CYCLONE Oscillating Clamp+Monkey FanA revolution among small clip on monkey fans on the market, as it's the first oscillating fan. This model, thanks to its rotating head system, allows for improved air circulation with an oscillating ventilation motion of almost 180. It's black, like the rest of the Cyclone family, but with red blades to differentiate it from the regular Cyclone clip on monkey fan. It's truly the ideal fan for grow tents.
