Air System Maintenance - Guide 5 - 2

Preventive maintenance is the solution to keeping your compressed air system in top condition. While the life cycle of any industrial air compressor typically exceeds ten years, proper maintenance is crucial to maintain performance and efficiency. Compressors can be divided into seven sub-assemblies; Pump or Airend, Motor, Drive Train, Lubricants, Controllers, Coolers, and Filters. Because these sub-assemblies are expensive components, they need to be maintained on a regular basis. In addition, the benefits of using genuine filters and maintenance parts and replacing them when needed should...

Hot compressed air contains large amounts of water vapor. When traveling downstream, the water vapor condenses into liquid and causes corrosion in piping, components, air tools and production equipment. Compressed air dryers remove harmful moisture and are an indispensible part of any clean air treatment process. Refrigerated Dryers Refrigerated dryers are very reliable and the most commonly used dryer type. They remove water from compressed air by cooling it so that the water vapor condenses and is separated. A refrigerated dryer consists of heat exchangers, refrigeration compressor,...

Refrigerated Dryers Condenser Unit Clogged condensers account for most dryer problems. .. Periodically clean the fins with compressed air or a bristle brush to ensure enough refrigerant is transformed into a liquid state, for proper heat removal in the evaporator. Do not bend or damage the fins of the heat exchanger during cleaning. Separator/Drain The most critical area for dryer performance is proper drain function at the separator. Separated water needs to be discharged from the system frequently to avoid reentrance into the air system. .. Check separator and drain function regularly by...

Aftercoolers reduce the air temperature caused by the compression process close to ambient levels, where the air can be treated further. Aftercoolers are either air or water-cooled and eliminate up to 80% of all water vapor. Filters Filter technology has steadily advanced to provide reliable removal of solid particles, oil aerosols, water, and hydrocarbon vapors. It is possible to produce air thousands of times cleaner than the air we breathe. When selecting filters, ensure that the liquid loading (amount of water or oil) as well as the solid particle size does not exceed the filter rating....

Kaeser Air Compressor Guide 7 Air-cooled Aftercoolers .. Clean heat exchanger fins with compressed air or a bristle brush. Be careful not to damage or bend fins. Water-cooled Aftercoolers .. Check for proper water pressure and inlet/outlet temperatures. .. Check heat exchanger on water and air side for fouling. Mineral deposits on water side negatively influence heat transfer. Clean or flush with special cleaning solvent if necessary. Moisture Separator with Drain .. Check separator filter element for pressure drop. .. Check drain for proper function. Rebuild mechanism if necessary. .....
