AquaMiracle Linear Air Pump AP-40/AP-60/AP-80/AP-160 for Pond Aeration, Septic Air Pump, Hydroponic Air Pump, 635/950/1350/2550GPH, for Pond, Waste Treatment, Aquarium, Fish Farm, Seafood Restaurant

First, noise level and airflow: as a caveat, I don’t have an actual airflow meter. That being said, a single one of the 160lpm units has enough power to churn 4 cubic feet of K1 media in a 275 gallon IBC tote for a moving bed bio reactor. Value: It absolutely pumps more than my 80lpm Alita pump at a lower price point, so to me this unit gets you your bang for your buck. Installation was super easy, took less than 3 minutes to switch out my old pump. Puts out a little heat but nothing crazy. Less noisy than a backup Blue Diamond pump I have. External build quality is good, hard shell (metal?) with enameled paint. Now, I did say I bought it twice. First unit died after about 2.5 years in operation. That was entirely my fault: we had recently adjusted our sprinkler heads, and it was spraying directly at the unit from the side, which is not what these are meant to deal with. Outside of that, the unit ran flawlessly and continuously for those 2.5 years.

It worked great for the first few months then lost all air pressure. Can't seem to find a rebuild kit for it. After contacting the seller they agreed to send a replacement diaphram which I am so pleased with will do business with this vendor again in the future as I do love the pumps

Exelentes.

I've bought 2 of these neither one lasted a year. Both tore the diaphram. The company sent me replacement diaphrams. I replaced them and they work correctly they were dry and surface rust. I greased them. I suspect that was the problem. There was no oil on the metal parts. They made it right

Worked for less than a year and than just stopped working and got crazy hot and is making a terrible burning smell. Thankfully I found it before it lit on fire.
