Acoustic Box Fan Kits — Still the Top Choice for Many Large-Scale Growers Box fans have proved themselves over decades of use in the hydroponics industry, which is why they're still extremely popular, especially with growers operating at larger scales. That's because box fans are solid and dependable, and they get the job done. There are other, more efficient options out there that are more economical, but a lot of folks are still very attached to the classic box fan, and won't use anything else. What's in Our Box Fan Kit? We've teamed these Vortex MDF box fans up with the equipment needed to get the best out of them. You get the fan, a Mammoth carbon filter, a five-metre length of black combi ducting and some duct clips to connect everything up. Mammoth carbon filters are filled with high-grade RC 48 activated carbon — the best source of carbon on the planet. They will completely destroy smells, ensuring that extracted air is 100% odour-free. These filters are built with tough, refined aluminium casings, and they offer a nice balance between cost-effectiveness and quality. Expect to get around two years out of it before you need a replacement. The supplied combi ducting is much tougher than regular aluminium flexi ducting, which is more prone to tearing. Combi ducting is much more resistant to tears, which helps to maintain the efficiency of your extraction system.
