為了生產ISO 8573等級1品質的壓縮空氣，大多數操作人員使用活性炭吸附器，透過吸附的方式從壓縮空氣中去除油分子。由於活性炭也會吸收水蒸氣，在空氣中含有大量水蒸氣的情況下耗損尤其快速。在這個狀況下，活性炭吸附劑無法吸收油分子，因此下游壓縮空氣中的濃度會超過等級1品質的限值（> 0.01mg/m3）。為了長期以可靠的方式處理，達成一致的低殘油含量，壓縮空氣必須在進入活性炭之前進行乾燥......
Even high-quality compressed air system components are exposed to some wear. Preventive maintenance aimed at reducing the risk of failure or malfunction includes the timely replacement of wear and maintenance parts. Depending on the actual operation and the prevalent operating conditions, such parts should be replaced at least every 12 months.
A measurement error is the difference between a measured value of quantity and its true value. Such errors tend to become more frequent the longer a device is in operation. At some time, the deviations might be so great that they are no longer within the specifications, which means that quality is no longer assured.
By calibrating the device, the measurement error can be determined and documented. If the measurements are outside the permissible range, the device needs to be adjusted. In this process, the measuring instrument is reconfigured so that measurement errors are minimised and deviations from the setpoint value are within the device specifications.
Compressed air filters improve the quality of the compressed air by removing contaminants. As these tend to deposit on the filter material, the pressure drop increases gradually over time. To ensure that there is sufficient pressure available at the consumers, the compressor must compensate this pressure drop, which results in higher energy costs.
