Hyper Fan Stealth & Rhino Pro Filter Extraction Kit - Combi Ducting
Free UK Mainland Delivery when you spend £50
Stealth Hyper Fans come with an extra layer of casing and dampening foam to keep sound levels to a minimum, making them ideal for anybody who's concerned about excess noise. V2 models move even more air than the originals, and they do so while using very little power, so they'll save you an absolute fortune on your energy bills. They come in compact, stylish, lightweight steel casings that make them a doddle to hang. V2 Hyper Fans can also be used with a larger selection of fan controllers than V1 models (see below for more info).
Please note: V2 Hyper Fans are not compatible with Multi Phase Hyper Fan Controllers.
This kit includes a V2 Hyper Fan Stealth which improves on the original Hyper Fan by delivering even greater levels of static pressure, increased airflow and a higher degree of controllability (from 0% to 100%). V2s are also compatible with a larger selection of controllers, which now includes the EC Fan Speed Controller, EC1 and EC5.
Rhino Filters utilise RC412 Australian virgin activated carbon, which is widely regarded as the best available. They're also designed with 51% open area meshing, which optimises air flow, putting less drag on your fan (not that it's too much of an issue for the V2 Hyper Fan!). You'll get two years out of a Rhino Pro before it needs replacing, unlike cheap and nasty knock-offs that start to degrade within weeks...
Combi ducting is provided as standard, which is more robust than regular aluminium ducting and also fully lightproof.

Find out the volume of your grow space in cubic metres: width x length x height = volume
For example: 1.2m x 1.2m x 2.0m = 2.88m3
You'll need to have the capacity to replace this volume of air once per minute. Multiply the volume figure by sixty to work out the airflow needed per hour.
2.88m3 x 60 = 172.80m3
Carbon filters add some extra load to your fan. To account for this, multiply the required airflow by 1.2, which will give you some spare capacity.
172.80m3 x 1.2 = 207.36m3
Note that it is always better to over-spec your fan and regulate it with a controller. This gives you the flexibility to increase output levels if temperatures rise.
