Rotron CP and EN regenerative blowers (photo) are engineered to provide safety and efficiency in hazardous and corrosive environments. Constructed from aluminum, these blowers are naturally spark- and corrosion-resistant, distinguishing them from other blowers that are typically made of steel or other materials that are vulnerable to corrosion and sparking. This advantage is further enhanced by the inclusion of stainless-steel nuts, bolts and hardware, standard across all Rotron regenerative blowers for chemical processing applications. In contrast, many comparable blowers opt for low-cost zinc-plated fasteners that are more susceptible to corrosion. The proprietary Chem Tough process used to fabricate Rotron regenerative blowers transforms the aluminum into an oxide ceramic with selected fluorocarbons, providing high levels of chemical resistance, hardness and permanent lubricity. Additionally, Rotron regenerative blowers feature full C-face motors designed to protect motor windings and bearings from corrosive gases and the airstream. — Bison, an Ametek business, Kent, Ohio
