SEAFLO in-Line Marine Bilge Air Blowers- 12V, 3 or 4", 130-270 CFM Ultra-Quiet Operation 4 or 3 Inch for Yacht/Sailboat/Boat- ISO 8846, CE & RoHs Certified - 4-Year Warranty

This thing is a monster LOL it really does put out a large volume of air from such a small fan I'm using mine for cooling the amplifier to my car audio system and it absolutely does exactly what I needed to do!!! And plus where these things are made is not too far from where I live so that's pretty cool too!

In the open air you can hear the fan. However, we must highlight the fan really moves thecair! We are happy with fan performance overall. For our application we will keep an eye out for a four inch fan that is quieter and moves similar air, while also looking for one that is rated for continuous duty. We want to stress our use case is not an air bilge pump... as an air bilge this fan should be fantastic!!

Great blower quiet

Full blower & not a lot of noise! Works great on our boat!

Worked fantastic

Very good product, second one I have bought.

Good blower all things considered. I bought this unit and THEN I did my research...This blower is not being used as intended by the manufacturer. Larger amp draw than some of the competitors. This bilge blower should only be used on a boat or for DIY projects that do not require it to be running for extended periods of time. I bought this blower for a DIY spot cooler but discovered through my own research that these units run for years as intended but a reoccurring theme was popping up in every review forum/etc, when run for long stretches (like DIY spot coolers) it's lifespan can be drastically reduced. I kept the blower but purchased a blower much more forgiving of long run times. I used the SeaFlo for something I always need but don't want to buy (DIY kinda guy); a portable fume extractor for my soldering projects. As a fume extractor, it is run briefly while soldering then shutoff in between which is similar to what it's intended by the manufacturer to do. Would recommend it for boating/fume extracting. Stay away if it's the icechest air cooler yer working on.

Granted I bought this fan for an alternative use, making a custom carbon air filter where I needed a quiet in-line blower fan that could move 270cfm or so. But what I found was this fan motor is definitely not the "ultra-quiet" it is so heavily advertised as. With ambient 42 decibels I measured this fan at full bore 12.1v, 54w, a screaming 91db. It's easily as loud as a hair dryer. It moves a lot of air and if its buried in your boat's engine room you probably wont notice much but if you're looking for a truly quiet blower fan you might look elsewhere. On the plus side it does move a lot of air, in fact I measured 520cfm, almost double what was advertised. This was with no ducts connected which probably improves air speed from their measurements.

un peu bruyant

all good the product is genuine and working fine

My old used 1990 cabin cruiser came with a decrepit and siezed-up Attwell blower when I bought it in 2021. I managed to get it running again with some oil on the bushings but it was always a bit noisy. I decided to replace it this year and had good experiences with SeaFlo products before so I chose this one even though it wasn't the very cheapest. I was a bit worried when a reviewer said it was noisier than they expected, but I found that not only does this unit push a lot more air that my old 4" Attwell, but it is quiet enough that a passenger on my boat yesterday worried I had forgotten to run the blower before starting the engine, even though he was sitting directly over the engine bilge.Also I was lucky that the new SeaFlo mounting holes lined up with the old Atwell ones so I didn't need to drill new holes in my transom.

Not good

Works as advertised
