Introducing the X-8 Industrial Confined Space Ventilator Fans! THE ONE and THE ONLY confined space fan that offers a complete control of both air velocity and air volume with a variable speed control switch. The X-8 can handle any narrow space with its 8 diameter flex hoses ducting air up to 125 ft. Just like all the XPOWER products, the X-8 is super 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. The X-8 can be used without hoses to create high volume air circulation in gyms, hallways and other large areas. With its ducting hose, the X-8 is the perfect fan to deliver a continuous flow of fresh air to subterranean manholes and sewers.Powerful and energy efficient 1/3 HP induction motorLow 2.1A draw with 1000 CFM maximum airflow capacityVariable speed control switch20 ft. power cord 2-in-1 function: high velocity blower & powerful exhaust fanSuper lightweight, compact and durable ABS plastic housing designDual thermal protection
