Mammoth S-Max EC Extraction Kit - Complete Fan, Filter and Ducting Bundle
Best for: Growers who want a matched, ready-to-hang extraction setup - fan, carbon filter and ducting all sized to work together - without piecing it together component by component.
Our thoughts
Buying a fan and filter separately and hoping the airflow numbers line up is how a lot of new growers end up under-extracting. This kit sidesteps that by pairing an EC fan with a carbon filter that's actually rated for it. The EC motor is the standout bit here - quieter and considerably more efficient than a standard AC fan running the same airflow, and the built-in speed controller means you're not buying a separate dimmer.
The Mammoth S-Max EC Extraction Kit bundles a Mammoth S-Max EC-motor fan with a matched Mammoth carbon filter, five metres of ducting (your choice of white combi or acoustic aluminium), and duct clips to connect everything together. The S-Max fan uses EC (electronically commutated) motor technology rather than a standard AC motor, which lets it move a lot of air while using notably less energy - dropping fan speed by 10% cuts power draw by roughly the same amount, which isn't true of AC fans. It's housed in a lightweight aluminium casing lined with noise-dampening foam, bringing noise down to as low as 50dB, about the level of a quiet office.
Each kit size pairs the fan with a correctly-rated Mammoth carbon filter: the 6-inch kit uses a 150mm/645mm filter rated to 1000 m3/h, the 8-inch kit a 200mm/645mm filter rated to 1300 m3/h, and the 10-inch kit a 250mm/750mm filter rated to 1800 m3/h. Speed is controlled from 0-100% using the integrated controller on the back of the unit, no separate speed controller needed.
How it compares
EC-motor extraction kits like this sit above standard AC fan-and-filter combos on price, but the running-cost and noise advantages are real.
- Compared with a standard AC inline fan (like Mammoth's own TT range), the S-Max's EC motor uses less power for the same airflow and runs quieter at partial speed.
- Against other EC options such as Vortex Storm EC or RVK/Systemair EC fans, the S-Max is competitively priced when you factor in that the filter and ducting are already included and matched.
- Buying fan, filter and ducting as a kit works out cheaper than sourcing three separately-rated components, and removes the guesswork on sizing.
You're paying EC-fan money, but you're getting a fan, filter and ducting that are all correctly matched from the box - no separate shopping trip required.
Usage guidance
Installation is straightforward, but getting the airflow direction and ducting run right matters for both extraction and noise.
Connecting the kit
Use a short length of ducting and two of the supplied duct clips to join the fan's inlet end to the carbon filter. The third duct clip connects the main length of ducting to the fan's outlet, which should lead outside the grow space.
Hanging the system
Hang the fan and filter near the top of the grow area, since that's where the hottest, most humid air collects. The S-Max has built-in hanging hooks, so no extra hardware is needed for a standard tent setup.
Setting the speed
Plug the supplied speed controller into the back of the unit to adjust output from 0-100%. Run it at full speed during lights-on for maximum extraction, and dial it back at night when heat load drops, to save on noise and running cost.

Who this is for
- Growers setting up a new tent or room who want extraction sorted in one purchase
- Anyone upgrading from a noisy standard AC fan to something quieter for a bedroom or loft grow
- Growers who want lower running costs on a fan that's on for 12+ hours a day
- Those who'd rather not work out fan-to-filter airflow matching themselves
Best suited to growers who want a complete, correctly-sized extraction solution without sourcing components separately.
Our take
This is the extraction kit we point new growers towards when they ask "what fan and filter do I actually need." The EC motor's efficiency and quiet running make it worth the step up from AC, and having the filter pre-matched removes a common setup mistake.
Pick the size that matches your tent or room, choose acoustic ducting if noise is a concern, and you've got a proper extraction line sorted in one box. One we sell a lot of for new growers.
