Lewisia 35W Commercial Air Pump 794 GPH Magnetic Oxygen Pump with 6 Outlet for Koi Pond Aquarium Hydroponics Fish Tank Fountain Pond Air Aeration Kit

I got this air pump to provide air-assist to my laser etcher. The cost is much more reasonable than the laser manufacturer’s alternative. So far it has done the job well. I wish was quieter but it’s not really that loud about the same as the lasers fan.

An excellent amount of air produced for an elevated 65 gallon fish tank. The amount of noise produced is not bearable. I put this unit on sponge mounts which lessened the noise just a little bit but still very annoying.

I have purchased this model twice in the last 6 years. The power is perfect for my 5000 gallon pond and it lasts a long time with every day use. I do recommend buying or building a small "pump house" to keep it covered from the elements. I have mine in a styrofoam cooler with the front and back open for air flow. The styrofoam also helps to muffle the noise as it is a little loud.

I used this pump for aeration in my hydroponics setup. It makes a huge amount of noise and lasted about a year before it became ineffective. If the pump was built with more precision and better tolerances it would have been quieter and probably cooler. As it is the parts are loose fitting with lots of slop, this allows for lots of rattle and friction causing heat and noise

This pump works great as part of my brewing equipment. I use it to aerate the wort after a 60 to 90 minute boil.

This is a very nice pump with plenty of power. I mounted it on a piece of hard foam which eliminated any vibration and made for much quieter operation. For the price it was a good deal, of course time will tell how good it really is.

This pump puts out a lot of air for the price. As one reviewer wrote, this unit likely uses more than 35W. More like 45 or 50. And it gets quite warm. Running it without any back pressure will create a loud noise that could damage the pump. Plan on re-doing the outflow with a larger diameter tube. I've been running this pump pretty much constantly for the past two months aerating a four foot deep pond and have had no problems and no reduction in output.

This pump works great. Just make sure you have an airstone attached to each line otherwise all the airflow will escape throw the closest airline without a stone. This model doesn't actually push the air as stated and is slightly lower i believe around 1200l/h if im not mistaken so do take that into account. This is quite a loud device if not snugly and properly secured using a couple screws or nails into the wall is what i did and the sound was drastically reduced. Overall works great in my dwc hydro buckets

Works great, come fast
