The MAN 20 Inch High Velocity Box Fan is a high velocity 20 inch box fan that moves 3,500 CFM from a 125W, 1500 RPM motor, with adjustable tilt and a tough polypropylene housing. For more models, see our Box Fans page.
Our Verdict
This fan moves far more air than a standard box fan while staying lighter than metal shop fans. The tilting head lets you aim the air, and the motor is made for all-summer running.
Higher speeds are loud and the motor uses more power than a basic box fan, so it suits large rooms, garages and gyms best.

Design
MAN has made fans in Mexico as a family-owned company since 1955. The housing and grille are high-impact polypropylene, tough but lighter than steel, on a stable base.
The head tilts up, down or straight ahead, and a carry handle makes it easy to move between a bedroom, garage, gym and office.
Controls
Three speeds take you from a gentle breeze to full power, and the listing notes that even low and medium move plenty of air.
There is no timer or remote. Many owners run it on low at night for steady white noise.
Placement Tips
Stand the fan where it can push air across the room toward where you sit or sleep, rather than into a wall or corner. Keep it on a flat, stable surface, and keep the cord out of walkways.
On cool evenings, a box fan facing into the room from an open window pulls in fresh air, and a second fan facing out of a window on the other side of the house pushes warm air out to create a cross breeze.
Running Costs and Care
Box fans use far less power than an air conditioner, so running one all night costs very little. Pairing it with your AC lets you raise the thermostat a little and stay comfortable.
Unplug the fan and wipe dust from the grilles and blades every few weeks during heavy use, since dust cuts airflow and adds noise. Store it clean and dry over winter, ideally in its box or a bag.
How It Compares
Against the KEN BROWN 20 Inch High Velocity Box Fan, the MAN lists less airflow but is lighter, with a polypropylene housing.
Against a standard fan like the Hurricane Classic Box Fan, the MAN lists more airflow and adds tilt, but is bigger and louder.
