More Noise Than Claimed in Brochure
Sleek design. Easy mounting. Made in China. Well-balanced fan blade. Very low current draw for CFM of air moved. Motor emits a medium-high whine, similar to a hair dryer. Definitely NOT whisper quiet as claimed in brochure. I added 10 feet of sound attenuating insulated flex duct and mounted the fan in a separate space to bring the noise level down to an acceptable level. Now I only hear the noise of air movement normal to a unit this size. Manufacturer would do well to include sones or dB levels in specs and in brochure. Unit has a 110VAC corded plug so it could also be used as a stand-alone air movement fan (similar to a carpet fan).

Moves a lot of air
I purchased this inline duct fan to resolve heating/cooling issues in our master bedroom above the garage. I installed the fan on 5” duct work and used 2 feet of insulated noise reducing flexible ducting. Only place to install the fan was about 3 feet from the take off duct at the furnace, where the fan has to move it about 20 feet to the bedroom register. Atmosphere website has full specs for the product which I used heavily to research my purchase. The 10 year warranty also moved me to this purchase as well. Solved our heating and cooling issue and moves a lot of air. Very low noise from the unit it self. No vibrations from the unit - I did place neoprene on the mounting bracket as a precaution. Only noise is a massive increase in air flow to the bedroom. I also installed atmosphere’s varispeed triac switch, since I needed to turn the fan to low-Med because it works too good. Overall I’m very happy with my purchase.
