Using Gekko Acoustic Box Fans:
The Gekko Acoustic Box Fan should be mounted in a suitable place using the four eye screw fixings supplied with the unit which are fitted into each corner of the top surface. Rope Ratchets are a great way to hang the Gekko fan so that its height can be adjusted if needs be. Alternatively, the fan can be mounted on a flat surface. Ideally, acoustic ducting should be used with this product to maintain sound at minimum levels. Acoustic fans can only do so much to reduce sound. As air travels through ducting, added noise is generated as it moves over ridges and bends, creating friction.
Ducting should be attached to the vents on the Gekko 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).
The Gekko Acoustic Box Fan is supplied with an IEC Connector, so that it can easily be connected to a power supply with a standard kettle lead. The Gekko Acoustic Box Fan has a clamp which closes over the IEC connection, ensuring that the cable cannot be accidentally pulled out. The supplied IEC cable is around 165cm long; locating the Gekko fan further away than this from a power supply will require the purchasing of a separate cable.
We recommend the 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 the intelligent room control of digital units, 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.
