Jet Airlift 4 different Versions

Hello youtube. This is terrarienbau berlin. I will show you four different versions of a czech airlift. I compare a standard jetift, a bent one, a turned jetlift and one with less holes in the pressure chamber.

What a czech airlift is, how it works and most of all how to build a tlh can you see in one of my last videos. Click the infobox at the top of the corner.

This here they are so our air lifts, above the standard air lift with angle, in the middle the bent one and below the turned air lift. I would like to start by showing you how to bend a pvc pipe with hot sand to build a tlh without angle.

To this I heat sand in the oven at 250 ° for about 5 10 minutes. the pvc pipe I closed down with a cork and the hot sand I fill now over a funnel into the pipe.

Only the lower third is filled with sand. There are also other variants to bend a pvc pipe, with hot water, a hot spiral or even a hair dryer, various instructions you can find here on youtube.

I then fixed the curved tube and worked with a hair dryer and toaster to get the dents from the bend. The result can be seen here.

Next I would like to show you how I have built a twisted air lifter from the curved tube. in this case, add hot sand again. This time I fill the complete tube.

Why did I build a twisted airlift? Quite simply, nothing in nature is straight and angular, I simulate here thus a true nature water situation.

Esoterics and water explorers even speak of medicinal water, which is to be produced by right-turned water and turbulence. So here is my twisted eco natural airlift, the goal here is nevertheless to ensure a liquid watercourse.

The sand in the pipe gets very hot with time, but the pvc pipe is easy to work with gloves. Next, I have to saw all air lifts at the spout about 45 degrees so here they are the first three czech jetlifi variants.

If you would like to know how I have built the standard airlift with angle click the infobox. i have built all the air lifts from a pvc pipe 20 cm high with a 20 mm diameter and all mass are identical.

After each step of the process, abrasive paper is used as usual. In this setting you can see well what I want with this little experiment. The angle in the standard air lift causes the water to break because there is a visible edge.

In the middle the curved air lift does not have this and the water should run more smoothly. right outside the turned eco tlh. you can easily recognize the edge in the standard air lift.

The pressure chambers I have also drilled exactly the same with about 60 holes 1-1.4 mm wide. 2 cm from the bottom in two rows. And here next I will show you my fourth variant in the pressure chamber spirally drilled about 25 holes.

Of this variant a viewer told me and the author swears that this air lift should be even more powerful than the standard version. What I am doing here now you should not imitate at home.

I cook here all parts to reduce the germ density. The two angles did not survive the boiling water unfortunately and had to be replaced by me. All other parts have passed the water bath well and I now begin with the assembly. the pressure chambers are fitted with seals over the bores and the standard 4/6 hose is glued into the pressure chamber.

The whole holds tight without gluing. Since I for my part repeatedly handle with the tlh I stick everything stable with aquariumsilicon. I have attached to all air lifters a suction cup with cable ties and after 24 hours of drying the air lifts can now be tested.

Terrarienbau berlin presents from left to right: the standard tlh, the 20 hole helical, the turned natural air lift and the right outside the curved the four jetlifts are operated with two eheim 400 pumps with a total of four outputs for the four airlifters.

In theory, therefore, 200 liters of water per hour should flow through each air lifter. i take them single in operation. the standard tlh with usual small bubbles, nice to watch. the tlh with fewer holes makes at first glance not so fine bubbles as the other jetlifts.

The twisted and also the curved tlh, on the other hand, are a true eye-catcher for airlift fetishists. Here the four variants in a direct comparison, from the volume and also from the performance, all the tlh presented here are nearly identical.

In order to calculate the flow, I measured the water outlet with a measuring beaker for 10 seconds and calculated to an hour. This rudimentary check I have repeated four times and I have been able to demonstrate quite accurately 700 ml of water per 10 seconds with each of the four airlifts.

Which is equivalent to about 250 liters of water per hour. All four tlh here together make according to this calculation ca 1000 l water circulation in the 54 l basin if you considers that the two pumps circulates max.

800 l per hour, you see that my calculation are only estimates. In any case, the performance is above the assumed values ​​and up to the air lift with the 20 spiral holes in the pressure chamber, I personally find all three variants ingenious.

The turned eco air lift is being long-time-tested in my 120 liter aquarium. As soon as I see medical healing water, I let you know. Decide for yourself what is important for a well-built airlift. there are no limits to diversity and imagination. i hope you enjoyed the video, thank you for watching, click here again, until next time..
