PCT No. PCT/AU94/00283 Sec. 371 Date Feb. 21, 1996 Sec. 102(e) Date Feb. 21, 1996 PCT Filed May 26, 1994 PCT Pub. No. WO94/27706 PCT Pub. Date Dec. 8, 1994An air drying and purification system for compressed air is disclosed. The system is adapted particularly for use with dental compressors. The system comprises: (a) a centrifugal separator chamber for at least partially drying and purifying cooled compressed air from a compressor by separating moisture and other contaminants from the compressed air, (b) a drying chamber containing a bed of absorbent material for absorbing moisture from the cooled, partially dried and purified compressed air, and (c) an assembly for periodically ventilating the separator and drying chambers. A particular feature of the system is that the compressed air that is vented periodically from the drying chamber is used to cool compressed air at elevated temperatures from the compressor.
