The AD‑IS® module consolidates the air dryer, purge reservoir, governor, and four pressure protection valves into a single assembly, cutting leak points and simplifying scheduled maintenance compared to conventional charging system designs. The self‑contained purge reservoir regenerates the desiccant bed without drawing from the primary or secondary service tanks, so brake circuit pressure stays stable through every purge cycle. The spin‑on desiccant cartridge swaps out in under 10 minutes without removing the unit from the vehicle. K049199 is a direct service replacement for heavy‑duty air brake systems requiring a standard‑purge, 12‑volt, non‑PuraGuard AD‑IS® air dryer assembly.
