Which size kit do I need for my Grow Tent?
There exists a (relatively) easy formula to work out which size extraction you need for your space, find out the volume in m3 (meters cubed) of your grow space with Width x Length x Height = Volume. then, Volume x 60 = Air Movement Per Hour (this will refresh the air in your grow room every minute).
If you are using a filter (which you are), Air Movement Per Hour x 1.2 = the amount of air your fan will need to move - use the figures below to match up your space to an RVK kit!
Bear in mind it's always better to over spec your fan and reduce its output with a controller, this gives you the flexibility to increase it's output to maintain optimum conditions for your plants, for example in the middle of summer.

How does the RVK Sileo Fan & Rhino Hobby Filter Extraction Kit work:
Our RVK & Rhino Hobby Extraction Kit contains everything you need to remove stale air and odours from a grow-space. All the parts are top quality and matched to work together perfectly. Systemair RVK fans are notoriously well-made and reliable and Rhino Hobby Filters are easily the best budget carbon filters that money can buy, though it must be noted that they will remain effective for roughly half the time of the Rhino Pro, at around 9 – 12 months. A fast clamp makes easy work of joining the fan and filter together while 5 metres of ducting and a duct clip allow you to vent to a convenient outlet. A power cable with a moulded mains plug for the extraction fan completes the set-up.
How to use the RVK Sileo Fan & Rhino Hobby Filter Extraction Kit
The mains cable should be wired into the fan by an electrically competent person. 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.
The Rhino Hobby carbon filters are shipped with the duct coupler part-screwed on the wrong way around to reduce the size of the packaging. Using an appropriate sized screwdriver, take out the screws holding the duct-coupler in place. Turn the duct-coupler over and replace the screws so that the duct-coupler sits firmly against the seal. Do not over tighten.
The intake side of the fan and the filter are joined together using the fast clamp. They can then be hung inside your grow-tent or grow-room (fixings are not supplied but bungee cords are a great way to keep fan-noise as low as possible).
Because warm air rises it always is a good idea to try to mount the fan and filter as high as possible in the grow-space. The aluminum flexi-ducting can then be fitted to the outlet side of the duct-fan and secured in place using the duct clip. The ducting can then be run to your air outlet.
Every 8-12 weeks the duct-coupler at one end and the bottom at the other end need to be swapped over. This evens out the wear at each end of the filter. If the ends are not changed every 8-12 weeks then the Rhino Hobby carbon filter will not last the full 9-12 months expected lifespan.
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 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.
Moisture degrades the performance of carbon filters. High humidity makes them ineffective at eliminating smells and reduces the expected life-span by a significant amount. Try to keep humidity at a reasonable level (between 40% and 60%) and both your carbon filter and your plants will benefit.
