Exair’s latest Long Super Ion Air Knives neutralize static electricity while blowing away dust and particulates from printed surfaces, paper, plastics, and three dimensional shapes up to 96” (2,438 mm) across. A wide laminar airstream full of static eliminating ions is effective at high speeds and provides reliable cleaning at distances up to 20 feet away. The air knife requires a minimal amount of compressed air at 5 PSIG to entrain high volumes of surrounding room air. An electrically powered static control bar fills the uniform sheet of air with a high concentration of positive and negative ions. The laminar airstream increases the surface exposure to the ions, making it effective for high speed processes and over long distances. Force is adjustable from a blast to a breeze. Long Super Ion Air Knives are available in 60" (1,524 mm), 72" (1,829 mm), 84" (2,134mm), and 96" (2438 mm) lengths. Prices start at $1,739. EXAIR CORP., Cincinnati, OH. (800) 903-9247.
