What is the difference between oil-free and oil-flooded rotary screw compressors?

Oil-free rotary screw compressors can be mechanically loaded with pressure differences up to 12 bar, and oil-flooded compressors up to 20 bar. Higher pressure differences are possible in special cases. Flow volumes up to 60,000 m3/hr (~35,000 acfm) have been accommodated in these compressors.

What is an oil flooded screw compressor?

Oil-flooded screw compressors are similar to oil-free screws except that they inject oil, or rather, flood the process chamber with oil, which mixes with the process gas during the compression cycle (Fig. 9.59 ). This has several purposes: Fig. 9.59. Internals of the oil-flooded screw compressor.

Are dry screw compressors better than oil flooded screws?

However, dry screw compressors are more suitable for dirty gas services, high water content, or has other properties that would contaminate the oil of a flooded screw. For oil-flooded screws, accurate gas composition is critical so the correct lubricant can be selected.

What is a typical oil injection rate?

As an example, a typical oil injection rate is 27 liters per minute (7 GPM) per 170 m3 /hr (100 acfm) flow rate for air compressors. Dry screw compressors require that sealing devices be installed at each end of each rotor.
