Energy Saving Rotary Oil Free Compressor For Semiconductor Manufacturing

Energy Saving Rotary Oil Free Compressor For Semiconductor Manufacturing

Oil Free Compressor Type and application

Oil-free compressors are used in applications where entrained oil carry-over is not acceptable, such as medical research and semiconductor manufacturing. However, this does not preclude the need for filtration as hydrocarbons and other contaminants ingested from the ambient air must also be removed prior to the point-of-use. Subsequently, air treatment identical to that used for an oil-flooded screw compressor is frequently still required to ensure a given quality of compressed air.

In an oil-injected rotary screw compressor

oil is injected into the compression cavities to aid sealing and provide a cooling sink for the gas charge. The oil is separated from the discharge stream, then cooled, filtered and recycled. The oil captures non-polar particulates from the incoming air, effectively reducing the particle loading of compressed air particulate filtration. It is usual for some entrained compressor oil to carry over into the compressed gas stream downstream of the compressor. In many applications, this is rectified by coalescer/filter vessels. In other applications, this is rectified by the use of receiver tanks that reduce the local velocity of compressed air, allowing oil to condense and drop out of the air stream to be removed from the compressed air system via condensate management equipment.
Variable speed compressor

While an air compressor powered by a variable speed drive can offer the lowest operating energy cost without any appreciable reduction in service life over a properly maintained load/unload compressor, the variable frequency power inverter of a variable speed drive typically adds significant cost to the design of such a compressor, negating its economic benefits if there are limited variations in demand. However, a variable speed drive provides for a linear relationship between compressor power consumption and free air delivery. In harsh environments (hot, humid or dusty), variable speed drives may not be suitable due to the sensitivity of the equipment.
