Overview
Three fixed speeds drive the blades of this industrial floor fan, which can sit on the floor or on a table and tilt to aim the airflow. A powder coated metal body in black and yellow protects it, and a dual power supply accepts AC or DC.
The reason to consider it is the sheer airflow and the choice of mains or cordless operation, which suits a workshop or a site without reliable wiring. The limitation is the noise rating and the tool only label, because the battery and charger are not part of the listing.
Who it's for
Contractors, tradespeople and garage workers who already own compatible batteries and want a strong breeze across a work area. Light sleepers, or anyone expecting a battery and charger in the box, will find it loud and incomplete.
Pros and cons
- Very high airflow rating
- Works on AC or DC power
- Rugged powder coated metal
- Floor or table placement
- Loud at high speeds
- Battery not listed
- Heavy for a portable fan
- Warranty not listed
Performance notes
A large diameter high-velocity blade moves a dense column of air in a straight line, so it cools a person or dries a surface more than it circulates a whole room. The speed setting trades airflow for noise, and battery runtime depends on the pack used, which the listing does not provide.
