PD+ 3200 Series Heavy Duty Booster

High pressure rotary lobe booster for air and process gas

A sustainable high performance solution for your high-stress overpressure applications.‍

‍

The PD+ 3200 is an industrial booster with rotating lobes designed for demanding air and process gas applications. From the Range PD Plus, it delivers high performance up to 1000 mbar of pressure, with reliable and robust continuous operation.

‍

Its design integrates ductile iron components, helical gears, and sparging lubrication to ensure Durability, Mechanical Stability and Longevity. Optimized sealing systems ensure contamination-free operation (oil-free air) and excellent control of leaks in sensitive environments.

‍

Available in several configurations (air, gas, single or double jacket, horizontal or vertical flow), the 3200 model adapts to a wide range of industrial applications, from pneumatic transport to pressurized processes, with options such as oil cooling for the most severe conditions.
