The Desco 50602 Chargebuster Overhead Ionizer with Lights, 2 Fans, 220VAC is a steady-state DC ionizer designed for use in ESD protected areas. This model has a 2' x 4' coverage area, and offers a discharge time (< 3 seconds at 18") and low offset voltage (±10 volts) to meet the required limits of ANSI/ESD S20.20 < ±35 volts tested per ANSI/ESD STM3.1 and ESD TR53. Its emitters are made of pure tungsten and spaced further apart to minimize ion recombination, increase discharge efficiency and provide a broader coverage area. The fans have 3 speeds (high, medium, low) which produce consistent performance at all 3 settings. The 50602 utilizes an auto-feedback system that continuously optimizes its performance and automatically alarms and shuts down should its supply voltage drop. This model includes a 700 lumen light panel (cool white) that provide additional illumination to the work area and improve visibility and productivity.
