This industrial confined space fan offers a variable speed control in a small size for any narrow space. With the optional 8 in. diameter ducting hose (not included), it can transport ducted air up to 125 ft. Just like all the XPower products, this model is very lightweight and compact. Their low amp and powerful, sealed motors can efficiently deliver dry air to ventilate, create negative air pressure or simply to help complete any drying process for a wide variety of construction applications. It can be used without hoses to create high volume air circulation in gyms, hallways and other large areas.
