TRR Two-Stage Roots Blower – High Pressure Roots Blower with Maximum Efficiency

The TRR Series Two-Stage Roots Blower is a high-performance industrial blower system designed specifically for applications requiring higher pressure differentials that cannot be achieved by single-stage blowers. This series includes both two-stage series-connected Roots blowers and two-stage series-connected wet Roots vacuum pumps, offering a wide range of flow capacities and pressures to suit demanding industrial processes.

Why Choose a Two-Stage Roots Blower?

For Roots blowers and vacuum pumps, the pressure ratio in a single stage is generally limited to 2.2 due to concerns about efficiency and temperature rise. When a higher pressure ratio is needed, the TRR series offers the perfect solution. By connecting two blowers (or vacuum pumps) in series, the system can safely and efficiently deliver higher pressure outputs while maintaining reliable performance. To ensure stable operation, a mid-stage intercooler is integrated between the two stages, effectively reducing temperature rise and protecting internal components.
