The imported mainframes of dry, oil-free air compressors provide maximum durability, quality and purity in the air to be produced. The stainless-steel screw components of dry, oil-free air compressors utilize special coatings to protect them against high temperatures. Dry, oil-free air compressors utilize high-efficiency motors that are designed to operate in a highly distorted environment with a lot of airborne dust and high ambient temperatures. They also use piping that has been coated to resist corrosion, thus allowing them to have a long life span. The use of dedicated control systems and high-precision frequency converters enables accurate control, an exceedingly stable performance and an ease of use while meeting a wide range of requirements for industrial air supply.
