O2 Commercial air Pump, 1157 gph 4.64psi. Aquarium,Hydroponics,Pond pump by Elemental Solutions

Quietest pump I have ever had, super powerful and was here early. Good price

This is an extremely powerful pump. It has no problem with deep aquariums and long supply lines. Noise levels are reasonable. I wouldn't want it in my living room, but the noise is not objectionable in my fish tank area. The pump is both more powerful than and quieter than the diaphragm pump that it replaced. I found it necessary to dump some of the output air to keep the back pressure reasonableThe pump does vibrate significantly and even when I placed it on the concrete floor, I felt that it was desirable to put it on a vibration damping pad. Operating temperature is "warm to the touch" without forced air and an ambient of 67F.I have been using the pump for a few weeks and have no problems or issues with the pump.Overall I have to say that this is the best pump I have owned and I have been keeping fish for over 50 years.

Pumps a LOT of air but is quite noisy.

Overheated and stopped working after just a few hours.

Worked great but only lasted a few months and just stopped working. It is past the return date so I'm not very happy

Great quality air pump for hydro better than eco plus and the cheap chinese knock off that sellers use deceptive advertising on here to get you to buy it. Make sure it says Elemental 02 on the ad look at the handle if it looks like this its the good one the cheap ones dont last and the handle looks smaller and cheaper

A little on the noisy side but certainly worth the price

Now this is an air pump. Pumps air like it supposed too, and it quite quiet. The fish are happy, so great addition to my fish tanks.
