Hailea Enviro ET-80 Silent Air Pump Blower Koi Pond Aquarium Hydroponics

The pump produces a lot of air in our lake, it has only turned off once due to it being so hot here at around 39 degrees and later in the day restarted once cooler, I keep it protected from the rain and have had no issues. It is very loud I can hear the pump 40 meters away

ok

Used it to power sponge filters in 14 tanks, works well but I can't lie, it's noisy as hell.

Not as described.. states its silent on sale description.. It's really NOT, in fact it's much noiser than the one we previously used.. very disappointed..

Used on my house septic tank , great job so far

I've had this for 18months so costwise I I think that's fair. It's always been loud, and I just lived with it. I have however replaced this in the last week with a cheaper Blagdon air pump that's so silent I wish I'd done this a long time ago. I can now sleep with my bedroom window open once more. What has been strange is that during several recent heavy downpours, the air pump fills with water and trips the house electrics. This is what has led me to replace the unit. It's powerful and creates great watr movement (90cm deep), but the downside is the volume it produces.

Great price. Arrived well packed and working. Very happy.

Reasonably priced for a very powerful air-pump. However it is very loud during operations. I can hear the pump running from an enclosed air-conditioned room while the pump is inside a concrete pump house almost 15m away.
