Re: Pressure of Airpump

Good day, This is a valid point. The Secoh pumps that have been tested by us are relatively expensive pumps that provide higher pressure at depth than most cheaper pumps. If you pump is not suited for proper pressure at depth, the airlift's yield will suffer. I wish I could tell you which pumps to b...

Re: Collector away from pond

Hello slk and welcome, Apologies for my late reply, I can only visit the site and reply using my phone for some reason. So it is a bit more difficult to keep up and reply. I'm looking into the problem (it seems I'm not the only one). About your pond. If you run a heavy stocked koi pond, 4 airlifts w...

Re: New pond powered with airlift

Hey Bartol,

Sorry for the late reply, I was busy and then became ill a couple of days ago.

I will ask Marc about the valves to be absolutely sure.

Re: Water heating from heat created from air pump

Hello, Rich is right about moving the water and eliminating anaerobic activity to some extent. I am unsure what you mean by using the heat of the air pump. The effect of the airlift on a pond that size will be minimal in terms of influencing the temperature. How many will you be using? It is said th...

Re: Off The Wall

Hello and welcome! Interesting to read about your application. Sadly I only have knowledge on the pond applications of airlifts. I do know it's possible to pump up solid material (to a certain limit of course), but I have no experience with this. What I can tell you is that a smaller diameter airlif...

Re: 50mm airlift?

Hello, I am not sure. A rough estimate would be about half the flow of the same airlift in 110mm, but I can't say we've tested it yet. If you want some idea of what flow to expect, have a look at our test results: https://www.airlift.eu/phpBB/viewtopic.php?f=118&t=15803" onclick="window.open(this.hr...

Are the rubber sleeves expensive? It may take some practice to get it right.

Re: Air Chamber

https://photos.app.goo.gl/frpSVzxmm2ndtnc37 Here's a video of the standard air chamber built with 3" pipe. I have a new to me 40w pump (eBay is so good) and at the level shown, approx 4" above water level I was running 10 gallons a minute (3600 gallons an hour). That's crazy! I don't need that much...

Re: Airlift Discharge 50cm below water line?

That is correct. The base rules for this concept to work at maximum performance and efficiency are: - No discharge head at any point in the entire system - Large transits which will allow for enough flow - A filter that has the least amount of restriction in terms of filter media - A proper air pump...

Re: Matching airlift flows

I could see a reason for two outputs: You have a raft floating bed system and a flood and drain bed system in aquaponics. The raft would maintain a constant level, while the flood and drain bed would siphon out. You'd have different flows and one would maintain water level while the other fluctuate...

Re: Air Chamber

Looks interesting! I like the airlift you already built. I realise the materials are a bit different in the United States and can be more difficult to come by in the same measurements we use. I think this is the first similar build I've seen from the USA. Your idea could work, I like your input. If ...

Re: Rich Palmisano

Hey Rich. Thanks for joining us. I'm interested to see how you will use airlift in your system. I think you chose a good pump, I've heard of these pumps but I have no personal experience. I'm guessing it's 40W? That should be more than enough for a single airlift. Looking forward to seeing your prog...

Re: New pond powered with airlift

Hey Roy, What to put on top of each small 75 mm drains in a bottom of each chamber? Thanks, Bartol Hey Roy and the rest of the gang, Just one more question. Do I leave the wall skimmer opening where is and whether I connect it with the pipe of bottom drains? Hey Bartol, You should be able to buy bo...

Re: New pond powered with airlift

Good day Bartol, I started working on some images and kept adding details and figuring things out. These should now answer most of your questions. I made everything to scale in Paint, 1 pixel is equal to 1 centimeter in real life. Since I made a number of different drawings and had to change the des...

Re: Possible collector option

Good day, Thank you for your suggestion. Is this a metal tank? Since they mention it is rust proof... It looks suitable, but those flat sides look quite small. Are they big enough to properly fit 4 inch connectors? How much do your connectors cost? Just to get a picture of what the completed collect...
