About Box Fans
Box fans put a powerful extractor inside an insulated case, so they move a lot of air with far less noise than a bare inline fan. They suit larger tents and grow rooms, and spaces where noise matters, such as a house or garage.
We stock acoustic box fans from Tornado and Green Box with 10", 12" and 14" outlets, from 1500 to 7000m³/hr, plus the Gorilla 12" rotating box fan. Box fans go out on our bulky item delivery service, or collect free from our West Bromwich shop.
How to choose a box fan
As a rough guide, choose a fan that can change the air in your space at least once a minute, with some headroom for the carbon filter and ducting. Match the outlet to your ducting, and pair the fan with a carbon filter rated for at least the airflow you run.

Box fan FAQs
Why choose a box fan over an inline fan?
The insulated case keeps running noise down, which helps in grow rooms inside a house or garage.
Can I control the speed?
The Tornado Pro EC has manual settings and a boost mode, and variable control through a compatible EC controller. See our fan speed controllers and ask us which suits your setup.
MDF or foam?
The Green Box MDF fan is a thick, moisture resistant box built to last in humid rooms. The foam version is lighter, so it is easier to hang and move, and the foam will not warp in high humidity.
