Ultra Quiet & High Powered Ventilation.
Let’s face it, grow rooms have a tendency to sound like a squadron of leaf blowers having a tantrum inside a tin shed. Not anymore. Meet the Mammoth S-MAX Pro EC Fans - a range of ultra-quiet, high-powered ventilation beasts from the clever boffins at Mammoth here in the UK. If you’re serious about growing but don’t want your entire neighbourhood wondering if you’re hosting a wind tunnel experiment in your spare bedroom, these are your new best mates.
These aren’t your run-of-the-mill extractor fans. The Mammoth S-MAX Pro EC Fans are the stealth bombers of the horticultural ventilation world. They’re built to move vast amounts of air with such decorum, they make a library seem raucous. And thanks to their streamlined, silenced metal housings lined with noise-dampening foam, they do it all while humming along at noise levels as low as 50 decibels - which, in technical terms, is about as loud as a lazy Tuesday in an accountant’s office.
Maximum Power. Complete Control.
Mammoth S-MAX Pro EC Fans use EC (Electronically Commutated) motor technology, which means they’re smart. Not in a “read Shakespeare and cry” kind of way, but in an “I’ll save you a fortune on electricity” sort of way. Compared to traditional AC fans, these EC dynamos chew through just half the energy. That’s not marketing fluff. A 50% reduction in energy usage means lower running costs, more sustainable operation, and more money left in your pocket for seeds, soil, and snacks.
Want more control? Of course you do. Each Mammoth S-MAX Pro EC Fan includes a built-in controller, allowing precise speed adjustment straight out of the box - no need to spend extra on fancy plug-in gadgets. If you only need 60% of the fan’s grunt, you can dial it back, and guess what? You’ll only use about 60% of the power. It’s beautifully efficient, like a chef who only uses one pan and still makes a three-course meal.
Serious Air Movement for Seriously Happy Plants.
Don’t let the low energy draw fool you. The Mammoth S-MAX Pro EC Fans are not whispery weaklings. These things move serious air. The 12-inch model, the heavyweight of the bunch, can shift up to 2987 cubic metres per hour. That’s enough airflow to keep your grow room cooler than a polar bear’s sunhat while delivering fresh, CO₂-rich air for your plants to guzzle up during photosynthesis.
Whether you’re running a 6-inch duct or going all in with the 315mm monster, Mammoth has you covered. This is a range built to suit every grower, from the space-conscious stealth cultivator in a cupboard, to the full-blown, warehouse-wielding herbal enthusiast.
Fully Compatible. Fully Controllable.
Set-up is about as easy as falling off a log—though far more rewarding. Each unit includes its own power lead and hanging attachments, making installation a breeze. Simply hook it up, plug it in, and enjoy the soothing sound of nothing happening. That’s because these fans don’t make a song and dance about their job—they just get on with it. Silently.
In a world where noise and inefficiency reign supreme, the Mammoth S-MAX Pro EC Fans are a breath of fresh, precisely regulated, whisper-quiet air. Whether you’re a grow tent tinkerer or a commercial grow room maestro, these fans are the silent workhorses you didn’t know you needed.
Stealthy. Powerful. Economical. The Mammoth S-MAX Pro EC Fan doesn’t just blow air - it blows the competition away.
