Simple Deluxe Air Pump Adjustable Air Flow Outlets with Airline Tubing for Aquarium, Pond, Hydroponics Systems

Workhorse. It's not quiet but not loud. It pushes a lot of air and runs a tad warm. Does what it should

I am using this pump for a laser engraver air assist (to blow air over laser beam burn point to blow fume particles away from laser lens and material being engraved or cut). I was surprised how quiet it is for this purpose in a garage or shop. Late night operation is not heard in an adjacent room separated by simple drywalled wooden stud walls without insulation. (The hum might be objectionable in a quiet bedroom or livingroom.) The unit is well designed acoustically as I could not find a way to reduce the noise by grasping, squeezing, hanging, or placing it on foam or rubber pads. If the noise is objectionable, the only way to reduce it would be to isolate it (enclosing or relocation) It blows plenty of air but it has almost no air pressure. If your hose has a kink, or high airflow resistance, it will not deliver air. Placing my finger over the hose ends offers no resistance at all.It is surprising considering the volume of air delivered with the hose end uncovered.

Powerful no problem at all

This sucker is loud as a weed Wacker definitely not for indoors at all and it gets very hot

These are unbelievable, compared to ordinary aquarium pumps you usually see, the pumps I was previously using were rated for 30-60 gallon tanks. These seem to move 10x the air. As some have mentioned, they're fairly loud, but so are NASCAR cars compared to your family car. I probably wouldn't want to use one in my living room or bedroom, but in the application I'm using it for, it's not an issue. 10 stars for my purpose, the water looks like it's boiling, and I only have 4 of the 6 outlets hooked up. High quality soft rubber hoses included, unlike the hard plastic usually supplied, very easy to get on and off fittings.

These things are total garbage. They over heat even when not running. There is something fundamentally wrong with them as the unit is too hot to touch even when not running. I was actually concerned there was a fire hazard. I've returned and exchanged 3 of these, and they're all the same. Beware.

This pump worked great as air assist for my laser engraver.

I ordered the pump to use on my aquariums for ease of use. It seemed to be a very powerful and efficient pump, which I tested for only about 5 mins, when i received it just to make sure the power and air flow worked. When I was ready I did my set up and all the necessary connections to my tanks, however the pump only stays on for about 20 minutes, it gets hot and shuts down. My window to return the pump has closed because I did not use the pump within close proximity of receiving it. I'm a bit disappointed cause now I'm back to square one.
