The basic principle of a dry oil-free air compressor is to gradually compress the air through the movement of screws or slides, thereby increasing its pressure. But unlike traditional air compressors, it adopts a unique design that does not require lubricating oil. During the compression process, no lubricating oil or lubricant is used, but lubrication between the screw or slide is achieved through special materials and coatings. This oil-free design ensures the purity of compressed air and avoids the pollution problems that traditional lubricants may introduce.

How does a dry oil-free air compressor achieve lubrication and compressed air? The key lies in the special lubricating materials and coatings. These materials form a thin but uniform lubricating film on the surface of the screw or slide, acting as a lubricant. This film not only reduces friction and wear between surfaces, but also effectively seals the air and prevents leakage. This design enables the dry oil-free air compressor to maintain good lubrication performance while maintaining high efficiency, ensuring reliable gas compression.

The TF series is a two-stage oil-free screw compressor with an integral box structure that integrates gas, oil, drive, cooling, and instrumentation. No specialized foundation is required for installation, just a flat concrete surface that can withstand a load of 1000kg/m2 is sufficient. Once the compressor arrives at the site, it can be put into operation by connecting the electricity, water, and gas pipelines.

Excellent system design

Integrated module structure design: The air-cooled and water-cooled units adopt the same standard size soundproof cover, which fully integrates the air end, cooler, motor and other components. According to the unit structure, it is divided into five functional areas: intake unit, compression unit, cooling unit (air-cooled, water-cooled), drive unit, and electronic control unit (frequency conversion). Each functional area can easily achieve function switching, product upgrading and non-standard customization. Minimize the footprint while ensuring internal maintenance space.

Cold and hot partition design, utilizing reasonable ventilation channels to quickly dissipate unit heat.

The soundproof cover undergoes multiple noise reduction treatments to filter out high-frequency noise.

The main motor of the compressor drives the air end through gears, achieving two-stage compression. It mainly includes the following parts: pneumatic system, air end, main motor drive system, cooling system, lubrication system, and HMI integrated control system.
