Air Blowers--Which Angle?

An air blower comes in a variety of configurations--there are models that blow directly across the floor--the "zero degrees" model, versions that blow at an angle--"thirty degrees" models, and the "90 degrees" version that blow straight up at the ceiling. Each model has a different ideal use. The zero degree model is good for carpets, air circulation and other uses. The thirty degree version can be aimed at walls, aircraft, cars and other vehicles. The ninety degree version could be used to dry specific parts of aircraft, wet ceiling surfaces or racks that have been recently pressure washed. Many of these models are "fixed" at their aim, so choose carefully based on the use you intend to get out of the air blower.
