Model 7612 – In-Stack IGS System
Model 7612 Systems allow placement of the IGS filter inside the stack or pipe, without risk of fouling the filter element, using a compact, self-contained filter/eductor assembly. In-stack systems are often chosen because of external space limitations, or because an external system would drop the gas temperature below its dew point, requiring the addition of heat tracing to prevent condensation. Standard filter element lengths range from 6" to 72", constructed of 316L stainless steel or Inconel® 600.
