An apparatus for transporting and supporting fire fighting ventilation equipment is disclosed. A fan support frame supports one or more ventilation fans thereon. Extending in an upward direction from the fan support frame are a pair of arms whose length may be adjusted. Pivotally attached to each arm near its upward end is a rearwardly extending leg. The length of each of the rearwardly extending legs may be individually adjusted. An adjustable length bracket is provided for each leg and arm combination to hold the two components apart at the desired angular distance. An extendable leg is also provided at the front of the fan support frame. Wheels are provided on the fan support frame so that one or more ventilation fans may be transported by an individual and the fans may be aimed at any angle of inclination by extending the legs so that they contact the surface underlying the apparatus.
