Pond Boss Forums AERATION Systems questions Airmax vs hiblow- small pond

My curiosity got me and I reached out to HiBlow and received the below info that describes the pressure, flow, amp, watts, & noise levels throughout its practical range of use. I was impressed with their quick reply, only a few hours.

I was interested to see that its power usage goes down the harder that it is working. I suppose that the diaphragm frequency slows at higher pressures reducing its ability/need to draw more power. Kinda makes sense to me now that I have seen the numbers. You actually use less energy at higher pressures at the loss of CFM.

The noise level bounces around some throughout its operating range, but its all negligible IMO.

The 120 would be a fine choice so long as its pressure never gets above the 4 psi mark (or thereabouts). I do believe it would be happier at the 2.5 mark, but it is certainly capable of more and energy savings to boot.

Anyhow, I thought this would add to the thread.
