Air Drying Application

Explore Graver Technologies' filters for compressed air dryers.

Clean, dry compressed air is crucial in various industries, often referred to as a "fourth utility." It is used for a wide range of applications, from powering pneumatic tools to operating critical instrumentation and packaging processes. The compressed air drying process involves several key components, such as compressors, aftercoolers, separators, prefilters, dryers, afterfilters, and receivers. The presence of water, oil, and solid contaminants in compressed air systems can lead to issues like rust, scaling, frozen lines, and process contamination. Different quality levels of compressed air exist based on applications, ranging from plant air to breathing air. The dryness level required and contaminant removal allowed by end-use applications significantly impact the quality level of compressed air. Key elements include the type of dryer affecting dryness level, the role of prefilters and after-filters in contaminant removal, and the use of coalescers to remove oil and water aerosols. An after-filter is crucial for removing desiccant dust and preventing potential contamination in downstream processes.
