1.The TRP-250 Air-Cooled Roots Vacuum Pump delivers oil-free, low-noise, and energy-efficient performance for industrial vacuum systems. This guide covers its technical parameters, operation mechanism, benefits (compact design, fast startup, special gas handling), and FAQs to help you choose the best vacuum solution.

2. Working Principle

How the TRP-250 Roots Pump Works

• Dual Rotor Design: Two figure-8-shaped rotors rotate in opposite directions, creating a vacuum by trapping and expelling gas.

• Zero Contact Operation: Rotors maintain a precise gap, eliminating friction and oil contamination.

• Bypass Valve Protection: Automatically opens at high pressure differences (≥8000 Pa) to prevent overload.

• Requires a Backing Pump: Must be paired with a rotary vane or liquid ring pump for optimal performance.
