What type of oil is required for air compressors?

The correct choice is detergents-free oil, which is crucial for ensuring the optimal performance of air compressors. This type of oil is formulated to reduce the buildup of sludge and deposits that can occur in the compressor's moving parts. By preventing such deposits, it helps maintain efficient operation and prolongs the lifespan of the equipment. Detergent additives can lead to the formation of residues that may interfere with the functionality of air compressors, ultimately causing mechanical problems and decreasing efficiency.

In contrast, high viscosity oil, low sulfur oil, and low temperature oil may not cater specifically to the needs of air compressors. High viscosity oil can inhibit the compressor's performance by making it harder for the components to move freely. Low sulfur oil might be relevant to some applications focused on emissions but is not a standard requirement for air compressors. Low temperature oil is relevant for specific operating environments but doesn't address the primary lubrication and cleanliness concerns essential for compressor operation. Therefore, using detergent-free oil ensures that the compressor runs smoothly without the risk of harmful deposits, enhancing reliability and performance.
