Review on 🌀 Soleaire Super Monsoon SA-SM-1HP-GY: High-Performance Air Mover Blower Fan for Carpet Cleaning, Floor Drying, and Water Damage Restoration - CE Certified, Gray by Josh Sheehan

Looks like a very solid fan. Very powerful. The included manual lists 4050 cfm (less than 4200 in the promotional specs) and draws 11/12/13 amps on low/mid/high as opposed to the 10 amp max in the promotional specs. It's quite loud, but I think it's generally to be expected from a device that produces this type of CFM. I have a unique application for these fans shown in the images. as an attic fan, blowing air through an 8" passive attic fan. I made 3 of these. Part of the noise for my application is a small amount of back pressure and rattling from the passive vent itself, not the fan.
