The SCS 980-T is an excellent tool for blowing particulate contamination off any surface. It releases a balanced stream of compressed, ionized air that neutralizes the static charge which can cause particulates to adhere to a surface. The discharge time from ±1000V to 100V is less than 1 second at 6 inches. This lightweight (12 ounces) ergonomic gun features a flexible air hose for ease of use. It also includes a disposable filter that collects particles from the air supply and can be easily replaced.
