🌟 How Cool is this Fan? 🌟

"It’s so easy to set up and basically, you just plug it in, and viola. It also has a speed controller built-in so I don’t have to mess around and go buy an extra one because it is ALREADY THERE. I can turn it up and down as much as I like and it is super quiet either way." - G. Simon.

✅ Powerful: The fan has a speed of 2500 RPM for an airflow of 195 CFM. Moves air through your target location efficiently for optimal ventilation! Great for extra cooling or removing pollutants in a closed area!

✅ Low-Noise Level: Its low noise design reduces sound output to just 30 decibels.

✅ Efficient Design: It has a lightweight and compact design as the fan housing and blades are made of durable ABS plastic.

✅ Adjustable:  It has a speed controller for adjusting fan speed to the desired level; one control switch for 3 settings: high, medium, or low.

✅  Easy Set Up: It has removable duct ends with locking tabs for quick removal and easy maintenance, and a power cord length of 5.9 feet for hassle-free setup. Making it easy to install for industrial, household, and horticulture ventilation applications for air clean and temperature control.
