Rotary (screw) air compressor oil S4
Product Introduction
This product is made from high-quality synthetic hydrocarbon base oil, added with high-performance composite additives, and blended using advanced production processes. It is a high-quality lubricating oil for screw and blade air compressors, providing good protection for compressors. This product is classified into grades 32 and 46 based on its 40 ℃ kinematic viscosity.
Product advantages
Excellent antioxidant performance and thermal stability, preventing high-temperature oil deterioration, reducing the formation of sludge and sediment, and prolonging oil change cycles.
Good viscosity temperature performance and low-temperature fluidity ensure the normal operation of the equipment within a wide temperature range.
Good oil-water separation performance, allowing for rapid separation of water entering the oil.
Excellent anti-corrosion and rust prevention performance can ensure excellent rust prevention protection under harsh working conditions.

scope of application
Mainly recommended for rotary screw and blade air compressors.
Do not use for lubrication of compressed oxygen, ammonia, chlorine, and other acidic gas air compressors.
precautions
According to the regulations for equipment oil, select oil with appropriate quality and viscosity levels; Storage containers must be dedicated, and during storage and transportation, they must be waterproof, moisture-proof, and prevent mechanical impurities from entering; Prevent foreign object contamination; Prevent mixing with other oil products.
On site maintenance personnel need to regularly check the lubricating oil level: when the compressor is unloaded, the lubricating oil level is around 1/5 of the window; When the compressor is loaded, the lubricating oil level is between 1/2 and 3/4 of the sight window. Too little lubricating oil can cause high exhaust temperature of the compressor, but too much can increase the consumption of lubricating oil, not only wasting lubricating oil, but also affecting the stable operation of the unit.
When the air filter element, sealing gasket, oil filter, oil and gas separator and other accessories cannot meet the usage requirements, they should be replaced in a timely manner, and the use of low-quality three filters is strictly prohibited. Replace spare parts on time and do not reuse them.
According to the air humidity conditions, the equipment should be regularly drained. Water and oil will form an emulsion, which will greatly reduce the adhesion of lubricating oil and is not conducive to the lubrication of the equipment.
The oil change cycle of screw air compressor oil depends on the quality of the inhaled air, working cycle, working environment, and equipment maintenance. If the environment is very harsh (such as high dust and humidity), it is recommended to shorten the oil change cycle appropriately. For specific oil change cycles, please consult with Taihang sales representatives.
