Portable forced air heaters have a fan forcing air past an open flame, delivering heated air that contains exhaust fumes and odors. They are commonly used in open or well ventilated areas such as delivery bays, warehouses, outside workstations, etc. Forced air heaters offer an economical way to provide heat, providing there is not a need for people to be working in an enclosed heated area. Another type of direct fired equipment we carry are portable radiant heaters. Great for use outdoors, they are not affected by wind conditions and are virtually odor and smoke free while running.
