    The unstoppable rise of Isomax Acoustic Fans has been one of the major success stories of recent years in the UK indoor gardening market. With a reassuringly robust design and high quality components, each of the four units will comfortably help you overcome the challenges of extracting air from a modern grow room. Key features include the innovative baffle and acoustic lined chamber (much like a very large silencer) that successfully combine to minimise overall noise output whilst allowing for movement of gargantuan amounts of air. Both of the two smaller fans also provide convenient inbuilt fan speed controllers, offering even more value for money! Very highly recommended! Learn More

    Good air exchange is an important consideration in any grow room, since CO2 levels must constantly be replenished, temperatures skillfully managed, humidity levels harnessed and bugs blocked out. Made by Systemair of Germany, these RVK turbo fans are quiet running, powerful and ideal for connecting up to our superb selection of carbon filters and silencers.

    Normally you would use one fan as part of an extraction system to take away the stale air from inside your grow room and another as part of an intake system to bring in fresh air from outside of it. In some instances, such as smaller set-ups, it is possible to get by with a single extractor fan which is used with a carbon filter and ducting parts to remove stale air from the grow room whilst fresh air is sucked into the grow room via vents in doors, windows and walls. RVK Systemair Extractor Fans are suitable whatever method you choose to use and get a full recommendation from us!

    Choose the model that is right for you from the variety of different sizes on offer by referring to the table further down the page. Each RVK fan is supplied with a mounting bracket and replacements/spares of these components are available (call 0333 003 22 96 for further details). You will need a separate power cable to operate your fan - see the related items below to add this product to your basket.

    For the creation of an effective extraction system, in addition to the fan we also recommend getting a decent Carbon Filter, a suitable length of Ducting, a Fast Clamp, 2 x Quick Release Duct Clips and 2 x Rope Ratchets. If you want to put together an intake system, on top of the fan you will require a suitable length of Ducting and a Quick Release Duct Clip.
