Vortex Fan Kits - Exceptional Value for Money Vortex fans come with similar cases to RVK duct fans, but with much greater levels of performance, giving you everything you need to remove hot, moist, stale air in the most demanding indoor growing environments. The Vortex fan comes with a matched Mammoth carbon filter, black combi ducting and duct clips to connect everything up. Ideal for greenhouses, polytunnels, indoor gardens, and commercial growing operations. Please note: These kits are purchased to order so slightly extended lead times will apply Vortex Fans Vortex fans are similar in many ways to classic RVK fans. They have the same familiar shape, but come with lightweight aluminium casings that make them even tougher and more durable. Vortex fans really come into their own in terms of airflow, with specifications that blow their counterparts out of the water. For instance, the 4-inch RVK moves 184 cubic metres per hour, but the 4-inch Vortex moves an enormous 350 cubic metres of air per hour - that's nearly double the air movement! When you increase the airflow levels, you naturally increase the capacity for fans to generate extra noise. In this case there are, thankfully, no such issues. We've tested these fans out in the showroom and were very pleasantly surprised by the noise levels. Running the Mammoth TT fan helps control high temperatures by removing hot air from the growing area. At the same time, it removes excess moisture and draws fresh air in, maintaining a healthy CO2-rich environment for your plants. Mammoth Carbon Filters The Mammoth carbon filters included in these kits are specced to match the size and output rates of the TT fans. They provide effective odour control for indoor growing environments, ensuring fresh, clean air circulation at all times. Mammoth filters won't put too much of a drag factor on fans, allowing maximum airflow without compromising on air quality. They come with 50mm bed depths and utilise premium grade RC48 Australian carbon, which is regarded as the best source on the planet. Combi Ducting These kits come with white combi ducting, which is similar to traditional flexi ducting, but it's lined with plastic that makes it tougher and more resistant to tearing. Three duct clips are also included, which are used to connect up the system.
