Delta Breez 1200 CFM 8.5 in. 3-Speed Blower Fan in Blue, 55 dBA, 8 Hour Timer, 8-Unit Daisy Chain

The Delta 1200 CFM Air Mover boasts a 55 dBA noise level at max speed and a mere 1.4 Amp usage. At the lowest, 800 CFM setting, the noise level is a quiet 45 dBA with only 0.5-Amp usage. This means that it's about 20% quieter than similar models on the market. The digital control panel with LED display makes it easy to control the unit as well as see how many hours it's been running. PRO TIP: Due to the low Amp draw, you can daisy chain up to 8 units together. With a lightweight 12.4 lbs. design, arc-shaped handle, and balanced center of gravity it is also easy to carry. Each unit comes with a 10 ft. power cord so you can position the unit exactly where you need it.
