• The working chamber consists of two symmetrical lobes of figure eight cross sections. These lobes rotate in unison in opposite directions by means of accurately meshed gear wheels. 
• The medium to be conveyed flows into the compressor housing encasing the rotors. As the lobe rotates the gaseous medium is alternately delivered by upper and lower lobe from the suction to the delivery side.
• The air delivered is guaranteed to be oil free, statically and dynamically balanced rotors ensure vibration free running and longer bearing life, the versatility of installation is vertical or horizontal flow of air or gases, heavy duty hardened and accurate timing gears maintain lasting clearances between matching lobes.
• Suitable for handling town gas, nitrogen, hydrogen, carbon dioxide, inert gases, etc.
