$ 54.99 $ 83.99
SKU: YES1588

This 4" Inline Fan is able to move air through carbon filters, long stretches of ducting or grow light reflectors. With a tape flange, it is rather convenient for you to place the ducting on the blower and tape it in place. Exchange stale air with fresh air to keep temperature or humidity under control and cool your reflector with this top-quality blower!

**Tips: High-speed fan must have high Airflow Rate(CFM) and more than 2,000 RPM. Only high cfm is not a real good high-speed fan! Don't buy those high-speed fans just show the cfm parameter, but can't show the RPM and other professional parameters!

Tips: Effective treatment requires the exchange of air in your growing area in a period of several minutes. You can count the total cubic feet with multiplying length by width by height of your growing area. Then divide by the CFM(cubic feet per minute) of the fan, you will get the time that the fan exchange the air for your grow area. For example, if the size of your grow tent is 9' length x 9' width x 9' height, it contains a total of 729 cubic feet. With our 176CFM fan, you would treat your growing area within 5 minutes! Powerful and high-efficient for your grow room or grow tent!
