How Tornado Acoustic Box Fans Work

Tornado Acoustic Duct Fans are used to move air to-and-from your grow area, removing excess heat and moisture, while replacing CO2 as it becomes depleted. Duct fans also tend to be used in conjunction with carbon filters to remove unwanted smells. Air is drawn through layers of charcoal and cleaned to remove odours before it reaches its exit point, keeping the area odour free. Duct fans are such an important part of any successful grow that it is worth investing in quality equipment to achieve the best possible results. Tornado fans are efficient and reliable, making use of a prestige Torin Sifan motor, which is designed and manufactured in Swindon. They move a LOT of air, and, as acoustic fans should be, they're extremely quiet. As an added extra, they also look the business!

Using Tornado Acoustic Box Fans

The Tornado Acoustic Box Fan should be mounted at the top of your grow room, in order to remove hot air as it travels upwards. You should ideally use either acoustic ducting or Phonic Trap. These forms of ducting are lined with insulation that will reduce the levels of noise generated by air as it moves over ridges and bends, creating friction

Ducting should be attached to the vents on the Tornado fan with duct clips (supplied separately) to ensure that the join is secure. If ducting comes loose and the extraction system is compromised, unwanted smells may escape, and heat and humidity levels may rise. For the same reason, it's advisable to connect the inlet vent of the fan to the carbon filter using a fast clamp (also available separately).

We recommend using these duct fans in conjunction with coil-type fan speed controllers rather than purely digital versions which can generate acoustic resonance, leading to humming and buzzing noises. SMSCom Hybrid controllers provide the quietness of coil-type controllers with intelligent room control, and are available separately.

Do not under any circumstances put your fingers into the spinning blades of a fan, especially an in-line type. Even a small fan has enough power to cause severe injury and loss of fingers. Just don't do it, no matter how tempted you are. Keep ducting runs as short as possible as every metre of ducting reduces the flow-rate that the fan can achieve. The more ducting attached, the lower the air-flow. Bear in mind that a carbon filter will reduce the air-flow that your fan can achieve by about 25% just on its own. When turning a corner with ducting try to create a swept bend rather than a sharp knee as this will reduce air-flow by the least amount and also help to keep wind-noise down. To further keep wind-noise down to a minimum, stretch flexi-ducting out as much as possible or use acoustic ducting.
