Review on Simple Deluxe 24 Inch Industrial Wall Mount Fan – High Velocity, 3 Speed Commercial Ventilation Metal Fan for Warehouse, Greenhouse, Workshop, Patio, Factory, and Basement – Black by Roberto Smith

We bought these to cool our patio because it has a low roof so we couldn't install a ceiling fan. They're also great for: Keeping flies away from our home. The fan right outside our door keeps them from flying in. Blow BBQ smoke out of the house. The weather blows smoke from the grill straight into the patio, but these fans won't let that happen. We can even have a small hole under the roof. They are also very quiet at low frequencies. Video fan on lowest level. A little louder in the high register, but the man blows!
