The reason why the air compressor emits foul smell during use

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

2. Substances brought into the air, especially those containing phosphorus/sulfur/chlorine. Check if there is any chemical gas or chemical dust around.

3. The rubber hose may be neoprene. The high-temperature lubricating oil dissolves it, and the chlorine is oxidized at high temperature, producing foul-smelling gas. The possible reason is that the synthetic compressor oil of diester is used. Diesters are easy to decompose, and at the same time, they are relatively corrosive. Generally, rubber is easy to swell (partially swell), especially at high temperatures. Neoprene is generally not recommended for use in high temperature and pressure environments.

4. In order to make the alternative oil green, pigments that are not resistant to high temperature are added. Most of the pigments contain elements such as phosphorus/sulfur/chlorine, and the pigments have oxygen and high temperature to produce malodorous gases. It is best to test the oil, just like the blood test, which directly reflects the problem.
