Best for continuous Underwater operation: Amarine made 3 inch Bilge Blower

Buy on Amazon

We would, of course, be remiss if we didn't mention amarine made 3 inch bilge blower for regular usage. It is not particularly quiet, but few blowers are, especially ones that move a lot of air. It is good as a ceiling fan if in a large space. The heat generated by the exhaust will in the very least melt the housing and fan blades and more likely catch fire.

This fan is 12volts and draws 2.5amps. It can be used in part of a larger blower system on a boat. There is an arrow on the housing that shows direction of flow. The fan is quiet and moves a ton of air. It would be easier to just turn it around as the fan blade is designed to run in one direction.

Why We Like This:

Pretty loud but totally worth the cfm and size
Operation is perfect, nice and quiet & pushes the air
Nice and quiet, moves a lot of air, quality thick plastic seems durable
