Air Preparation (Compressed Air Dryers & Air Filters)
Mitigating and reducing the dew point of compressed air in industrial automation is done by installing refrigerated, membrane and desiccant air dryers. Water and condensate removal from industrial compressed air is done through using either a water or air-cooled aftercooler.
There are three essential processes prior to machine operation to better preserve the cycle life of expensive industrial equipment and ensure reliable machine operation.
- Water removal
- Moisture removal
- Filtration to removal particulates, oils and condensate
Moisture is the enemy of pneumatic systems, and SMC has a wide array of air dryers to keep moisture out of your systems. A wide range of sizes are available to meet flow ranges from 10~1000 liters per minute (ANR) and dew points from -15 to -60 degrees C.
SMC's upstream air preparation filters separate and remove mist and particles in compressed air that is difficult to remove with standard air filters. Depending on the unit, removal of contaminants down to 0.01 micron is possible. Large capacity filters and centrifugal water separators are also available.
SMC offers both air-cooled and water-cooled type aftercoolers. They are able to cool high temperature compressed air down to 40 °C or less while efficiently removing moisture from the system.
SMC's line auto drain valves reliably discharges even viscous drainage without requiring a human operator. There are several variants including air operated, motor operated, and heavy duty float style.
