Designed for larger confined space environments that require faster purge times. Its tough, lightweight polyethylene housing offers durability while the metal safeguards and steel fan offer greater safety. Two 8 in ports offer positive ventilation or fume extraction, and the metal base with feet offers greater stability. The electric 3/4 hp motor offers a higher CFM output and is cage-enclosed for protection. It also includes an On/Off switch and built-in carry handle for increased portability.
