"Cyclones have been around for more than 100 years, with the first patent issued in 1886. "They have been used ever since to separate particles from an air, gas or liquid stream without the use of barrier filters across a wide range of industries," says Pedro Araujo, CEO and cofounder of Advanced Cyclone Systems S.A. The Portugal-based company is exclusively dedicated to the development and commercialization of high-efficiency cyclone systems worldwide. "Cyclones do not function differently depending on the applications," Araujo says. "The fundamental principles remain the same."
Andy Cowan, vice president of Rees-Memphis Inc., says while the technology is old, cyclones have been relied upon for a long time because they are good at what they do. "They're a separator to redirect and make air do what you want it to do," Cowan says. "Dust will drop out, and you have clean air coming out."
