacuum pump one time that rings a bell here. It didn't compress air but the vacuum on the intake side was useful in the lab. It worked ok but not great.

    Next step is find a way to connect the output water to its input. Waste less water! (If only that would work for infinite perpetual energy :P)

    love this. it's quite hard to see the pressure gauge, but do you have an estimate on lengths and pipe size you would need to say, fill a bike tire at roughly 7 bars?

    so water isn't a "part" then i guess?

  • solomon mallela

    I have a doubt, why can't we compress the air like a turbocharger , using water instead of exhaust gas It will be so much powerful I guess ! Then let the same water cool it down through exchanger I've seen a lot or water flow off for a very little compression.

    this is fascinating! the first part of the trompe, is just like reverse of sponge filter we have in aquarium, where the trompe use water to move air and aquarium sponge filter use air to move water

    Theoretically ancient Egypt could have had working air tools ( chisels, hammers, etc) if they built one of these.

    This is very cool - it reminds me of the Sprengel vacuum pump, which is exactly the same (except exactly opposite, and also full of mercury). And indeed the Wikipedia page on the Sprengel pump says that it's a modification of the trompe.
