Can RKW - bulletproof design with intergrated temperature control.

Can-Fan RKW plastic tube fan is a temperature controlled backward centrifugal extractor, using a resistant plastic housing. The fan is equipped with an integrated electronic control of the airflow, according to the temperature of the extract air. Once the temperature is set using the rotating switch, the sensor that is located inside the fan, will determine the motor to increase the speed if the extract air temperature is above the selected one with 1°C, and to decrease the speed if the temperature drops below the selected one with 1°C. Speed control is achieved by winding taps, therefor causing no noise.

The Swiss made motor inside the Can-Fan RKW has an integrated thermal switch that will turn the motor off, if the working temperature reaches a dangerous level.

For efficient performance with the best possible results, we strongly recommend the use of Can-Fan RKW together with Can Filters.

How to Use Can RKW Duct Fans

Can RKW Fans can be used to draw air out of your grow-space via a carbon filter or just ducting. The fan can be mounted in the required location using the bracket provided. Many users prefer to use bungees to hang the fan from, which usefully reduce noise and vibration. The fan should be mounted so that the required air-flow direction matches the arrow mark on the casing. On the output side of the fan, slide your ducting over the outlet sleeve and secure it in place with a Duct Clip (not included).

Repeat for the inlet side or a fast-clamp can be used to connect the fan directly on to a carbon filter. If a carbon filter is to be fitted it is important that the filter is rated at a similar air-flow as the fan. An electrical feed to the Can RKW Fan is required which can be directly from the mains or via a fan-speed controller. This should be performed by an electrically competent person. A downloadable wiring diagram can be found under the "Attachments" tab above this description. Be sure the diagram is followed closely.

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. For Can RKW Fans, follow the wiring diagram on the case moulding, do not match up the wire colours to the wires inside as they follow the European wiring code. 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 Can RKW Fan can achieve by about 25% just on it's 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.
