Roots Systems - Model Duragas Series -Rotary-Lobe Compressors
Roots Systems manufactures its own compressors – the Duragas series – for handling process gases. The Duragas series is designed and built for process applications in a wide variety of sizes, materials and sealing arrangements suitable for a wide range of gases, including corrosive, flammable, radioactive and toxic.
Our Duragas machines are splash lubricated as standard but include a wide ‘interspace’ between the inner gas seals and the bearing and lube oil seals. This acts as a catch pot, preventing lube oil from migrating into the process gas stream.
Roots Systems is one of the few manufacturers of rotary-lobe blowers in the world that comply with API Standard 619, making our Duragas series the first choice for the petrochemical, oil and gas industries, both onshore and offshore.
The Duragas series covers a range of flows from 5 to 50,000 m3/h (3 to 30,000 cfm).
Duragas machines can operate at inlet pressures down to 1 mbar (0.75 Torr) absolute.
Duragas machines can operate at inlet pressures over 150 bar (2175 psi).
Duragas machines can generate differential pressures up to 4.5 bar (65 psi) in a single stage.
