Evidence is that amongst the wide assortment of techniques available, the most common are compressed air arrangements. Although considered to be the fourth utility and ideal for many factory applications, compressed air is at its most ineffective and costly when used with open pipe or wind jet nozzles. In fact, the use of compressed air for these applications will not only cause severe fluctuations in a factory's main line supply for other vital operations, but more importantly waste enormous amounts of precious energy. Adding the problems of oil and condensate filtration, the increased maintenance of a continually running compressor will be substantial.
