Model 5685 is designed to control static charge in mini-environments, laminar flow hoods and workstations. The Model 5685 features a unique aerodynamic design that ionizes a local area without disrupting laminar flow. Ideal in 12-24 inch distance applications with laminar air flow, the Model 5685 utilizes steady-state DC ion emission and Simco-Ion's IsoStat® Technology. IsoStat technology guarantees intrinsically balanced ionization. No complicated feedback circuits are required to maintain balance and adjustment is never needed. The Model 5685 is available in four different lengths and installation is fast, using easy-mount clips. Plug and play, the ionizer provides balanced ionization upon power up. Available with ultra-clean single crystal silicon emitter points, the Model 5685 meets ISO 14644-1 Class 3 standards (Fed. Std. 209e) Class 1 equivalent.
