Air pumps in parallel

[Frank]

What do you think about smaller air pumps in parallel?

Hey Frank,

To me it seems like multiple smaller pumps will always give better efficiency than one large pump. As measured in our tests. I don't think you can overcome this difference with any of the airlift types we know of. If I were building a pond where I would need a flow of 45000L per hour for example, I would always use three small pumps with three airlifts instead of one big one with one large membrane airlift.

Do you have a different experience?

Thanks, that is my result too.

Best regards,
Frank

It seems like everyone recommends one air pump per airlift. Why is that?

I already have a larger air pump, so I was think of splitting the output to 2 airlifts.

Thanks
