Rotary vane compressors for biogas

Rotary vane compressors for biogas


Ro-Flo® sliding vane compressors are ideally suited to handle corrosive and/or dirty gases such landfill and digester gases.

Their outstanding reliability and durability is inherent to the design of this oil-flooded vane compressor. The Ro-Flo units will deliver years of continuous service with no loss of volume or pressure, even in the most severe applications.

Because the only wearing parts are bearings, blades and seals, maintenance costs are minimal. When routine maintenance is required, the simplicity of the design makes this process easy on-site, without removing the compressor from the system.

All components use heavy-duty construction to ensure strength, durability and lasting value.

More than 20 models are available in both low and high-pressure configurations for a wide range of applications and industries.


  • Rotor blades are constructed of durable laminated clothimpregnated with phenolic resin, and are heat-treated to minimizewear at elevated temperatures
  • Self-adjusting, radially sliding vanes maintain constant pressure and flow rate


  • Inlet volumes: up to 6,271 m³/h
  • Pressure: up to 130 psi
