People behind Nash
Nash specializes in designing and manufacturing high-performance vacuum systems, integrating Roots blowers and liquid ring pumps for optimized efficiency and reliability. Our hybrid vacuum systems leverage the benefits of both technologies to deliver superior performance in demanding industrial applications.

Enhanced Performance with Hybrid Systems

Engineered multi-stage vacuum systems combine a Roots blower (vacuum booster) with a liquid ring pump as the primary vacuum source. The Roots blower is installed upstream of the liquid ring pump, enabling:

  • Higher pumping speeds and deeper vacuum levels than a standalone pump
  • Stable operation across fluctuating process conditions
  • Efficient handling of wet, dirty, or corrosive gases

Key Benefits of Nash Hybrid Vacuum Systems

  • High Performance: Faster evacuation times and deeper vacuum levels
  • Reliable & Robust: Designed for harsh operating conditions
  • Flexible & Customizable: Configurable based on process needs
  • Energy Efficient: Optimized power consumption for total system performance

How It Works

Roots blowers are positive displacement, two-lobe rotary blowers that operate without internal lubrication in the process chamber. Synchronized lobes transfer gas efficiently, minimizing condensation and material buildup. The liquid ring pump provides continuous, reliable operation and ensures safe handling of vapor-laden or aggressive gases.
