Overheating of bearings 1. 2. 3. 4. Insufficient lubrication. Bad lubrication system. Crankshaft bearings to tight. Belts too tight 1. 2. 3. 4. Add lubrication oil. Examine the system. Readjust load on bearings. Adjust belt tension Flywheel rotation slows down 1. 2. 3. Heavy lubrication oil. Drop in voltage.
CT SERIES CAP 410 RECOMMENDED STATEMENT ON DRYERS AND FILTERS Liquid water occurs naturally in air-lines as a result of compression. Moisture vapor in ambient air is concentrated when pressurized and condenses when cooled in downstream air piping. Compressed air dryers reduce water vapor concentration and prevent liquid water formation in compressed air lines. Dryers are necessary companion to air filters, aftercoolers, and automatic tank drains for improving the productivity of compressed air systems.
