18″ HIGH VELOCITY METAL WALL FAN

Description

The 18-inch High Velocity Metal Wall Fan is a heavy-duty circulation fan built for large grow rooms and commercial growing environments where standard clip fans simply don’t deliver enough airflow. With a steel-bodied construction and a powerful motor, this wall-mounted fan moves a high volume of air across a wide area — helping to maintain even temperature, reduce humidity hot spots, and strengthen plant stems through consistent air movement. We recommend wall fans of this type for any grow space above 3 x 3 metres where a single oscillating floor fan would leave dead zones.

Why Air Circulation Matters in the Grow Room

Air circulation does far more than simply cool your plants. Consistent airflow across the canopy helps prevent the stagnant air pockets that allow botrytis and powdery mildew to take hold. It also strengthens stems by promoting a natural swaying motion — a process known as thigmomorphogenesis — which leads to thicker cell walls and more self-supporting plants. In a grow room where extraction systems change the air volume regularly, a wall fan ensures that fresh incoming air is mixed evenly rather than stratified in layers.

Wall Mounting for Permanent, Adjustable Airflow

Mounting this fan to the wall frees up floor and bench space compared to pedestal fans, and positions the airflow precisely where it is most effective — directed horizontally across the canopy rather than upward from below. The adjustable tilt head allows you to angle the airflow up into the light zone or down across the substrate surface depending on where temperature and humidity management is needed most.

The metal construction makes this fan a significantly more durable option than plastic-bodied alternatives. It handles the warm, humid environment of a grow room better over a long service life, and the blades are less prone to warping under sustained use.

Suitable for grow rooms, polytunnels, commercial greenhouses, and any large indoor growing environment where high-volume air circulation is needed. 18-inch steel blade. Wall-mounting bracket included.
