Ultra Quiet. Ultra Powerful.

Unlike most fans, which sound like a helicopter trying to claw its way through your ceiling, the Mammoth Foam Box Fan operates with the quiet serenity of a cat padding across carpet. The foam construction doesn’t just make the box ridiculously lightweight - it also smothers noise with the kind of efficiency that would make an assassin jealous. Inside each Mammoth Foam Box Fan is a thick layer of insulating, fire-resistant foam that traps sound and keeps your operation as discreet as a ninja at a library convention.

Premium Build Quality.

And the build quality? Absolutely top drawer. Mammoth haven’t just thrown together bits of plastic and prayers. No, the Mammoth Foam Box Fan is made from serious, moisture-resistant foam that shrugs off humidity and wetness like it’s in the SAS. Wooden box fans warp, rot, and eventually die with a squeal and a puff of damp sawdust. The Mammoth Foam Box Fan? It'll still be whirring away years after you’ve forgotten what a seedling even looks like.

Easy Plug & Play Set Up.

Each Mammoth Foam Box Fan comes pre-boxed, too — none of this faffing around with screwdrivers, missing parts, and regret. Straight out of the box, it’s ready to go, with a pre-wired power cable and anti-vibration mounts that keep everything nice and steady. If you don't fancy hanging it from the rafters, no problem. Mammoth thoughtfully provides a foam base plate so you can just plonk it down and get on with your life.

High Quality Motors. Bulletproof Reliablity

These things move immense quantities of air with the relentless drive of a Labrador at dinnertime. Sizes range from the compact but still wildly effective 10” 1500m³ model, all the way up to the 12” 4250m³ beast that could probably suck the air out of the moon if you pointed it the right way. Whether you’re running a modest home setup or you’re managing a grow operation the size of a small Amazonian village, there’s a Mammoth Foam Box Fan perfectly suited to your needs.

And because they’re powered by Mammoth’s trusted, high-quality motors, you get bulletproof reliability without needing to sell a kidney to afford it. Which is handy, because you’re going to need both kidneys if you want to keep up with how quickly your plants will start flourishing.

The Ultimate In Stealth Ventilation.

The Mammoth Foam Box Fan is everything a grower could want: quiet, powerful, lightweight, durable, and engineered with the sort of care and attention that you rarely see outside of fine watchmaking. Whether you’re new to the game or you’ve got a greenhouse that needs its own postcode, fitting a Mammoth Foam Box Fan is the single best upgrade you can make.

Your plants will love you. Your neighbours won’t know you exist. And you? You’ll wonder how you ever grew without one.
