The standardized maintenance of air compressor equipment may be due to the odor emitted by the use of air compressors

1. The mineral oil used in the air compressor contains polar anti-wear additives, which are mainly phosphorus/sulfur/chlorine based. At high temperatures, the air contains a large amount of oxygen, and polar anti-wear additives oxidize to produce foul smelling gases. Polar anti-wear additives are generally not recommended for use at high temperatures, just like ordinary gear oil used on high-temperature chains, where the workshop is filled with foul smelling gases.

2. Substances brought in from the air, especially those containing phosphorus/sulfur/chlorine. Check if there are any chemical gases or dust containing chemicals around.

3. The rubber hose may be chloroprene rubber. The high-temperature lubricating oil dissolves it, and chlorine oxidizes at high temperature, producing a foul odor gas. The possible reason is the use of synthetic compressor oil with diesters. Diesters are prone to decomposition and are highly corrosive. Generally, rubber is prone to swelling (partial swelling), especially at high temperatures. Neoprene rubber is generally not recommended for use in high temperature and pressure environments.

4. The substitute oil is made green by adding heat-resistant pigments. Most pigments contain elements such as phosphorus, sulfur, and chlorine, and they contain oxygen and produce foul smelling gases at high temperatures. It’s best to test the oil, just like testing blood, to directly reflect the problem.
