Compatibility & Application Notes

  1. Only for DM45‑LP low‑pressure version. Cannot directly replace DM45‑HP high‑pressure air end (HP part number 2636017549). Rotor assembly, safety valve and piping are non‑interchangeable. Improper installation will cause severe air‑end damage.
  2. Controlled by rig EARS system for constant‑pressure variable‑air‑volume output.
  3. Part interchange: 57577033 (Epiroc) = 2657577033 (Ingersoll‑Rand OEM), fully interchangeable for original assembly.
