RVK 125 FAN
Systemair 5 Inch RVK 125E2-A1 Extractor Fan
The Systemair RVK 5-inch (125mm) In-line Duct fan is a high quality intake/outlet fan for extracting old, stale air from your grow-space or for supplying it with fresh air. The fans are housed in a lightweight yet robust fibreglass and plastic casing with external ports for easy connection to ducting, filters, airsocks or other 5-inch (125mm) diameter accessories. The fan can be powered directly from the mains or via a fan-speed controller (not included) to control the fan-speed and air-flow. Systemair RVK fans are very well-made and reasonably quiet during use. A bracket is included for ease of mounting.
Systemair RVK 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. 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. For RVK 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 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.
