We sell only genuine Dayton brand blowers. You may find other brands that are a few dollars cheaper, but DONT WASTE YOUR MONEY They are typically louder, overheat quicker, and dont last nearly as long.Air exchange is necessary to help fight CO2 depletion and to cool your grow room down for best plant growth. Theres no more efficient way of exchanging air than with an exhaust blower. Our blowers operate at very high static pressures. This gives plenty of power to move air down a long tube or from room to room. All exhaust blowers come ready to mount in place, power cord installed. To determine the approximate size blower you need, divide the cubic footage of the grow room by 5. This gives the CFM Cubic Feet per Minute of air movement required. This formula assumes that the blower must be large enough to replace all the air in the room in 5 minutes. Its better to oversize the fan than getting a fan that is too weak to get the job done.
