Questions & Answers
I've been boating for 40 years, and it's no louder than any other blower in my opinion. It is undeniably audible. I have one for an engine blower and one for a head blower, both of which are operational. I wouldn't want to be in close proximity to one, but they do an excellent job. The voltage is also a factor that influences sound. They're quieter at 12 volts than 13 volts. 8 volts. So they're quieter when they're just running on battery with the charger turned off. The turbo effect noise is present because they are tunnel blowers, but it is less than the old squirrel cage design, in my opinion. br> No issues with the engine or the head. To me, the sound level is comparable to that of a kitchen exhaust fan.
Attwood claims that it is 2. At 12 volts, 6 amps are available, and at 3 volts, 3 amps are available. At 13, 1 amp is used. 6 volts. In case you didn't know, a battery typically weighs around 12 ounces. At rest, it has a voltage of 4 volts and has a voltage of around 13. When the engine is turned on, the voltage drops to 6 volts. The alternator on a car is usually set to provide 13 volts. The maximum voltage to the battery is 6 volts. As a result, in response to your question, I'd say 2. 8 amps
It'll fit inside a 3" cpvc pipe, so use that to connect your fittings.
In the event of a gasoline spill, the blower exhausts the air. Because the engine compartment is not a sealed system, it eventually draws fresh air in from various places. It could be used to supply fresh air to a sailboat or cabin cruiser below decks.

EXACT replacement for my 2003 Wakeboard boat's bilge blower fan, complete with color-coded wires. Installed the fan and checked it for proper operation before connecting the top hose to the fan that vents gas fumes overboard. Except for the fact that the motor was in reverse, everything worked perfectly. Rather than sucking air out of the engine compartment, the fan was blowing it in. After reversing the color-coded wires on the fan, it began sucking air from the bilge as intended. When I contacted the Attwood factory, they confirmed that the fan had been factory-wired in reverse. Others, one can only assume, have been wired incorrectly as well. Before finishing the installation, make sure the fan is rotating properly. The fan would get a 5 star rating if it weren't for that minor installation flaw (MAJOR SAFETY FLAW).
This is what I use in a 16-tap keezer to circulate the cold air and keep the kegs and tap lines at the same temperature. Because I need to draw cold air from the bottom of the keezer up, the fan assembly is pointing down. This will help with natural convection currents caused by temperature differences. This has an insulated brush motor, but as with most wearable items, the brushes are usually the first to go. A DC motor controller controls the fan's speed, which is kept low in comparison to its full power. For my application, the fan is far too powerful. Its surroundings are similar to those for which it was designed. The high humidity, on the other hand, eventually took its toll. Still, it's a well-made product that I'd purchase again.
It was difficult to find a motor with a small diameter that could move air while driving an impeller. Many early Ferrari fan motors are only a fraction of an inch longer. Instead of rewinding an original Spahl blower motor, I simply modified this one to fit INSIDE the original motor case. It can easily cost over $500 to rewind an original motor. When used as a cost-effective and high-performing unit, the price, value, and performance of this motor tip the scales. I also made certain that there was adequate ventilation- Support is provided by air flow and copper heat sink mesh.
This isn't the case at all. My older Seaflo had a decibel level of around 78 and sounded like a car at idle. This one is 83dB and has a higher pitch, similar to a sport bike at 12k RPM. br>br>I'm returning it because of the sound; I use it indoors for a hobby spray booth, and it sounds like after 5 minutes of sitting next to it, it would become irritating to listen to.
Only a relay switch or an off/on switch will work. When I tried to run it off a remote signal from my aftermarket headunit, it created a ground loop and turned off everything except the fan. Also, when the fan did turn on, it was much louder than I had anticipated, to the point where I couldn't hear anything else but the blaring fan.
It helped me construct a swamp cooler for my plane. When combined with a strong-willed partner, the result is a powerful combination. I've got a great cooling system thanks to a sonic 12 volt sealed battery and a switch.
I recently purchased my third and installed the second, which I had purchased as a backup. When run at less than full speed in dry conditions, the first lasted just over a year. They're quite loud when running at full speed, as other reviews have mentioned. I put mine through a PWM controller set at around 2020 mostly because of the noise. There is some vibration, so I had rubber mounts. When wiring the same way as the original, my backup went in a different direction.
The old plastic vent tubing that self-destructed on me was the problem, not installing the blower. br>I've put this unit to the test in terms of water resistance because my boat has had a slow leak that has flooded the bilge on several occasions, and once I even turned on the blower before realizing it was submerged. It still works, but it makes an unusual noise, so it might not be long before it needs to be replaced:.
