Below is a list of Air Heaters manufacturers from Columbia, Maryland.

Air heaters are electric heaters that use air circulation or a blower device to heat areas for domestic or for industrial purposes. Air heaters range in size and shape, although the most common air heaters are large, portable, and either rectangular-shaped or barrel-shaped. They are constructed by installing heating elements in a casing; the heating elements remain stationary while air ducts rotate alternately to expose sections of the heating plate elements to the circulating air.
