It's an custum made endless belt filter,
Inlet: 3x 160mm for bottom drains, 1x 110mm for skimmer
Outlet: 1x 315mm
Belt: 100µm Sefar mesh
Max.: 100.000 l/h

I use the filter for 60-65.000 l/h therefore I have 2-3 cm difference only before the next cleaning.

Besr regards,
Frank

Ok. Why you are going to replace the crielsieve?

Hello Frank,

the best thing would be a strong pump to blow the muck away. A pressure washer could also help.

Well done!

How many liters do you move per hour?

Frank

Hi,

have you had the chance to test?

Thanks

The "90 degree bend downwards" will reduce performcance compared to usual airlifts, right?

Hi Ron, until now I am a friend of membran airlifts. With less air I get better results. Therefore I compare two cases of membran airlifts at the same enviroment: a) 2 x 160 mm airlift with 45 l/min air or b) 1 x 200 mm airlift with 90 l/min (2 air pumps parallel) Both airlifts with the same length ...

20.000 l/h with 12 Watt you could reach without delivery head from my point of view. In a real filter configuration with 5 -10 cm delivery head the yield should be less, isn't it? Since the Secoh SLL 20 is not produced anymore, which air pump should be used for the pressure chamber to reach 20.000 l...

Ok, here are some more issues: T-Pipe Is there an output differenz between an airlift with a short pipe outlet (e.g. 10 cm) compared to an long outlet with two T pipes? Single vs. multi airlifts (membran type) Goal is e.g 50.000 l/h. Is it better to use one big diameter airlift (200 mm) or two small...

Hi Roy, I have a suspicion that airlifts work best at summer time with high air temperature. This is what I saw serval times. Maybe the reason is the lower densitiy of warm air compared with cool air or the air pumps are a little bit more efficient at higher temperature. Could you check if it's poss...

Ok, thanks Roy.

I changed form the first version to the second. The result at my pond is nearly the same.
