During routine maintenance of air compressors on-site, one common issue we encounter is cooling system failure. This often occurs due to blockages in the cooling passages, which can be caused by accumulated dust, oil residues, or scale deposits. When these blockages restrict airflow or coolant flow, the compressor overheats, leading to reduced efficiency, increased wear, and potential damage to internal components.

Regular inspection and cleaning of the cooling fins, air filters, and coolant channels are essential to prevent blockages and ensure reliable compressor operation. In severe cases, professional on-site servicing may be required to flush the system, replace clogged components, or restore optimal coolant circulation.
