Mammoth Foam Box Fan 12" 4250m2

The Mammoth Foam Box Fan is a high-output ventilation unit built for serious grow room airflow management. Designed to move large volumes of air efficiently, it helps maintain stable temperatures, humidity levels, and fresh air exchange — all critical factors for consistent plant performance in UK indoor grows.

The fan sits inside a rigid foam-insulated enclosure that significantly reduces noise and vibration compared to traditional boxed fans. This makes it ideal for stealth-conscious setups or shared spaces where quieter operation is important. The foam housing is also moisture resistant, standing up well to the humid conditions common in active grow rooms.

A heavy-duty motor is engineered for continuous running, delivering steady airflow without performance drop-off. The internal layout promotes smooth air movement, improving efficiency and helping your extraction or intake system work more effectively.

Lightweight yet robust, the Mammoth Foam Box Fan is easy to position within duct runs and integrates seamlessly into most ventilation setups — whether used for extraction, intake, or air circulation.
