Even if you are working to a budget, there are always options available for you if you are looking to upgrade your hydroponic grow room. We have hand crafted the ideal carbon filter extraction kits for those of you on a strict budget, but still wanting to get the most bang for your buck. Systemair have possibly one of the longest standing reputations as a brand name amongst most hydroponic grow shops. Coupling their RVK Sileo fans with the powerhouse carbon filter brand that is Rhino is naturally a winning combination.

They may not be as quiet when running as an acoustic box fan, but size per size, you will typically see the Systemair RVK extraction fans performing much better when placed under pressure (from using with a carbon filter). Of course, if there is any issue with noise levels then using premium insulated ducting helps to keep them down to a minimum.

Your complete extraction system is possibly the most important aspect of your grow room to get right. If your hydroponic extract fan is not suitable, then you will struggle with adequately refreshing CO2 levels, or controlling high temperatures. If your carbon filter is not up to the job it could either impact your fans performance or even worse, not even adequately scrub the air as intended. We have removed the possibility of error for you and hand selected the ideal combination of Systemair RVK fans and Rhino Carbon Filter, simply select the appropriate size kit for your hydroponic grow room.


Our Rhino Hobby fan kits contain:

  • High quality, Systemair RVK Sileo extraction fan
  • Hobby quality Rhino filter to remove any unwanted odours
  • Your choice of acoustically insulated ducting, or regular aluminium ducting
  • Highly durable ducting clips to ensure an air tight seal.
  • Everything you need for the ultimate carbon filter extraction kit!


Systemair have a long-standing reputation in the hydroponic industry. Many other competitors have come and gone all trying to steal Systemair’s well-earned rank as the go-to extract fan for hydroponic growers. Systemair have been developing and researching almost everything you can think of when it comes to moving air, so you can be entirely confident that when you buy an RKV extract fan, it will get the job done!


A high-quality filter is the back bone of the extraction system and something that should never fail you! Rhino Carbon Filters are pretty much a household name when it comes to hydroponics air filtration systems for exactly that reason. Rhino Filters are a UK company using arguably the finest quality of carbon for air filtration on the face of the planet.

Australian sourced RC412 carbon is not only optimally activated to ensure huge amounts of volatile compounds are adsorbed, but this particulate size has also proven to be one of the most optimal grades available for proper air filtration. So even with a bed depth of just 30mm, the Rhino Hobby filter can cope with even the most unforgiving of smells.

Rhino filters are often the carbon filter of choice for most indoor growers, not just because of their long-standing presence in the market, but also from the overall reliability and peace of mind that comes with using this calibre of carbon filter.


We have selected put together the right combination of fan and carbon filter for you, now all there is left to do is decide whether you want regular aluminium ducting or if you want to choose the acoustically insulated version. Of course, we would always recommend the acoustically insulated version to reduce any noise issues, but for those on a budget the aluminium ducting may be the way to go.

Just remember to bear in mind that it is often the physical movement of the air itself that creates the noise you hear, so insulated ducting ensures this excess noise does not become an irritation for you or, most importantly, any of your neighbours. This is of course particularly important for indoor garden in built-up urban environments.


Choosing the right equipment to work together in this scenario can be a bit of a mine-field. With the huge amount of different size options available, it can sometimes be a bit baffling to get the right size carbon filter, for the right size fan.

All hydroponic extraction fans have different motors inside of them. Just like any other motor, the more resistance you put on it, the more its performance reduces. Attaching a carbon filter creates exactly this sort of ‘resistance’ to an extraction fan. It creates a pressure on the fan, that in turn reduces the amount of air the fan can blow. All carbon filters are different sizes, so they all will exert a different amount of pressure and therefore cause different drops in air flow.

Most reputable manufacturers will provide the pressure drop curves for either their fans or their carbon filters, which you can use to figure out what affects you are going to see on the air flow, when you attach the two together. With these Rhino Hobby carbon filter extraction kits, we have taken that leg-work out of the equation, so all you need to do is plug it in and switch it on!


Always ensure the ducting is secured to the fan and filter with as great an air tight seal as possible. Without adequately connecting filter and fan to the duct-run, un-filtered air may by-pass your filter and find its way to the outside world.

Air leaks can be looked for by lighting a splint and running it along your extract line. If there are any gaps then you will see the smoke get sucked into the duct run, indicating you need to give more attention in this area to achieving a correctly air tight seal.

Try to avoid any bends, kinks or slackness in the duct run. These will all lower the amount of air being extracted through the system. Ideally have it as straight and as tight as possible to ensure as little back-pressure on the fan as possible, giving you the highest air movement possible.

Consider choosing a slightly larger fan and filter, then using alongside a fan speed controller. That way your fan won’t run on full power as often and generally operate at a quieter volume. It also gives you the failsafe of having the option to move more air come the hotter months.
