Particulate contamination in the lube system can result in rapid damage to critical components. In order to protect the coal pulverizer lube system components, Pall recommends maintaining a fluid cleanliness level of ISO 16/13 or better. This can be accomplished through the use of Athalon AS grade (ß12 (c)≥ 1000) or finer filters.
