The long-life CFE ion emitter used is made from a high-tech, space-age material (fine graphite filaments) that is virtually maintenance-free. The CFE emitter has a projected lifespan of five years or more and requires no trimming to maintain the crtically-sharp emiiter points (like SSE ion emitters do), since the diameter of the fibers is almost microscopically small (only 0.8 microns).

For use with Comtech Research models IG-133A, IG-133DG, and IG-133DGB.
