MTRH‑Series High‑Pressure Heavy‑Duty Roots Blower | MingTian ShanGu Brand

MingTian ShanGu MTRH series high‑pressure heavy‑duty roots blower adopts advanced two‑lobe involute impeller, specially developed for high differential pressure working conditions. Standard housing material is QT450 ductile iron; 2205 duplex stainless‑steel housing optional for corrosive gas medium. Produced by MingTian Group under ShanGu brand. Equipped with double‑oil‑tank reinforced lubrication and cooling, imported bearings, imported gears and imported screw noise shielding structure. MTRH delivers higher efficiency and excellent temperature‑rise control under high‑pressure heavy‑load, supports long‑term continuous heavy‑duty operation. It can work as positive pressure blower, and can be customized into V‑suffix roots vacuum pump for negative‑pressure process.

Key Technical Differences for Overseas Model Selection

• Impeller Profile Difference
  • MTRF / MTRG: two‑lobe cycloidal impeller, optimized for large‑flow performance under normal pressure.
  • MTRH: two‑lobe involute impeller, better efficiency and lower temperature‑rise under high differential pressure, purpose‑built for high‑pressure heavy‑duty applications.
• Maximum Pressure Capacity
  • MTRF, MTRG: typical max differential pressure up to 78.4 kPa.
  • MTRH: achieve up to 98 kPa high differential pressure, double‑oil‑tank enhanced lubrication‑cooling design for long‑term continuous high‑pressure operation.
• Flow‑Pressure Characteristic
  • MTRG: designed for ultra‑large volume flow output.
  • MTRH: not blindly pursuing maximum flow, but withstand higher pressure under same nozzle dimension.

Quick selection guide:
✅ Large‑flow with normal pressure → Choose MTRF / MTRG
✅ High differential pressure working condition → Prioritize MTRH

Typical Application Working Conditions

• High‑pressure pneumatic conveying system
• Sealed process gas pressurization
• Coal gas / biogas pressurization
• Chemical industry process air supply
• High‑pressure EPC turn‑key industrial projects
• Customizable V‑suffix roots vacuum pump for negative‑pressure process
